- NavigateTool (navigate_browser) - navigate to a URL
- NavigateBackTool (previous_page) - wait for an element to appear
- ClickTool (click_element) - click on an element (specified by
selector)
- ExtractTextTool (extract_text) - use beautiful soup to extract text
from the current web page
- ExtractHyperlinksTool (extract_hyperlinks) - use beautiful soup to
extract hyperlinks from the current web page
- GetElementsTool (get_elements) - select elements by CSS selector
- CurrentPageTool (current_page) - get the current page URL
This notebook showcases how to implement a multi-agent simulation where
a privileged agent decides who to speak.
This follows the polar opposite selection scheme as [multi-agent
decentralized speaker
selection](https://python.langchain.com/en/latest/use_cases/agent_simulations/multiagent_bidding.html).
We show an example of this approach in the context of a fictitious
simulation of a news network. This example will showcase how we can
implement agents that
- think before speaking
- terminate the conversation
Tradeoffs here:
- No lint-time checking for compatibility
- Differs from JS package
- The signature inference, etc. in the base tool isn't simple
- The `args_schema` is optional
Pros:
- Forwards compatibility retained
- Doesn't break backwards compatibility
- User doesn't have to think about which class to subclass (single base
tool or dynamic `Tool` interface regardless of input)
- No need to change the load_tools, etc. interfaces

This PR introduces a Blob data type and a Blob loader interface.
This is the first of a sequence of PRs that follows this proposal:
https://github.com/hwchase17/langchain/pull/2833
The primary goals of these abstraction are:
* Decouple content loading from content parsing code.
* Help duplicated content loading code from document loaders.
* Make lazy loading a default for langchain.
### Summary
Updates the `UnstructuredURLLoader` to include a "elements" mode that
retains additional metadata from `unstructured`. This makes
`UnstructuredURLLoader` consistent with other unstructured loaders,
which also support "elements" mode. Patched mode into the existing
`UnstructuredURLLoader` class instead of inheriting from
`UnstructuredBaseLoader` because it significantly simplified the
implementation.
### Testing
This should still work and show the url in the source for the metadata
```python
from langchain.document_loaders import UnstructuredURLLoader
urls = ["https://www.understandingwar.org/sites/default/files/Russian%20Offensive%20Campaign%20Assessment%2C%20April%2011%2C%202023.pdf"]
loader = UnstructuredURLLoader(urls=urls, headers={"Accept": "application/json"}, strategy="fast")
docs = loader.load()
print(docs[0].page_content[:1000])
docs[0].metadata
```
This should now work and show additional metadata from `unstructured`.

## Background
fixes#2695
## Changes
The `add_text` method uses the internal embedding function if one was
passes to the `Weaviate` constructor.
NOTE: the latest merge on the `Weaviate` class made the specification of
a `weaviate_api_key` mandatory which might not be desirable for all
users and connection methods (for example weaviate also support Embedded
Weaviate which I am happy to add support to here if people think it's
desirable). I wrapped the fetching of the api key into a try catch in
order to allow the `weaviate_api_key` to be unspecified. Do let me know
if this is unsatisfactory.
## Test Plan
added test for `add_texts` method.
This notebook showcases how to implement a multi-agent simulation
without a fixed schedule for who speaks when. Instead the agents decide
for themselves who speaks. We can implement this by having each agent
bid to speak. Whichever agent's bid is the highest gets to speak.
We will show how to do this in the example below that showcases a
fictitious presidential debate.
It makes sense to use `arxiv` as another source of the documents for
downloading.
- Added the `arxiv` document_loader, based on the
`utilities/arxiv.py:ArxivAPIWrapper`
- added tests
- added an example notebook
- sorted `__all__` in `__init__.py` (otherwise it is hard to find a
class in the very long list)
Tools for Bing, DDG and Google weren't consistent even though the
underlying implementations were.
All three services now have the same tools and implementations to easily
switch and experiment when building chains.
The following error gets returned when trying to launch
langchain-server:
ERROR: The Compose file
'/opt/homebrew/lib/python3.11/site-packages/langchain/docker-compose.yaml'

services.langchain-db.expose is invalid: should be of the format

Solution:
Change line 28 from - 5432:5432 to - 5432
One of our users noticed a bug when calling streaming models. This is
because those models return an iterator. So, I've updated the Replicate
`_call` code to join together the output. The other advantage of this
fix is that if you requested multiple outputs you would get them all –
previously I was just returning output[0].
I also adjusted the demo docs to use dolly, because we're featuring that
model right now and it's always hot, so people won't have to wait for
the model to boot up.
The error that this fixes:
```

- added a few missing annotation for complex local variables.
- auto formatted.
- I also went through all other files in agent directory. no seeing any
other missing piece. (there are several prompt strings not annotated,
but I think it’s trivial. Also adding annotation will make it harder to
read in terms of indents.) Anyway, I think this is the last PR in
agent/annotation.
The sentence transformers was a dup of the HF one.
This is a breaking change (model_name vs. model) for anyone using
`SentenceTransformerEmbeddings(model="some/nondefault/model")`, but
since it was landed only this week it seems better to do this now rather
than doing a wrapper.
This notebook shows how the DialogueAgent and DialogueSimulator class
make it easy to extend the [Two-Player Dungeons & Dragons
example](https://python.langchain.com/en/latest/use_cases/agent_simulations/two_player_dnd.html)
to multiple players.
The main difference between simulating two players and multiple players
is in revising the schedule for when each agent speaks
To this end, we augment DialogueSimulator to take in a custom function
that determines the schedule of which agent speaks. In the example
below, each character speaks in round-robin fashion, with the
storyteller interleaved between each player.
Often an LLM will output a requests tool input argument surrounded by
single quotes. This triggers an exception in the requests library. Here,
we add a simple clean url function that strips any leading and trailing
single and double quotes before passing the URL to the underlying
requests library.

2. SalesConversationChain - generate next message

Simplifies the [Two Agent
D&D](https://python.langchain.com/en/latest/use_cases/agent_simulations/two_player_dnd.html)
example with a cleaner, simpler interface that is extensible for
multiple agents.
`DialogueAgent`:
- `send()`: applies the chatmodel to the message history and returns the
message string
- `receive(name, message)`: adds the `message` spoken by `name` to
message history
The `DialogueSimulator` class takes a list of agents. At each step, it
performs the following:
1. Select the next speaker
2. Calls the next speaker to send a message
3. Broadcasts the message to all other agents
4. Update the step counter.
The selection of the next speaker can be implemented as any function,
but in this case we simply loop through the agents.

Test for #3434 @eavanvalkenburg
Initially, I was unaware and had submitted a pull request #3450 for the
same purpose, but I have now repurposed the one I used for that. And it
worked.

In this notebook, we show how we can use concepts from

agents.
Apart from being unnecessary, postgresql is run on its default port,
which means that the langchain-server will fail to start if there is
already a postgresql server running on the host. This is obviously less
than ideal.
(Yeah, I don't understand why "expose" is the syntax that does not
expose the ports to the host...)
Tested by running langchain-server and trying out debugging on a host
that already has postgresql bound to the port 5432.

So, this is basically fixing the same things as #1517 but for GCS.
### Problem
When loading GCS Objects with `/` in the object key (eg.
folder/some-document.txt) using `GCSFileLoader`, the objects are
downloaded into a temporary directory and saved as a file.
This errors out when the parent directory does not exist within the
temporary directory.
### What this pr does
Creates parent directories based on object key.

My attempt at improving the `Chain`'s `Getting Started` docs and

At present, the method of generating `point` in qdrant is to use random
`uuid`. The problem with this approach is that even documents with the
same content will be inserted repeatedly instead of updated. Using `md5`
as the `ID` of `point` to insert text can achieve true `update or
insert`.

Updated `Getting Started` page of `Prompt Templates` to showcase more
features provided by the class. Might need some proof reading because

hitch was that mmap needs to be disabled when loading LoRAs or else you

This PR adds support for providing a Weaviate API Key to the VectorStore
methods `from_documents` and `from_texts`. With this addition, users can
authenticate to Weaviate and make requests to private Weaviate servers
when using these methods.
## Motivation
Currently, LangChain's VectorStore methods do not provide a way to
authenticate to Weaviate. This limits the functionality of the library
and makes it more difficult for users to take advantage of Weaviate's
features.
This PR addresses this issue by adding support for providing a Weaviate
API Key as extra parameter used in the `from_texts` method.
## Contributing Guidelines
I have read the [contributing
guidelines](72b7d76d79/.github/CONTRIBUTING.md)
and the PR code passes the following tests:
- [x] make format
- [x] make lint
- [x] make coverage
- [x] make test
Now it is hard to search for the integration points between
data_loaders, retrievers, tools, etc.
I've placed links to all groups of providers and integrations on the
`ecosystem` page.
So, it is easy to navigate between all integrations from a single
location.
### Background
Continuing to implement all the interface methods defined by the
`VectorStore` class. This PR pertains to implementation of the
`max_marginal_relevance_search_by_vector` method.
### Changes
- a `max_marginal_relevance_search_by_vector` method implementation has
been added in `weaviate.py`
- tests have been added to the the new method
- vcr cassettes have been added for the weaviate tests
### Test Plan
Added tests for the `max_marginal_relevance_search_by_vector`
implementation
### Change Safety
- [x] I have added tests to cover my changes

This PR addresses several improvements:
- Previously it was not possible to load spaces of more than 100 pages.
The `limit` was being used both as an overall page limit *and* as a per
request pagination limit. This, in combination with the fact that
atlassian seem to use a server-side hard limit of 100 when page content
is expanded, meant it wasn't possible to download >100 pages. Now
`limit` is used *only* as a per-request pagination limit and `max_pages`
is introduced as the way to limit the total number of pages returned by
the paginator.
- Document metadata now includes `source` (the source url), making it
compatible with `RetrievalQAWithSourcesChain`.
- It is now possible to include inline and footer comments.
- It is now possible to pass `verify_ssl=False` and other parameters to
the confluence object for use cases that require it.
Small improvements for the YouTube loader:
a) use the YouTube API permission scope instead of Google Drive
b) bugfix: allow transcript loading for single videos
c) an additional parameter "continue_on_failure" for cases when videos

d) support automated translation for all languages, if available.

Currently `langchain.tools.sql_database.tool.QueryCheckerTool` has a
field `llm` with type `BaseLLM`. This breaks initialization for some
LLMs. For example, trying to use it with GPT4:
```python
from langchain.sql_database import SQLDatabase
from langchain.chat_models import ChatOpenAI
from langchain.tools.sql_database.tool import QueryCheckerTool
db = SQLDatabase.from_uri("some_db_uri")
llm = ChatOpenAI(model_name="gpt-4")
tool = QueryCheckerTool(db=db, llm=llm)
# pydantic.error_wrappers.ValidationError: 1 validation error for QueryCheckerTool
# llm
# Can't instantiate abstract class BaseLLM with abstract methods _agenerate, _generate, _llm_type (type=type_error)
```
Seems like much of the rest of the codebase has switched from `BaseLLM`
to `BaseLanguageModel`. This PR makes the change for QueryCheckerTool as
well

### Summary
Adds a loader for rich text files. Requires `unstructured>=0.5.12`.
### Testing
The following test uses the example RTF file from the [`unstructured`
repo](https://github.com/Unstructured-IO/unstructured/tree/main/example-docs).
```python
from langchain.document_loaders import UnstructuredRTFLoader
loader = UnstructuredRTFLoader("fake-doc.rtf", mode="elements")
docs = loader.load()
docs[0].page_content
```

Alternative to #3078 that updates the typing
I think the logic of
https://github.com/hwchase17/langchain/pull/3684#pullrequestreview-1405358565
is too confusing.
I prefer this alternative because:
- All `Tool()` implementations by default will be treated the same as
before. No breaking changes.
- Less reliance on pydantic magic
- The decorator (which only is typed as returning a callable) can infer
schema and generate a structured tool
- Either way, the recommended way to create a custom tool is through
inheriting from the base tool

a privileged agent decides who to speak.

Pros:
- Forwards compatibility retained

which also support "elements" mode. Patched mode into the existing
`UnstructuredURLLoader` class instead of inheriting from
`UnstructuredBaseLoader` because it significantly simplified the
implementation.
### Testing
This should still work and show the url in the source for the metadata
```python
from langchain.document_loaders import UnstructuredURLLoader
urls = ["https://www.understandingwar.org/sites/default/files/Russian%20Offensive%20Campaign%20Assessment%2C%20April%2011%2C%202023.pdf"]
loader = UnstructuredURLLoader(urls=urls, headers={"Accept": "application/json"}, strategy="fast")
docs = loader.load()
print(docs[0].page_content[:1000])
docs[0].metadata
```
This should now work and show additional metadata from `unstructured`.

## Background
fixes#2695
## Changes
The `add_text` method uses the internal embedding function if one was
passes to the `Weaviate` constructor.
NOTE: the latest merge on the `Weaviate` class made the specification of
a `weaviate_api_key` mandatory which might not be desirable for all
users and connection methods (for example weaviate also support Embedded
Weaviate which I am happy to add support to here if people think it's
desirable). I wrapped the fetching of the api key into a try catch in
order to allow the `weaviate_api_key` to be unspecified. Do let me know
if this is unsatisfactory.
## Test Plan
added test for `add_texts` method.
This notebook showcases how to implement a multi-agent simulation
without a fixed schedule for who speaks when. Instead the agents decide
for themselves who speaks. We can implement this by having each agent
bid to speak. Whichever agent's bid is the highest gets to speak.
We will show how to do this in the example below that showcases a
fictitious presidential debate.
It makes sense to use `arxiv` as another source of the documents for
downloading.
- Added the `arxiv` document_loader, based on the
`utilities/arxiv.py:ArxivAPIWrapper`
- added tests
- added an example notebook
- sorted `__all__` in `__init__.py` (otherwise it is hard to find a
class in the very long list)
Tools for Bing, DDG and Google weren't consistent even though the
underlying implementations were.
All three services now have the same tools and implementations to easily
switch and experiment when building chains.

One of our users noticed a bug when calling streaming models. This is
because those models return an iterator. So, I've updated the Replicate
`_call` code to join together the output. The other advantage of this
fix is that if you requested multiple outputs you would get them all –
previously I was just returning output[0].
I also adjusted the demo docs to use dolly, because we're featuring that
model right now and it's always hot, so people won't have to wait for
the model to boot up.
The error that this fixes:

- added a few missing annotation for complex local variables.
- auto formatted.
- I also went through all other files in agent directory. no seeing any
other missing piece. (there are several prompt strings not annotated,
but I think it’s trivial. Also adding annotation will make it harder to
read in terms of indents.) Anyway, I think this is the last PR in
agent/annotation.
The sentence transformers was a dup of the HF one.
This is a breaking change (model_name vs. model) for anyone using

than doing a wrapper.
This notebook shows how the DialogueAgent and DialogueSimulator class
make it easy to extend the [Two-Player Dungeons & Dragons
example](https://python.langchain.com/en/latest/use_cases/agent_simulations/two_player_dnd.html)
to multiple players.
The main difference between simulating two players and multiple players
is in revising the schedule for when each agent speaks
To this end, we augment DialogueSimulator to take in a custom function
that determines the schedule of which agent speaks. In the example
below, each character speaks in round-robin fashion, with the
storyteller interleaved between each player.
Often an LLM will output a requests tool input argument surrounded by
single quotes. This triggers an exception in the requests library. Here,
we add a simple clean url function that strips any leading and trailing
single and double quotes before passing the URL to the underlying
requests library.

I would like to contribute with a jupyter notebook example
implementation of an AI Sales Agent using `langchain`.
The bot understands the conversation stage (you can define your own
stages fitting your needs)
using two chains:
1. StageAnalyzerChain - takes context and LLM decides what part of sales
conversation is one in
2. SalesConversationChain - generate next message

Simplifies the [Two Agent
D&D](https://python.langchain.com/en/latest/use_cases/agent_simulations/two_player_dnd.html)
example with a cleaner, simpler interface that is extensible for
multiple agents.
`DialogueAgent`:
- `send()`: applies the chatmodel to the message history and returns the
message string
- `receive(name, message)`: adds the `message` spoken by `name` to
message history
The `DialogueSimulator` class takes a list of agents. At each step, it
performs the following:
1. Select the next speaker
2. Calls the next speaker to send a message
3. Broadcasts the message to all other agents
4. Update the step counter.
The selection of the next speaker can be implemented as any function,
but in this case we simply loop through the agents.

Test for #3434 @eavanvalkenburg
Initially, I was unaware and had submitted a pull request #3450 for the
same purpose, but I have now repurposed the one I used for that. And it
worked.
Improved `arxiv/tool.py` by adding more specific information to the

Improved `arxiv.ipynb` with more useful descriptions.
In this notebook, we show how we can use concepts from

agents.
Apart from being unnecessary, postgresql is run on its default port,
which means that the langchain-server will fail to start if there is
already a postgresql server running on the host. This is obviously less
than ideal.
(Yeah, I don't understand why "expose" is the syntax that does not
expose the ports to the host...)
Tested by running langchain-server and trying out debugging on a host
that already has postgresql bound to the port 5432.

So, this is basically fixing the same things as #1517 but for GCS.
### Problem
When loading GCS Objects with `/` in the object key (eg.
folder/some-document.txt) using `GCSFileLoader`, the objects are
downloaded into a temporary directory and saved as a file.
This errors out when the parent directory does not exist within the
temporary directory.
### What this pr does
Creates parent directories based on object key.
This also works with deeply nested keys:

My attempt at improving the `Chain`'s `Getting Started` docs and

In LLM examples, I replaced the example use case when a simpler one
(shorter LLM output) to reduce cognitive load.

At present, the method of generating `point` in qdrant is to use random
`uuid`. The problem with this approach is that even documents with the
same content will be inserted repeatedly instead of updated. Using `md5`
as the `ID` of `point` to insert text can achieve true `update or
insert`.

Updated `Getting Started` page of `Prompt Templates` to showcase more
features provided by the class. Might need some proof reading because
apparently English is not my first language.
First PR, let me know if this needs anything like unit tests,
reformatting, etc. Seemed pretty straightforward to implement. Only
hitch was that mmap needs to be disabled when loading LoRAs or else you
segfault.
This PR adds support for providing a Weaviate API Key to the VectorStore
methods `from_documents` and `from_texts`. With this addition, users can
authenticate to Weaviate and make requests to private Weaviate servers
when using these methods.
## Motivation
Currently, LangChain's VectorStore methods do not provide a way to
authenticate to Weaviate. This limits the functionality of the library
and makes it more difficult for users to take advantage of Weaviate's
features.
This PR addresses this issue by adding support for providing a Weaviate
API Key as extra parameter used in the `from_texts` method.
## Contributing Guidelines
I have read the [contributing
guidelines](72b7d76d79/.github/CONTRIBUTING.md)
and the PR code passes the following tests:
- [x] make format
- [x] make lint
- [x] make coverage
- [x] make test
Now it is hard to search for the integration points between
data_loaders, retrievers, tools, etc.
I've placed links to all groups of providers and integrations on the
`ecosystem` page.
So, it is easy to navigate between all integrations from a single
location.
### Background
Continuing to implement all the interface methods defined by the
`VectorStore` class. This PR pertains to implementation of the
`max_marginal_relevance_search_by_vector` method.
### Changes
- a `max_marginal_relevance_search_by_vector` method implementation has
been added in `weaviate.py`
- tests have been added to the the new method
- vcr cassettes have been added for the weaviate tests
### Test Plan
Added tests for the `max_marginal_relevance_search_by_vector`
implementation
### Change Safety
- [x] I have added tests to cover my changes

This PR addresses several improvements:
- Previously it was not possible to load spaces of more than 100 pages.
The `limit` was being used both as an overall page limit *and* as a per
request pagination limit. This, in combination with the fact that
atlassian seem to use a server-side hard limit of 100 when page content
is expanded, meant it wasn't possible to download >100 pages. Now
`limit` is used *only* as a per-request pagination limit and `max_pages`
is introduced as the way to limit the total number of pages returned by
the paginator.
- Document metadata now includes `source` (the source url), making it
compatible with `RetrievalQAWithSourcesChain`.
- It is now possible to include inline and footer comments.
- It is now possible to pass `verify_ssl=False` and other parameters to
the confluence object for use cases that require it.
Small improvements for the YouTube loader:
a) use the YouTube API permission scope instead of Google Drive
b) bugfix: allow transcript loading for single videos
c) an additional parameter "continue_on_failure" for cases when videos

d) support automated translation for all languages, if available.

Currently `langchain.tools.sql_database.tool.QueryCheckerTool` has a
field `llm` with type `BaseLLM`. This breaks initialization for some
LLMs. For example, trying to use it with GPT4:
```python
from langchain.sql_database import SQLDatabase
from langchain.chat_models import ChatOpenAI
from langchain.tools.sql_database.tool import QueryCheckerTool
db = SQLDatabase.from_uri("some_db_uri")
llm = ChatOpenAI(model_name="gpt-4")
tool = QueryCheckerTool(db=db, llm=llm)
# pydantic.error_wrappers.ValidationError: 1 validation error for QueryCheckerTool
# llm
# Can't instantiate abstract class BaseLLM with abstract methods _agenerate, _generate, _llm_type (type=type_error)
```
Seems like much of the rest of the codebase has switched from `BaseLLM`
to `BaseLanguageModel`. This PR makes the change for QueryCheckerTool as
well

This occurred when redis_url was not passed as a parameter even though a

methods in the class.

`langchain.prompts.PromptTemplate` and

{% if bar %}
You just set bar boolean variable to true
{% endif %}
"""
# Missing variable, should raise ValueError

input_variables=["bar"],
template_format="jinja2",
validate_template=True)
# Extra variable, should raise ValueError
prompt_template = PromptTemplate(template=template,
input_variables=["bar", "foo", "extra", "thing"],

Add DocumentTransformer abstraction so that in #2915 we don't have to
wrap TextSplitter and RedundantEmbeddingFilter (neither of which uses
the query) in the contextual doc compression abstractions. with this
change, doc filter (doc extractor, whatever we call it) would look
something like
```python
class BaseDocumentFilter(BaseDocumentTransformer[_RetrievedDocument], ABC):
@abstractmethod
def filter(self, documents: List[_RetrievedDocument], query: str) -> List[_RetrievedDocument]:
...
def transform_documents(self, documents: List[_RetrievedDocument], query: Optional[str] = None, **kwargs: Any) -> List[_RetrievedDocument]:
if query is None:
raise ValueError("Must pass in non-null query to DocumentFilter")
return self.filter(documents, query)

## Background
This PR fixes this error when there are special tokens when querying the
chain:
```
Encountered text corresponding to disallowed special token '<|endofprompt|>'.
If you want this text to be encoded as a special token, pass it to `allowed_special`, e.g. `allowed_special={'<|endofprompt|>', ...}`.
If you want this text to be encoded as normal text, disable the check for this token by passing `disallowed_special=(enc.special_tokens_set - {'<|endofprompt|>'})`.
To disable this check for all special tokens, pass `disallowed_special=()`.
```
Refer to the code snippet below, it breaks in the chain line.
```
chain = ConversationalRetrievalChain.from_llm(
ChatOpenAI(openai_api_key=OPENAI_API_KEY),
retriever=vectorstore.as_retriever(),
qa_prompt=prompt,
condense_question_prompt=condense_prompt,
)
answer = chain({"question": f"{question}"})
```
However `ChatOpenAI` class is not accepting `allowed_special` and
`disallowed_special` at the moment so they cannot be passed to the
`encode()` in `get_num_tokens` method to avoid the errors.
## Change

I made a couple of improvements to the Comet tracker:
* The Comet project name is configurable in various ways (code,
environment variable or file), having a default value in code meant that
users couldn't set the project name in an environment variable or in a
file.
* I added error catching when the `flush_tracker` is called in order to
avoid crashing the whole process. Instead we are gonna display a warning
or error log message (`extra={"show_traceback": True}` is an internal
convention to force the display of the traceback when using our own
logger).
I decided to add the error catching after seeing the following error in
the third example of the notebook:
```

I still need to investigate and try to fix it, it looks related to

## Use `index_id` over `app_id`
We made a major update to index + retrieve based on Metal Indexes
(instead of apps). With this change, we accept an index instead of an
app in each of our respective core apis. [More details
here](https://docs.getmetal.io/api-reference/core/indexing).
## What is this PR for:
* This PR adds a commented line of code in the documentation that shows
how someone can use the Pinecone client with an already existing
Pinecone index
* The documentation currently only shows how to create a pinecone index
from langchain documents but not how to load one that already exists
Sometimes the LLM response (generated code) tends to miss the ending
ticks "```". Therefore causing the text parsing to fail due to not
enough values to unpack.
The 2 extra `_` don't add value and can cause errors. Suggest to simply
update the `_, action, _` to just `action` then with index.
Fixes issue #3057
This pull request addresses the need to share a single `chromadb.Client`
instance across multiple instances of the `Chroma` class. By
implementing a shared client, we can maintain consistency and reduce
resource usage when multiple instances of the `Chroma` classes are
created. This is especially relevant in a web app, where having multiple
`Chroma` instances with a `persist_directory` leads to these clients not
being synced.
This PR implements this option while keeping the rest of the
architecture unchanged.
**Changes:**
1. Add a client attribute to the `Chroma` class to store the shared
`chromadb.Client` instance.
2. Modify the `from_documents` method to accept an optional client
parameter.
3. Update the `from_documents` method to use the shared client if
provided or create a new client if not provided.
Let me know if anything needs to be modified - thanks again for your
work on this incredible repo
This PR extends upon @jzluo 's PR #2748 which addressed dialect-specific
issues with SQL prompts, and adds a prompt that uses backticks for
column names when querying BigQuery. See [GoogleSQL quoted
identifiers](https://cloud.google.com/bigquery/docs/reference/standard-sql/lexical#quoted_identifiers).
Additionally, the SQL agent currently uses a generic prompt. Not sure
how best to adopt the same optional dialect-specific prompts as above,
but will consider making an issue and PR for that too. See
[langchain/agents/agent_toolkits/sql/prompt.py](langchain/agents/agent_toolkits/sql/prompt.py).

Replaced `conversation.memory.store` to
`conversation.memory.entity_store.store`
As conversation.memory.store doesn't exist and re-ran the whole file.
allows the user to catch the issue and handle it rather than failing
hard.
This happens more than you'd expect when using output parsers with
chatgpt, especially if the temp is anything but 0. Sometimes it doesn't
want to listen and just does its own thing.
Not sure what happened here but some of the file got overwritten by
#2859 which broke filtering logic.
Here is it fixed back to normal.
@hwchase17 can we expedite this if possible :-)

### Background
Continuing to implement all the interface methods defined by the
`VectorStore` class. This PR pertains to implementation of the
`max_marginal_relevance_search` method.
### Changes
- a `max_marginal_relevance_search` method implementation has been added
in `weaviate.py`
- tests have been added to the the new method
- vcr cassettes have been added for the weaviate tests
### Test Plan
Added tests for the `max_marginal_relevance_search` implementation
### Change Safety
- [x] I have added tests to cover my changes
- Modify SVMRetriever class to add an optional relevancy_threshold
- Modify SVMRetriever.get_relevant_documents method to filter out
documents with similarity scores below the relevancy threshold
- Normalized the similarities to be between 0 and 1 so the
relevancy_threshold makes more sense
- The number of results are limited to the top k documents or the
maximum number of relevant documents above the threshold, whichever is
smaller
This code will now return the top self.k results (or less, if there are
not enough results that meet the self.relevancy_threshold criteria).
The svm.LinearSVC implementation in scikit-learn is non-deterministic,
which means
SVMRetriever.from_texts(["bar", "world", "foo", "hello", "foo bar"])
could return [3 0 5 4 2 1] instead of [0 3 5 4 2 1] with a query of
"foo".
If you pass in multiple "foo" texts, the order could be different each
time. Here, we only care if the 0 is the first element, otherwise it
will offset the text and similarities.
Example:
```python
retriever = SVMRetriever.from_texts(
["foo", "bar", "world", "hello", "foo bar"],
OpenAIEmbeddings(),
k=4,
relevancy_threshold=.25
)
result = retriever.get_relevant_documents("foo")
```
yields
```python
[Document(page_content='foo', metadata={}), Document(page_content='foo bar', metadata={})]
```

re
https://github.com/hwchase17/langchain/issues/439#issuecomment-1510442791
I think it's not polite for a library to use the root logger
both of these forms are also used:
```
logger = logging.getLogger(__name__)
logger = logging.getLogger(__file__)
```
I am not sure if there is any reason behind one vs the other? (...I am
guessing maybe just contributed by different people)
it seems to me it'd be better to consistently use
`logging.getLogger(__name__)`
this makes it easier for consumers of the library to set up log
handlers, e.g. for everything with `langchain.` prefix
Use numexpr evaluate instead of the python REPL to avoid malicious code
injection.
Tested against the (limited) math dataset and got the same score as
before.
For more permissive tools (like the REPL tool itself), other approaches
ought to be provided (some combination of Sanitizer + Restricted python
+ unprivileged-docker + ...), but for a calculator tool, only
mathematical expressions should be permitted.
See https://github.com/hwchase17/langchain/issues/814
Last week I added the `PDFMinerPDFasHTMLLoader`. I am adding some
example code in the notebook to serve as a tutorial for how that loader
can be used to create snippets of a pdf that are structured within
sections. All the other loaders only provide the `Document` objects
segmented by pages but that's pretty loose given the amount of other
metadata that can be extracted.
With the new loader, one can leverage font-size of the text to decide
when a new sections starts and can segment the text more semantically as
shown in the tutorial notebook. The cell shows that we are able to find
the content of entire section under **Related Work** for the example pdf
which is spread across 2 pages and hence is stored as two separate
documents by other loaders
Fixes a bug I was seeing when the `TokenTextSplitter` was correctly
splitting text under the gpt3.5-turbo token limit, but when firing the
prompt off too openai, it'd come back with an error that we were over
the context limit.
gpt3.5-turbo and gpt-4 use `cl100k_base` tokenizer, and so the counts
are just always off with the default `gpt-2` encoder.
It's possible to pass along the encoding to the `TokenTextSplitter`, but
it's much simpler to pass the model name of the LLM. No more concern
about keeping the tokenizer and llm model in sync :)
I got the following stacktrace when the agent was trying to search

Add a method that exposes a similarity search with corresponding
normalized similarity scores. Implement only for FAISS now.
### Motivation:
Some memory definitions combine `relevance` with other scores, like
recency , importance, etc.
While many (but not all) of the `VectorStore`'s expose a
`similarity_search_with_score` method, they don't all interpret the
units of that score (depends on the distance metric and whether or not
the the embeddings are normalized).
This PR proposes a `similarity_search_with_normalized_similarities`
method that lets consumers of the vector store not have to worry about
the metric and embedding scale.
*Most providers default to euclidean distance, with Pinecone being one
exception (defaults to cosine _similarity_).*

The encoding fetch was out of date. Luckily OpenAI has a nice[
`encoding_for_model`](46287bfa49/tiktoken/model.py)
function in `tiktoken` we can use now.
Title, lang and description are on almost every web page, and are
incredibly useful pieces of information that currently isn't captured
with the current web base loader
I thought about adding the title and description to the content of the
document, as
that content could be useful in search, but I left it out for right now.
If you think
it'd be worth adding, happy to add it.
I've found it's nice to have the title/description in the metadata to
have some structured data
when retrieving rows from vectordbs for use with summary and source
citation, so if we do want to add it to the `page_content`, i'd advocate
for it to also be included in metadata.
Same as similarity_search, allows child classes to add vector
store-specific args (this was technically already happening in couple
places but now typing is correct).
Minor cosmetic changes
- Activeloop environment cred authentication in notebooks with
`getpass.getpass` (instead of CLI which not always works)
- much faster tests with Deep Lake pytest mode on
- Deep Lake kwargs pass
Notes
- I put pytest environment creds inside `vectorstores/conftest.py`, but
feel free to suggest a better location. For context, if I put in
`test_deeplake.py`, `ruff` doesn't let me to set them before import
deeplake

NOTE: for reviewers, `hide whitespace` option recommended since I
changed the indentation of an if-block to use `continue` instead so it
looks less like a Christmas tree :)
Mentioned the idea here initially:
https://github.com/hwchase17/langchain/pull/2106#issuecomment-1487509106
Since there have been dialect-specific issues, we should use
dialect-specific prompts. This way, each prompt can be separately
modified to best suit each dialect as needed. This adds a prompt for
each dialect supported in sqlalchemy (mssql, mysql, mariadb, postgres,
oracle, sqlite). For this initial implementation, the only differencse
between the prompts is the instruction for the clause to use to limit
the number of rows queried for, and the instruction for wrapping column
names using each dialect's identifier quote character.
Optimization :Limit search results when k < 10

Mendable Seach Integration is Finally here!
Hey yall,
After various requests for Mendable in Python docs, we decided to get
our hands dirty and try to implement it.
Here is a version where we implement our **floating button** that sits
on the bottom right of the screen that once triggered (via press or CMD
K) will work the same as the js langchain docs.
Super excited about this and hopefully the community will be too.
@hwchase17 will send you the admin details via dm etc. The anon_key is
fine to be public.
Let me know if you need any further customization. I added the langchain
logo to it.

Adds a loader for Slack Exports which can be a very valuable source of
knowledge to use for internal QA bots and other use cases.
```py
# Export data from your Slack Workspace first.
from langchain.document_loaders import SLackDirectoryLoader
SLACK_WORKSPACE_URL = "https://awesome.slack.com"
loader = ("Slack_Exports", SLACK_WORKSPACE_URL)
docs = loader.load()
```
My recent pull request (#2729) neglected to update the
`reduce_openapi_spec` in spec.py to also accommodate PATCH and DELETE
added to planner.py and prompt_planner.py.
Have seen questions about whether or not the `SQLDatabaseChain` supports
more than just sqlite, which was unclear in the docs, so tried to
clarify that and how to connect to other dialects.
The doc loaders index was picking up a bunch of subheadings because I
mistakenly made the MD titles H1s. Fixed that.
also the easy minor warnings from docs_build
I was testing out the WhatsApp Document loader, and noticed that
sometimes the date is of the following format (notice the additional
underscore):
```
3/24/23, 1:54_PM - +91 99999 99999 joined using this group's invite link
3/24/23, 6:29_PM - +91 99999 99999: When are we starting then?
```
Wierdly, the underscore is visible in Vim, but not on editors like
VSCode. I presume it is some unusual character/line terminator.
Nevertheless, I think handling this edge case will make the document
loader more robust.

### Summary
Adds support for processing non HTML document types in the URL loader.
For example, the URL loader can now process a PDF or markdown files
hosted at a URL.
### Testing
```python
from langchain.document_loaders import UnstructuredURLLoader
urls = ["https://www.understandingwar.org/sites/default/files/Russian%20Offensive%20Campaign%20Assessment%2C%20April%2011%2C%202023.pdf"]
loader = UnstructuredURLLoader(urls=urls, strategy="fast")
docs = loader.load()
print(docs[0].page_content[:1000])
```
Updated the "load_memory_variables" function of the
ConversationBufferWindowMemory to support a window size of 0 (k=0).
Previous behavior would return the full memory instead of an empty
array.
Eval chain is currently very sensitive to differences in phrasing,
punctuation, and tangential information. This prompt has worked better
for me on my examples.
More general q: Do we have any framework for evaluating default prompt
changes? Could maybe start doing some regression testing?
Currently, the output type of a number of OutputParser's `parse` methods
is `Any` when it can in fact be inferred.
This PR makes BaseOutputParser use a generic type and fixes the output
types of the following parsers:
- `PydanticOutputParser`
- `OutputFixingParser`
- `RetryOutputParser`
- `RetryWithErrorOutputParser`
The output of the `StructuredOutputParser` is corrected from `BaseModel`
to `Any` since there are no type guarantees provided by the parser.
Fixes issue #2715

**Problem:**
The `from_documents` method in Qdrant vectorstore is unnecessary because
it does not change any default behavior from the abstract base class
method of `from_documents` (contrast this with the method in Chroma
which makes a change from default and turns `embeddings` into an
Optional parameter).
Also, the docstrings need some cleanup.
**Solution:**
Remove unnecessary method and improve docstrings.

This change allows the user to initialize the ZapierNLAWrapper with a
valid Zapier NLA OAuth Access_Token, which would be used to make
requests back to the Zapier NLA API.
When a `zapier_nla_oauth_access_token` is passed to the ZapierNLAWrapper
it is no longer required for the `ZAPIER_NLA_API_KEY ` environment
variable to be set, still having it set will not affect the behavior as
the `zapier_nla_oauth_access_token` will be used over the
`ZAPIER_NLA_API_KEY`
Currently, the function still fails if `continue_on_failure` is set to
True, because `elements` is not set.

Add more missed imports for integration tests. Bump `pytest` to the

Related PR: https://github.com/hwchase17/langchain/pull/2560
Avoid using placeholder methods that only perform a `cast()`
operation because the typing would otherwise be inferred to be the
parent `VectorStore` class. This is unnecessary with TypeVar's.
This PR proposes an update to the OpenAPI Planner and Planner Prompts to
make Patch and Delete available to the planner and executor. I followed
the same patterns as for GET and POST, and made some updates to the
examples available to the Planner and Orchestrator.
Of note, I tried to write prompts for DELETE such that the model will
only execute that job if the User specifically asks for a 'Delete' (see
the Prompt_planner.py examples to see specificity), or if the User had
previously authorized the Delete in the Conversation memory. Although
PATCH also modifies existing data, I considered it lower risk and so did
not try to enforce the same restrictions on the Planner.
When using the llama.cpp together with agent like
zero-shot-react-description, the missing branch will cause the parameter
`stop` left empty, resulting in unexpected output format from the model.
This patch fixes that issue.
I fixed an issue where an error would always occur when making a request
using the `TextRequestsWrapper` with async API.
This is caused by escaping the scope of the context, which causes the
connection to be broken when reading the response body.
The correct usage is as described in the [official
tutorial](https://docs.aiohttp.org/en/stable/client_quickstart.html#make-a-request),
where the text method must also be handled in the context scope.

This PR adds a LangChain implementation of CAMEL role-playing example:
https://github.com/lightaime/camel.
I am sorry that I am not that familiar with LangChain. So I only
implement it in a naive way. There may be a better way to implement it.

Hi,
just wanted to mention that I added `langchain` to
[conda-forge](https://github.com/conda-forge/langchain-feedstock), so
that it can be installed with `conda`/`mamba` etc.
This makes it available to some corporate users with custom
conda-servers and people who like to manage their python envs with
conda.
**Problem:**
OpenAI Embeddings has a few minor issues: method name and comment for
_completion_with_retry seems to be a copypasta error and a few comments
around usage of embedding_ctx_length seem to be incorrect.
**Solution:**
Clean up issues.

Took me a bit to find the proper places to get the API keys. The link
earlier provided to setup search is still good, but why not provide
direct link to the Google cloud tools that give you ability to create
keys?
`combine_docs` does not go through the standard chain call path which
means that chain callbacks won't be triggered, meaning QA chains won't
be traced properly, this fixes that.
Also fix several errors in the chat_vector_db notebook
Adds a new pdf loader using the existing dependency on PDFMiner.
The new loader can be helpful for chunking texts semantically into
sections as the output html content can be parsed via `BeautifulSoup` to
get more structured and rich information about font size, page numbers,
pdf headers/footers, etc. which may not be available otherwise with
other pdf loaders
Improvements to Deep Lake Vector Store
- much faster view loading of embeddings after filters with
`fetch_chunks=True`
- 2x faster ingestion
- use np.float32 for embeddings to save 2x storage, LZ4 compression for
text and metadata storage (saves up to 4x storage for text data)
- user defined functions as filters
Docs
- Added retriever full example for analyzing twitter the-algorithm
source code with GPT4
- Added a use case for code analysis (please let us know your thoughts
how we can improve it)

RWKV is an RNN with a hidden state that is part of its inference.
However, the model state should not be carried across uses and it's a

Almost all integration tests have failed, but we haven't encountered any

fix https://github.com/hwchase17/langchain/issues/2426
Using `pytest-vcr` in integration tests has several benefits. Firstly,
it removes the need to mock external services, as VCR records and
replays HTTP interactions on the fly. Secondly, it simplifies the
integration test setup by eliminating the need to set up and tear down
external services in some cases. Finally, it allows for more reliable
and deterministic integration tests by ensuring that HTTP interactions
are always replayed with the same response.
Overall, `pytest-vcr` is a valuable tool for simplifying integration
test setup and improving their reliability
This commit adds the `pytest-vcr` package as a dependency for
integration tests in the `pyproject.toml` file. It also introduces two
new fixtures in `tests/integration_tests/conftest.py` files for managing
cassette directories and VCR configurations.
In addition, the
`tests/integration_tests/vectorstores/test_elasticsearch.py` file has
been updated to use the `@pytest.mark.vcr` decorator for recording and
replaying HTTP interactions.
Finally, this commit removes the `documents` fixture from the
`test_elasticsearch.py` file and replaces it with a new fixture defined
in `tests/integration_tests/vectorstores/conftest.py` that yields a list
of documents to use in any other tests.
This also includes my second attempt to fix issue :

I noticed that the value of get_num_tokens_from_messages in `ChatOpenAI`
is always one less than the response from OpenAI's API. Upon checking
the official documentation, I found that it had been updated, so I made
the necessary corrections.
Then now I got the same value from OpenAI's API.

Right now, eval chains require an answer for every question. It's
cumbersome to collect this ground truth so getting around this issue
with 2 things:
* Adding a context param in `ContextQAEvalChain` and simply evaluating
if the question is answered accurately from context
* Adding chain of though explanation prompting to improve the accuracy
of this w/o GT.
This also gets to feature parity with openai/evals which has the same
contextual eval w/o GT.
TODO in follow-up:
* Better prompt inheritance. No need for seperate prompt for CoT
reasoning. How can we merge them together

#991 has already implemented this convenient feature to prevent
exceeding max token limit in embedding model.
> By default, this function is deactivated so as not to change the
previous behavior. If you specify something like 8191 here, it will work
as desired.
According to the author, this is not set by default.
Until now, the default model in OpenAIEmbeddings's max token size is
8191 tokens, no other openai model has a larger token limit.
So I believe it will be better to set this as default value, other wise
users may encounter this error and hard to solve it.
Add support for defining the organization of OpenAI, similarly to what
is done in the reference code below:
```
import os
import openai
openai.organization = os.getenv("OPENAI_ORGANIZATION")
openai.api_key = os.getenv("OPENAI_API_KEY")
```
Evaluation so far has shown that agents do a reasonable job of emitting
`json` blocks as arguments when cued (instead of typescript), and `json`
permits the `strict=False` flag to permit control characters, which are
likely to appear in the response in particular.
This PR makes this change to the request and response synthesizer
chains, and fixes the temperature to the OpenAI agent in the eval
notebook. It also adds a `raise_error = False` flag in the notebook to
facilitate debugging
This still doesn't handle the following
- non-JSON media types
- anyOf, allOf, oneOf's
And doesn't emit the typescript definitions for referred types yet, but
that can be saved for a separate PR.
Also, we could have better support for Swagger 2.0 specs and OpenAPI
3.0.3 (can use the same lib for the latter) recommend offline conversion
for now.
`AgentExecutor` already has support for limiting the number of
iterations. But the amount of time taken for each iteration can vary
quite a bit, so it is difficult to place limits on the execution time.
This PR adds a new field `max_execution_time` to the `AgentExecutor`
model. When called asynchronously, the agent loop is wrapped in an
`asyncio.timeout()` context which triggers the early stopping response
if the time limit is reached. When called synchronously, the agent loop
checks for both the max_iteration limit and the time limit after each
iteration.
When used asynchronously `max_execution_time` gives really tight control
over the max time for an execution chain. When used synchronously, the
chain can unfortunately exceed max_execution_time, but it still gives
more control than trying to estimate the number of max_iterations needed
to cap the execution time.

### Summary
#1667 updated several Unstructured loaders to accept
`unstructured_kwargs` in the `__init__` function. However, the previous
PR did not add this functionality to every Unstructured loader. This PR
ensures `unstructured_kwargs` are passed in all remaining Unstructured
loaders.
### Summary
Adds support for MSFT Outlook emails saved in `.msg` format to
`UnstructuredEmailLoader`. Works if the user has `unstructured>=0.5.8`
installed.
### Testing
The following tests use the example files under `example-docs` in the
Unstructured repo.
```python
from langchain.document_loaders import UnstructuredEmailLoader
loader = UnstructuredEmailLoader("fake-email.eml")
loader.load()
loader = UnstructuredEmailLoader("fake-email.msg")
loader.load()
```
It's useful to evaluate API Chains against a mock server. This PR makes
an example "robot" server that exposes endpoints for the following:
- Path, Query, and Request Body argument passing
- GET, PUT, and DELETE endpoints exposed OpenAPI spec.

if you'd like
It's helpful for developers to run the linter locally on just the

This PR adds support for a `lint_diff` command.
Ruff is still run over the entire directory since it's very fast.
- Create a new docker-compose file to start an Elasticsearch instance
for integration tests.
- Add new tests to `test_elasticsearch.py` to verify Elasticsearch
functionality.
- Include an optional group `test_integration` in the `pyproject.toml`
file. This group should contain dependencies for integration tests and
can be installed using the command `poetry install --with
test_integration`. Any new dependencies should be added by running
`poetry add some_new_deps --group "test_integration" `
Note:
New tests running in live mode, which involve end-to-end testing of the
OpenAI API. In the future, adding `pytest-vcr` to record and replay all
API requests would be a nice feature for testing process.More info:

In the case no pinecone index is specified, or a wrong one is, do not
create a new one. Creating new indexes can cause unexpected costs to
users, and some code paths could cause a new one to be created on each
invocation.
This PR solves #2413.
Add `n_batch` and `last_n_tokens_size` parameters to the LlamaCpp class.
These parameters (epecially `n_batch`) significantly effect performance.
There's also a `verbose` flag that prints system timings on the `Llama`
class but I wasn't sure where to add this as it conflicts with (should
be pulled from?) the LLM base class.
The specs used in chat-gpt plugins have only a few endpoints and have
unrealistically small specifications. By contrast, a spec like spotify's
has 60+ endpoints and is comprised 100k+ tokens.
Here are some impressive traces from gpt-4 that string together
non-trivial sequences of API calls. As noted in `planner.py`, gpt-3 is
not as robust but can be improved with i) better retry, self-reflect,
etc. logic and ii) better few-shots iii) etc. This PR's just a first
attempt probing a few different directions that eventually can be made
more core.

This PR updates Qdrant to 1.1.1 and introduces local mode, so there is
no need to spin up the Qdrant server. By that occasion, the Qdrant
example notebooks also got updated, covering more cases and answering
some commonly asked questions. All the Qdrant's integration tests were
switched to local mode, so no Docker container is required to launch
them.
Update the Dockerfile to use the `$POETRY_HOME` argument to set the
Poetry home directory instead of adding Poetry to the PATH environment
variable.
Add instructions to the `CONTRIBUTING.md` file on how to run tests with
Docker.
Closes https://github.com/hwchase17/langchain/issues/2324
This pull request adds an enum class for the various types of agents
used in the project, located in the `agent_types.py` file. Currently,
the project is using hardcoded strings for the initialization of these
agents, which can lead to errors and make the code harder to maintain.
With the introduction of the new enums, the code will be more readable
and less error-prone.
The new enum members include:
- ZERO_SHOT_REACT_DESCRIPTION
- REACT_DOCSTORE
- SELF_ASK_WITH_SEARCH
- CONVERSATIONAL_REACT_DESCRIPTION
- CHAT_ZERO_SHOT_REACT_DESCRIPTION
- CHAT_CONVERSATIONAL_REACT_DESCRIPTION
In this PR, I have also replaced the hardcoded strings with the
appropriate enum members throughout the codebase, ensuring a smooth
transition to the new approach.
Currently, `agent_toolkits.sql.create_sql_agent()` passes kwargs to the
`ZeroShotAgent` that it creates but not to `AgentExecutor` that it also
creates. This prevents the caller from providing some useful arguments
like `max_iterations` and `early_stopping_method`
This PR changes `create_sql_agent` so that it passes kwargs to both
constructors.

### Motivation / Context
When exploring `load_tools(["requests"] )`, I would have expected all
request method tools to be imported instead of just `RequestsGetTool`.
### Changes
Break `_get_requests` into multiple functions by request method. Each
function returns the `BaseTool` for that particular request method.
In `load_tools`, if the tool name "requests_all" is encountered, we
replace with all `_BASE_TOOLS` that starts with `requests_`.
This way, `load_tools(["requests"])` returns:
- RequestsGetTool
- RequestsPostTool
- RequestsPatchTool
- RequestsPutTool
- RequestsDeleteTool
Hello!
I've noticed a bug in `create_pandas_dataframe_agent`. When calling it
with argument `return_intermediate_steps=True`, it doesn't return the
intermediate step. I think the issue is that `kwargs` was not passed
where it needed to be passed. It should be passed into
`AgentExecutor.from_agent_and_tools`
Please correct me if my solution isn't appropriate and I will fix with
the appropriate approach.

`persist()` is required even if it's invoked in a script.
Without this, an error is thrown:
```
chromadb.errors.NoIndexException: Index is not initialized
```
This changes addresses two issues.
First, we add `setuptools` to the dev dependencies in order to debug
tests locally with an IDE, especially with PyCharm. All dependencies dev
dependencies should be installed with `poetry install --extras "dev"`.
Second, we use PurePosixPath instead of Path for URL paths to fix issues
with testing in Windows. This ensures that forward slashes are used as
the path separator regardless of the operating system.

This PR fixes a logic error in the Redis VectorStore class
Creating a redis vector store `from_texts` creates 1:1 mapping between
the object and its respected index, created in the function. The index
will index only documents adhering to the `doc:{index_name}` prefix.
Calling `add_texts` should use the same prefix, unless stated otherwise
in `keys` dictionary, and not create a new random uuid.
### Summary
This PR introduces a `SeleniumURLLoader` which, similar to
`UnstructuredURLLoader`, loads data from URLs. However, it utilizes
`selenium` to fetch page content, enabling it to work with
JavaScript-rendered pages. The `unstructured` library is also employed
for loading the HTML content.
### Testing
```bash
pip install selenium
pip install unstructured
```
```python
from langchain.document_loaders import SeleniumURLLoader
urls = [
"https://www.youtube.com/watch?v=dQw4w9WgXcQ",
"https://goo.gl/maps/NDSHwePEyaHMFGwh8"
]
loader = SeleniumURLLoader(urls=urls)
data = loader.load()

and added output.

**Context**
Noticed a TODO in `langchain/vectorstores/elastic_vector_search.py` for
adding the option to NOT refresh ES indices
**Change**
Added a param to `add_texts()` called `refresh_indices` to not refresh
ES indices. The default value is `True` so that existing behavior does
not break.
Solves #2247. Noted that the only test I added checks for the
BeautifulSoup behaviour change. Happy to add a test for
`DirectoryLoader` if deemed necessary.
This makes it easy to run the tests locally. Some tests may not be able
to run in `Windows` environments, hence the need for a `Dockerfile`.
The new `Dockerfile` sets up a multi-stage build to install Poetry and
dependencies, and then copies the project code to a final image for
tests.
The `Makefile` has been updated to include a new 'docker_tests' target
that builds the Docker image and runs the `unit tests` inside a
container.
It would be beneficial to offer a local testing environment for
developers by enabling them to run a Docker image on their local
machines with the required dependencies, particularly for integration
tests. While this is not included in the current PR, it would be
straightforward to add in the future.
This pull request lacks documentation of the changes made at this
moment.
I'm using Deeplake as a vector store for a Q&A application. When several
questions are being processed at the same time for the same dataset, the
2nd one triggers the following error:
> LockedException: This dataset cannot be open for writing as it is
locked by another machine. Try loading the dataset with
`read_only=True`.
Answering questions doesn't require writing new embeddings so it's ok to
open the dataset in read only mode at that time.
This pull request thus adds the `read_only` option to the Deeplake
constructor and to its subsequent `deeplake.load()` call.
The related Deeplake documentation is
[here](https://docs.deeplake.ai/en/latest/deeplake.html#deeplake.load).
I've tested this update on my local dev environment. I don't know if an
integration test and/or additional documentation are expected however.
Let me know if it is, ideally with some guidance as I'm not particularly
experienced in Python.
This merge request proposes changes to the TextLoader class to make it
more flexible and robust when handling text files with different
encodings. The current implementation of TextLoader does not provide a
way to specify the encoding of the text file being read. As a result, it
might lead to incorrect handling of files with non-default encodings,
causing issues with loading the content.
Benefits:
- The proposed changes will make the TextLoader class more flexible,
allowing it to handle text files with different encodings.
- The changes maintain backward compatibility, as the encoding parameter
is optional.
# What does this PR do?
This PR adds the `__version__` variable in the main `__init__.py` to
easily retrieve the version, e.g., for debugging purposes or when a user
wants to open an issue and provide information.
Usage
```python
>>> import langchain
>>> langchain.__version__
'0.0.127'
```
When downloading a google doc, if the document is not a google doc type,
for example if you uploaded a .DOCX file to your google drive, the error
you get is not informative at all. I added a error handler which print
the exact error occurred during downloading the document from google
docs.
### Summary
Adds a new document loader for processing e-publications. Works with
`unstructured>=0.5.4`. You need to have
[`pandoc`](https://pandoc.org/installing.html) installed for this loader
to work.
### Testing
```python
from langchain.document_loaders import UnstructuredEPubLoader
loader = UnstructuredEPubLoader("winter-sports.epub", mode="elements")
data = loader.load()
data[0]
```
This upsteam wikipedia page loading seems to still have issues. Finding
a compromise solution where it does an exact match search and not a
search for the completion.
See previous PR: https://github.com/hwchase17/langchain/pull/2169
Creating a page using the title causes a wikipedia search with
autocomplete set to true. This frequently causes the summaries to be
unrelated to the actual page found.
See:
1554943e8a/wikipedia/wikipedia.py (L254-L280)
`predict_and_parse` exists, and it's a nice abstraction to allow for
applying output parsers to LLM generations. And async is very useful.
As an aside, the difference between `call/acall`, `predict/apredict` and
`generate/agenerate` isn't entirely
clear to me other than they all call into the LLM in slightly different
ways.
Is there some documentation or a good way to think about these
differences?
One thought:
output parsers should just work magically for all those LLM calls. If
the `output_parser` arg is set on the prompt, the LLM has access, so it
seems like extra work on the user's end to have to call
`output_parser.parse`
If this sounds reasonable, happy to throw something together. @hwchase17
- Current docs are pointing to the wrong module, fixed
- Added some explanation on how to find the necessary parameters
- Added chat-based codegen example w/ retrievers

example was too heavy for the page or not but decided "hey, I probably
would want to see it" and so included it.

The new functionality of Redis backend for chat message history
([see](https://github.com/hwchase17/langchain/pull/2122)) uses the Redis
list object to store messages and then uses the `lrange()` to retrieve
the list of messages
([see](https://github.com/hwchase17/langchain/blob/master/langchain/memory/chat_message_histories/redis.py#L50)).
Unfortunately this retrieves the messages as a list sorted in the
opposite order of how they were inserted - meaning the last inserted
message will be first in the retrieved list - which is not what we want.
This PR fixes that as it changes the order to match the order of
insertion.
Currently, if a tool is set to verbose, an agent can override it by
passing in its own verbose flag. This is not ideal if we want to stream
back responses from agents, as we want the llm and tools to be sending
back events but nothing else. This also makes the behavior consistent
with ts.
This merge includes updated comments in the ElasticVectorSearch class to
provide information on how to connect to `Elasticsearch` instances that
require login credentials, including Elastic Cloud, without any
functional changes.
The `ElasticVectorSearch` class now inherits from the `ABC` abstract
base class, which does not break or change any functionality. This
allows for easy subclassing and creation of custom implementations in
the future or for any users, especially for me 😄
I confirm that before pushing these changes, I ran:
```bash
make format && make lint
```
To ensure that the new documentation is rendered correctly I ran
```bash
make docs_build
```
To ensure that the new documentation has no broken links, I ran a check
```bash
make docs_linkcheck
```
Also take a look at https://github.com/hwchase17/langchain/issues/1865
P.S. Sorry for spamming you with force-pushes. In the future, I will be
smarter.

Currently only google documents and pdfs can be loaded from google
drive. This PR implements the latest recommended method for getting
google sheets including all tabs.
It currently parses the google sheet data the exact same way as the csv
loader - the only difference is that the gdrive sheets loader is not
using the `csv` library since the data is already in a list.
I've found it useful to track the number of successful requests to
OpenAI. This gives me a better sense of the efficiency of my prompts and
helps compare map_reduce/refine on a cheaper model vs. stuffing on a
more expensive model with higher capacity.
Loading this sitemap didn't work for me
https://www.alzallies.com/sitemap.xml
Changing this fixed it and it seems like a good idea to do it in
general.
Integration tests pass
Fix the issue outlined in #1712 to ensure the `BaseQAWithSourcesChain`
can properly separate the sources from an agent response even when they
are delineated by a newline.
This will ensure the `BaseQAWithSourcesChain` can reliably handle both
of these agent outputs:
* `"This Agreement is governed by English law.\nSOURCES: 28-pl"` ->
`"This Agreement is governed by English law.\n`, `"28-pl"`
* `"This Agreement is governed by English law.\nSOURCES:\n28-pl"` ->
`"This Agreement is governed by English law.\n`, `"28-pl"`
I couldn't find any unit tests for this but please let me know if you'd
like me to add any test coverage.
1. Removed the `summaries` dictionary in favor of directly appending to
the summary_strings list, which avoids the unnecessary double-loop.
2. Simplified the logic for populating the `context` variable.
Co-created with GPT-4 @agihouse
This worked for me, but I'm not sure if its the right way to approach
something like this, so I'm open to suggestions.
Adds class properties `reduce_k_below_max_tokens: bool` and
`max_tokens_limit: int` to the `ConversationalRetrievalChain`. The code
is basically copied from
[`RetreivalQAWithSourcesChain`](46d141c6cb/langchain/chains/qa_with_sources/retrieval.py (L24))
Seems like a copy paste error. The very next example does have this
line.
Please tell me if I missed something in the process and should have
created an issue or something first!
the j1-* models are marked as [Legacy] in the docs and are expected to

This PR adds Notion DB loader for langchain.
It reads content from pages within a Notion Database. It uses the Notion
API to query the database and read the pages. It also reads the metadata
from the pages and stores it in the Document object.
This is useful if you rely on the `on_tool_end` callback to detect which
tool has finished in a multi agents scenario.
For example, I'm working on a project where I consume the `on_tool_end`
event where the event could be emitted by many agents or tools. Right
now the only way to know which tool has finished would be set a marker
on the `on_tool_start` and catch it on `on_tool_end`.
I didn't want to break the signature of the function, but what would
have been cleaner would be to pass the same details as in
`on_tool_start`

seems linkchecker isn't catching them because it runs on generated html.
at that point the links are already missing.
the generation process seems to strip invalid references when they can't
be re-written from md to html.
I used https://github.com/tcort/markdown-link-check to check the doc
source directly.
There are a few false positives on localhost for development.
I have found that when the user has not asked an explicit question the
agent might have trouble answering the latest comment and might instead
try to answer a question that came before in the conversation which
would not be what is desired.
I also found that the agent might get confused with the current prompt
and talk about the tools themselves instead of the results obtained from
them.
I added two changes to the tool prompt so that the agent answers only
the last comment/question and only returns information from tool
results.

I noticed that the "getting started" guide section on agents included an
example test where the agent was getting the question wrong 😅
I guess Olivia Wilde's dating life is too tough to keep track of for
this simple agent example. Let's change it to something a little easier,
so users who are running their agent for the first time are less likely
to be confused by a result that doesn't match that which is on the docs.

Ran into a broken build if bs4 wasn't installed in the project.
Minor tweak to follow the other doc loaders optional package-loading
conventions.
Also updated html docs to include reference to this new html loader.
side note: Should there be 2 different html-to-text document loaders?
This new one only handles local files, while the existing unstructured
html loader handles HTML from local and remote. So it seems like the
improvement was adding the title to the metadata, which is useful but
could also be added to `html.py`
Fixed a typo in the argument of the query method within the
VectorStoreIndexWrapper class. Specifically, the argument `retriver` has
been changed to `retriever`. With this correction, the correct argument
name is used, and potential bugs are avoided.

Technically a duplicate fix to #1619 but with unit tests and a small
documentation update
- Propagate `filter` arg in Chroma `similarity_search` to delegated call
to `similarity_search_with_score`
- Add `filter` arg to `similarity_search_by_vector`
- Clarify doc strings on FakeEmbeddings
In https://github.com/hwchase17/langchain/issues/1716 , it was
identified that there were two .py files performing similar tasks. As a
resolution, one of the files has been removed, as its purpose had
already been fulfilled by the other file. Additionally, the init has
been updated accordingly.
Furthermore, the how_to_guides.rst file has been updated to include
links to documentation that was previously missing. This was deemed
necessary as the existing list on
https://langchain.readthedocs.io/en/latest/modules/document_loaders/how_to_guides.html
was incomplete, causing confusion for users who rely on the full list of
documentation on the left sidebar of the website.
In the langchain.vectorstores.opensearch_vector_search.py, in the
add_texts function, around line 247, we have the following code
```python
embeddings = [
self.embedding_function.embed_documents(list(text))[0] for text in texts
]
```
the goal of the `list(text)` part I believe is to pass a list to the
embed_documents list instead of a a str. However, `list(text)` is a
subtle bug
`list(text)` would convert the string text into an array, where each
element of the array is a character of the string

The correct way should be to change the code to
```python
embeddings = [
self.embedding_function.embed_documents([text])[0] for text in texts
]
```
Which wraps the string inside a list.
The `CollectionStore` for `PGVector` has a `cmetadata` field but it's
never used. This PR add the ability to save metadata information to the

The GPT Index project is transitioning to the new project name,
LlamaIndex.
I've updated a few files referencing the old project name and repository
URL to the current ones.
From the [LlamaIndex repo](https://github.com/jerryjliu/llama_index):
> NOTE: We are rebranding GPT Index as LlamaIndex! We will carry out
this transition gradually.
>
> 2/25/2023: By default, our docs/notebooks/instructions now reference
"LlamaIndex" instead of "GPT Index".
>
> 2/19/2023: By default, our docs/notebooks/instructions now use the
llama-index package. However the gpt-index package still exists as a
duplicate!
>
> 2/16/2023: We have a duplicate llama-index pip package. Simply replace
all imports of gpt_index with llama_index if you choose to pip install
llama-index.
I'm not associated with LlamaIndex in any way. I just noticed the
discrepancy when studying the lanchain documentation.
# What does this PR do?
This PR adds similar to `llms` a SageMaker-powered `embeddings` class.
This is helpful if you want to leverage Hugging Face models on SageMaker
for creating your indexes.
I added a example into the
[docs/modules/indexes/examples/embeddings.ipynb](https://github.com/hwchase17/langchain/compare/master...philschmid:add-sm-embeddings?expand=1#diff-e82629e2894974ec87856aedd769d4bdfe400314b03734f32bee5990bc7e8062)
document. The example currently includes some `_### TEMPORARY: Showing
how to deploy a SageMaker Endpoint from a Hugging Face model ###_ ` code
showing how you can deploy a sentence-transformers to SageMaker and then
run the methods of the embeddings class.
@hwchase17 please let me know if/when i should remove the `_###
TEMPORARY: Showing how to deploy a SageMaker Endpoint from a Hugging
Face model ###_` in the description i linked to a detail blog on how to
deploy a Sentence Transformers so i think we don't need to include those
steps here.
I also reused the `ContentHandlerBase` from
`langchain.llms.sagemaker_endpoint` and changed the output type to `any`
since it is depending on the implementation.
I was getting the same issue reported in #1339 by
[MacYang555](https://github.com/MacYang555) when running the test suite
on my Mac. I implemented the fix they suggested to use a regex match in
the output assertion for the scenario under test.
Resolves#1339
Use the following code to test:
```python
import os
from langchain.llms import OpenAI
from langchain.chains.api import podcast_docs
from langchain.chains import APIChain
# Get api key here: https://openai.com/pricing
os.environ["OPENAI_API_KEY"] = "sk-xxxxx"
# Get api key here: https://www.listennotes.com/api/pricing/
listen_api_key = 'xxx'
llm = OpenAI(temperature=0)
headers = {"X-ListenAPI-Key": listen_api_key}
chain = APIChain.from_llm_and_api_docs(llm, podcast_docs.PODCAST_DOCS, headers=headers, verbose=True)
chain.run("Search for 'silicon valley bank' podcast episodes, audio length is more than 30 minutes, return only 1 results")
```
Known issues: the api response data might be too big, and we'll get such
error:
`openai.error.InvalidRequestError: This model's maximum context length
is 4097 tokens, however you requested 6733 tokens (6477 in your prompt;
256 for the completion). Please reduce your prompt; or completion
length.`
When following the Quick Start instructions in the contributing docs, I
was getting a "WheelFileValidationError" on installation of debugpy
which was blocking the installation of a number of other deps. Google
turned up this [GitHub
issue](https://github.com/microsoft/debugpy/issues/1246) indicating a
regression in Poetry 1.4.1 and workarounds.
This PR updates the contrib docs noting the issue and the workarounds.
From Robert "Right now the dynamic/ route for specifically the above
endpoints is acting on all providers a user has set up, not just the
provider for the supplied API key."
While it might be a bit more restrictive, I find that using the
Embedding interface as an input for the vector store creation is better
than an embedding function because we can use bulk requests and possibly
the retry logic if needed.
I have seen that some vector store implementations use Embedding while
others use embedding function so I don't know what is the criteria to
have one or the other, in my opinion they should all just be Embedding
or have a way more complex embedding function that accepts multiple
texts instead of one by one.

Regarding [this
issue](https://github.com/hwchase17/langchain/issues/1754),
`BasePromptTample` class docstring is a little outdated, thus it
requires new method `format_prompt` for now.
As such, I have made some modifications to the docstring to bring it up
to date.
I tried to adhere to the established document style, and would
appreciate you for taking a look at this PR.
Fix#1756
Use the `namespace` argument of `Pinecone.from_exisiting_index` to set
the default value of `namespace` for other methods. Leads to more
expected behavior and easier integration in chains.
For the test, I've added a line to delete and rebuild the
`langchain-demo` index at the beginning of the test. I'm not 100% sure
if it's a good idea but it makes the test reproducible.
New to Langchain, was a bit confused where I should find the toolkits
section when I'm at `agent/key_concepts` docs. I added a short link that
points to the how to section.
While testing out `VectorDBQA` as a `Tool` for one of the conversation,
I happened to get a response from LLM (OpenAI) like this
<code>
Could not parse LLM output: Here's a response using the Product Search
tool:
```json
{
"action": "Product Search",
"action_input": "pots for plants"
}
```
This will allow you to search for pots for your plants and find a
variety of options that are available for purchase. You can use this
information to choose the pots that best fit your needs and preferences.
</code>
i.e. The response had a text before & *after* the expected JSON, leading
to `JSONDecodeError`. It's fixed now, by removing text after '```' to
remove unwanted text.

This will allow you to search for pots for your plants and find a
variety of options that are available for purchase. You can use this
information to choose the pots that best fit your needs and preferences.

This `BSHTMLLoader` document_loader loads an HTML document, extracts
text and adds the page title to the returned Document's metadata. The
loader uses the already installed bs4 package to extract both text
content and the page title.
Included in this PR is an example HTML file and an integration test that
tests against this file.

Tell me a joke.
Completion:
{"setup": "Why don't scientists trust atoms?", "punchline": "Because they make up everything!"}
Parsed completion:
setup="Why don't scientists trust atoms?" punchline='Because they make up everything!'

Hitting some dependency issues relating to this strict pinning. Unsure
of the knock-on effects, but wanted to propose this loosening down a
couple of versions.
PromptLayer now has support for [several different tracking
features.](https://magniv.notion.site/Track-4deee1b1f7a34c1680d085f82567dab9)
In order to use any of these features you need to have a request id
associated with the request.
In this PR we add a boolean argument called `return_pl_id` which will
add `pl_request_id` to the `generation_info` dictionary associated with
a generation.
We also updated the relevant documentation.
The basic vector store example started breaking because `Document`
required `not None` for metadata, but Chroma stores metadata as `None`
if none is provided. This creates a fallback which fixes the basic
tutorial

### Summary
Allows users to pass in `**unstructured_kwargs` to Unstructured document
loaders. Implemented with the `strategy` kwargs in mind, but will pass
in other kwargs like `include_page_breaks` as well. The two currently
supported strategies are `"hi_res"`, which is more accurate but takes
longer, and `"fast"`, which processes faster but with lower accuracy.
The `"hi_res"` strategy is the default. For PDFs, if `detectron2` is not
available and the user selects `"hi_res"`, the loader will fallback to
using the `"fast"` strategy.
### Testing
#### Make sure the `strategy` kwarg works
Run the following in iPython to verify that the `"fast"` strategy is
indeed faster.
```python
from langchain.document_loaders import UnstructuredFileLoader
loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", strategy="fast", mode="elements")
%timeit loader.load()
loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", mode="elements")
%timeit loader.load()
```
On my system I get:
```python
In [3]: from langchain.document_loaders import UnstructuredFileLoader
In [4]: loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", strategy="fast", mode="elements")
In [5]: %timeit loader.load()
247 ms ± 369 µs per loop (mean ± std. dev. of 7 runs, 1 loop each)
In [6]: loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", mode="elements")
In [7]: %timeit loader.load()
2.45 s ± 31 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
```
#### Make sure older versions of `unstructured` still work
Run `pip install unstructured==0.5.3` and then verify the following runs
without error:
```python
from langchain.document_loaders import UnstructuredFileLoader
loader = UnstructuredFileLoader("layout-parser-paper-fast.pdf", mode="elements")
loader.load()
```

## 🤔 What is this?
Large language models (LLMs) are emerging as a transformative technology, enabling
developers to build applications that they previously could not.
But using these LLMs in isolation is often not enough to
create a truly powerful app - the real power comes when you can combine them with other sources of computation or knowledge.

This repository allows users to serve local chains and agents as RESTful, gRPC, or WebSocket APIs, thanks to [Jina](https://docs.jina.ai/). Deploy your chains & agents with ease and enjoy independent scaling, serverless and autoscaling APIs, as well as a Streamlit playground on Jina AI Cloud.
This repository provides an example of how to deploy a LangChain application with [BentoML](https://github.com/bentoml/BentoML). BentoML is a framework that enables the containerization of machine learning applications as standard OCI images. BentoML also allows for the automatic generation of OpenAPI and gRPC endpoints. With BentoML, you can integrate models from all popular ML frameworks and deploy them as microservices running on the most optimal hardware and scaling independently.
These templates serve as examples of how to build, deploy, and share LangChain applications using Databutton. You can create user interfaces with Streamlit, automate tasks by scheduling Python code, and store files and data in the built-in store. Examples include a Chatbot interface with conversational memory, a Personal search engine, and a starter template for LangChain apps. Deploying and sharing is just one click away.

This page covers how to use the Prediction Guard ecosystem within LangChain.
It is broken into two parts: installation and setup, and then references to specific Prediction Guard wrappers.
## Installation and Setup
- Install the Python SDK with `pip install predictionguard`
- Get an Prediction Guard access token (as described [here](https://docs.predictionguard.com/)) and set it as an environment variable (`PREDICTIONGUARD_TOKEN`)
## LLM Wrapper
There exists a Prediction Guard LLM wrapper, which you can access with
```python
fromlangchain.llmsimportPredictionGuard
```
You can provide the name of your Prediction Guard "proxy" as an argument when initializing the LLM:
```python
pgllm=PredictionGuard(name="your-text-gen-proxy")
```
Alternatively, you can use Prediction Guard's default proxy for SOTA LLMs:
```python
pgllm=PredictionGuard(name="default-text-gen")
```
You can also provide your access token directly as an argument:
You can use the PromptLayer request ID to add a prompt, score, or other metadata to your request. [Read more about it here](https://magniv.notion.site/Track-4deee1b1f7a34c1680d085f82567dab9).
This LLM is identical to the [OpenAI LLM](./openai.md), except that
- all your requests will be logged to your PromptLayer account
- you can add `pl_tags` when instantializing to tag your requests on PromptLayer
- you can add `return_pl_id` when instantializing to return a PromptLayer request id to use [while tracking requests](https://magniv.notion.site/Track-4deee1b1f7a34c1680d085f82567dab9).
PromptLayer also provides native wrappers for [`PromptLayerChatOpenAI`](../modules/chat/examples/promptlayer_chat_openai.ipynb)

This page covers how to run models on Replicate within LangChain.
## Installation and Setup
- Create a [Replicate](https://replicate.com) account. Get your API key and set it as an environment variable (`REPLICATE_API_TOKEN`)
- Install the [Replicate python client](https://github.com/replicate/replicate-python) with `pip install replicate`
## Calling a model
Find a model on the [Replicate explore page](https://replicate.com/explore), and then paste in the model name and version in this format: `owner-name/model-name:version`
For example, for this [dolly model](https://replicate.com/replicate/dolly-v2-12b), click on the API tab. The model name/version would be: `"replicate/dolly-v2-12b:ef0e1aefc61f8e096ebe4db6b2bacc297daf2ef6899f0f7e001ec445893500e5"`
Only the `model` param is required, but any other model parameters can also be passed in with the format `input={model_param: value, ...}`
For example, if we were running stable diffusion and wanted to change the image dimensions:
Answer the following yes/no question by reasoning step by step.
Can a dog drive a car?
"""
llm(prompt)
```
We can call any Replicate model (not just LLMs) using this syntax. For example, we can call [Stable Diffusion](https://replicate.com/stability-ai/stable-diffusion):

This page covers how to use [Yeager.ai](https://yeager.ai) to generate LangChain tools and agents.
## What is Yeager.ai?
Yeager.ai is an ecosystem designed to simplify the process of creating AI agents and tools.
It features yAgents, a No-code LangChain Agent Builder, which enables users to build, test, and deploy AI solutions with ease. Leveraging the LangChain framework, yAgents allows seamless integration with various language models and resources, making it suitable for developers, researchers, and AI enthusiasts across diverse applications.
## yAgents
Low code generative agent designed to help you build, prototype, and deploy Langchain tools with ease.
### How to use?
```
pip install yeagerai-agent
yeagerai-agent
```
Go to http://127.0.0.1:7860
This will install the necessary dependencies and set up yAgents on your system. After the first run, yAgents will create a .env file where you can input your OpenAI API key. You can do the same directly from the Gradio interface under the tab "Settings".
`OPENAI_API_KEY=<your_openai_api_key_here>`
We recommend using GPT-4,. However, the tool can also work with GPT-3 if the problem is broken down sufficiently.
### Creating and Executing Tools with yAgents
yAgents makes it easy to create and execute AI-powered tools. Here's a brief overview of the process:
1. Create a tool: To create a tool, provide a natural language prompt to yAgents. The prompt should clearly describe the tool's purpose and functionality. For example:
`create a tool that returns the n-th prime number`
2. Load the tool into the toolkit: To load a tool into yAgents, simply provide a command to yAgents that says so. For example:
`load the tool that you just created it into your toolkit`
3. Execute the tool: To run a tool or agent, simply provide a command to yAgents that includes the name of the tool and any required parameters. For example:
`generate the 50th prime number`
You can see a video of how it works [here](https://www.youtube.com/watch?v=KA5hCM3RaWE).
As you become more familiar with yAgents, you can create more advanced tools and agents to automate your work and enhance your productivity.
For more information, see [yAgents' Github](https://github.com/yeagerai/yeagerai-agent) or our [docs](https://yeagerai.gitbook.io/docs/general/welcome-to-yeager.ai)

## Memory: Add State to Chains and Agents
So far, all the chains and agents we've gone through have been stateless. But often, you may want a chain or agent to have some concept of "memory" so that it may remember information about its previous interactions. The clearest and simple example of this is when designing a chatbot - you want it to remember previous messages so it can use context from that to have a better conversation. This would be a type of "short-term memory". On the more complex side, you could imagine a chain/agent remembering key pieces of information over time - this would be a form of "long-term memory". For more concrete ideas on the latter, see this [awesome paper](https://memprompt.com/).

## Building a Language Model Application: Chat Models
Similarly, you can use chat models instead of LLMs. Chat models are a variation on language models. While chat models use language models under the hood, the interface they expose is a bit different: rather than expose a "text in, text out" API, they expose an interface where "chat messages" are the inputs and outputs.
Chat model APIs are fairly new, so we are still figuring out the correct abstractions.
## Get Message Completions from a Chat Model
You can get chat completions by passing one or more messages to the chat model. The response will be a message. The types of messages currently supported in LangChain are `AIMessage`, `HumanMessage`, `SystemMessage`, and `ChatMessage` -- `ChatMessage` takes in an arbitrary role parameter. Most of the time, you'll just be dealing with `HumanMessage`, `AIMessage`, and `SystemMessage`.
```python
fromlangchain.chat_modelsimportChatOpenAI
fromlangchain.schemaimport(
AIMessage,
HumanMessage,
SystemMessage
)
chat=ChatOpenAI(temperature=0)
```
You can get completions by passing in a single message.
```python
chat([HumanMessage(content="Translate this sentence from English to French. I love programming.")])
You can go one step further and generate completions for multiple sets of messages using `generate`. This returns an `LLMResult` with an additional `message` parameter:
```python
batch_messages=[
[
SystemMessage(content="You are a helpful assistant that translates English to French."),
HumanMessage(content="Translate this sentence from English to French. I love programming.")
],
[
SystemMessage(content="You are a helpful assistant that translates English to French."),
HumanMessage(content="Translate this sentence from English to French. I love artificial intelligence.")
Similar to LLMs, you can make use of templating by using a `MessagePromptTemplate`. You can build a `ChatPromptTemplate` from one or more `MessagePromptTemplate`s. You can use `ChatPromptTemplate`'s `format_prompt` -- this returns a `PromptValue`, which you can convert to a string or `Message` object, depending on whether you want to use the formatted value as input to an llm or chat model.
For convience, there is a `from_template` method exposed on the template. If you were to use this template, this is what it would look like:
```python
fromlangchain.chat_modelsimportChatOpenAI
fromlangchain.prompts.chatimport(
ChatPromptTemplate,
SystemMessagePromptTemplate,
HumanMessagePromptTemplate,
)
chat=ChatOpenAI(temperature=0)
template="You are a helpful assistant that translates {input_language} to {output_language}."
agent.run("Who is Olivia Wilde's boyfriend? What is his current age raised to the 0.23 power?")
```
```pycon
> Entering new AgentExecutor chain...
Thought: I need to use a search engine to find Olivia Wilde's boyfriend and a calculator to raise his age to the 0.23 power.
Action:
{
"action": "Search",
"action_input": "Olivia Wilde boyfriend"
}
Observation: Sudeikis and Wilde's relationship ended in November 2020. Wilde was publicly served with court documents regarding child custody while she was presenting Don't Worry Darling at CinemaCon 2022. In January 2021, Wilde began dating singer Harry Styles after meeting during the filming of Don't Worry Darling.

```
## Memory: Add State to Chains and Agents
You can use Memory with chains and agents initialized with chat models. The main difference between this and Memory for LLMs is that rather than trying to condense all previous messages into a string, we can keep them as their own unique memory object.
SystemMessagePromptTemplate.from_template("The following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know."),
conversation.predict(input="I'm doing well! Just having a conversation with an AI.")
# -> "That sounds like fun! I'm happy to chat with you. Is there anything specific you'd like to talk about?"
conversation.predict(input="Tell me about yourself.")
# -> "Sure! I am an AI language model created by OpenAI. I was trained on a large dataset of text from the internet, which allows me to understand and generate human-like language. I can answer questions, provide information, and even have conversations like this one. Is there anything else you'd like to know about me?"
Large language models (LLMs) are emerging as a transformative technology, enabling
developers to build applications that they previously could not.
But using these LLMs in isolation is often not enough to
create a truly powerful app - the real power comes when you are able to
combine them with other sources of computation or knowledge.
LangChain is a framework for developing applications powered by language models. We believe that the most powerful and differentiated applications will not only call out to a language model via an API, but will also:
This library is aimed at assisting in the development of those types of applications. Common examples of these types of applications include:
-*Be data-aware*: connect a language model to other sources of data
-*Be agentic*: allow a language model to interact with its environment
**❓ Question Answering over specific documents**
The LangChain framework is designed with the above principles in mind.
This is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see `here <https://docs.langchain.com/docs/>`_. For the JavaScript documentation, see `here <https://js.langchain.com/docs/>`_.

-`Personal Assistants <./use_cases/personal_assistants.html>`_: The main LangChain use case. Personal assistants need to take actions, remember interactions, and have knowledge about your data.
-`Question Answering <./use_cases/question_answering.html>`_: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.
-`Chatbots <./use_cases/chatbots.html>`_: Since language models are good at producing text, that makes them ideal for creating chatbots.
-`Data Augmented Generation<./use_cases/combine_docs.html>`_: Data Augmented Generation involves specific types of chains that first interact with an external datasource to fetch data to use in the generation step. Examples of this include summarization of long pieces of text and question/answering over specific data sources.
-`Querying Tabular Data<./use_cases/tabular.html>`_: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.

-`Interacting with APIs <./use_cases/apis.html>`_: Enabling LLMs to interact with APIs is extremely powerful in order to give them more up-to-date information and allow them to take actions.
-`Extraction <./use_cases/extraction.html>`_: Extract structured information from text.
-`Summarization <./use_cases/summarization.html>`_: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.
-`Evaluation <./use_cases/evaluation.html>`_: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.
-`Generate similar examples <./use_cases/generate_examples.html>`_: Generating similar examples to a given input. This is a common use case for many applications, and LangChain provides some prompts/chains for assisting in this.

Some applications will require not just a predetermined chain of calls to LLMs/other tools,
but potentially an unknown chain that depends on the user's input.
In these types of chains, there is a “agent” which has access to a suite of tools.
Depending on the user input, the agent can then decide which, if any, of these tools to call.
The following sections of documentation are provided:
-`Getting Started <./agents/getting_started.html>`_: A notebook to help you get started working with agents as quickly as possible.
-`Key Concepts <./agents/key_concepts.html>`_: A conceptual guide going over the various concepts related to agents.
-`How-To Guides <./agents/how_to_guides.html>`_: A collection of how-to guides. These highlight how to integrate various types of tools, how to work with different types of agents, and how to customize agents.
-`Reference <../reference/modules/agents.html>`_: API reference documentation for all Agent classes.
In this section of documentation, we first start with a Getting Started notebook to cover how to use all things related to agents in an end-to-end manner.

We then split the documentation into the following sections:
**Tools**
An overview of the various tools LangChain supports.
**Agents**
An overview of the different agent types.
**Toolkits**
An overview of toolkits, and examples of the different ones LangChain supports.
**Agent Executor**
An overview of the Agent Executor class and examples of how to use it.
"This notebook covers how to combine agents and vectorstores. The use case for this is that you've ingested your data into a vectorstore and want to interact with it in an agentic manner.\n",
"\n",
"The reccomended method for doing so is to create a VectorDBQAChain and then use that as a tool in the overall agent. Let's take a look at doing this below. You can do this with multiple different vectordbs, and use the agent as a way to route between them. There are two different ways of doing this - you can either let the agent use the vectorstores as normal tools, or you can set `return_direct=True` to really just use the agent as a router."

"You can also set `return_direct=True` if you intend to use the agent as a router and just want to directly return the result of the VectorDBQaChain.\n",
"You can also set `return_direct=True` if you intend to use the agent as a router and just want to directly return the result of the RetrievalQAChain.\n",
"\n",
"Notice that in the above examples the agent did some extra work after querying the VectorDBQAChain. You can avoid that and just return the result directly."
"Notice that in the above examples the agent did some extra work after querying the RetrievalQAChain. You can avoid that and just return the result directly."
"In order to get more visibility into what an agent is doing, we can also return intermediate steps. This comes in the form of an extra key in the return value, which is a list of (action, observation) tuples."
"This notebook walks through how to cap an agent at taking a certain number of steps. This can be useful to ensure that they do not go haywire and take too many steps."
"This notebook walks through how to cap an agent executor after a certain amount of time. This can be useful for safeguarding against long running agent runs."

"This notebook goes over how to serialize agents. For this notebook, it is important to understand the distinction we draw between `agents` and `tools`. An agent is the LLM powered decision maker that decides which actions to take and in which order. Tools are various instruments (functions) an agent has access to, through which an agent can interact with the outside world. When people generally use agents, they primarily talk about using an agent WITH tools. However, when we talk about serialization of agents, we are talking about the agent by itself. We plan to add support for serializing an agent WITH tools sometime in the future.\n",
"\n",
"Let's start by creating an agent with tools as we normally do:"
"Let's now serialize the agent. To be explicit that we are serializing ONLY the agent, we will call the `save_agent` method."

"## 1st example: hierarchical planning agent\n",
"\n",
"In this example, we'll consider an approach called hierarchical planning, common in robotics and appearing in recent works for LLMs X robotics. We'll see it's a viable approach to start working with a massive API spec AND to assist with user queries that require multiple steps against the API.\n",
"\n",
"The idea is simple: to get coherent agent behavior over long sequences behavior & to save on tokens, we'll separate concerns: a \"planner\" will be responsible for what endpoints to call and a \"controller\" will be responsible for how to call them.\n",
"\n",
"In the initial implementation, the planner is an LLM chain that has the name and a short description for each endpoint in context. The controller is an LLM agent that is instantiated with documentation for only the endpoints for a particular plan. There's a lot left to get this working very robustly :)\n",
"We'll work with the Spotify API as one of the examples of a somewhat complex API. There's a bit of auth-related setup to do if you want to replicate this.\n",
"\n",
"- You'll have to set up an application in the Spotify developer console, documented [here](https://developer.spotify.com/documentation/general/guides/authorization/), to get credentials: `CLIENT_ID`, `CLIENT_SECRET`, and `REDIRECT_URI`.\n",
"- To get an access tokens (and keep them fresh), you can implement the oauth flows, or you can use `spotipy`. If you've set your Spotify creedentials as environment variables `SPOTIPY_CLIENT_ID`, `SPOTIPY_CLIENT_SECRET`, and `SPOTIPY_REDIRECT_URI`, you can use the helper functions below:"
