57ade13b2b fix llm_inputs duplication problem in intermediate_steps in SQLDatabaseChain (#10279)
Use `.copy()` to fix the bug that the first `llm_inputs` element is
overwritten by the second `llm_inputs` element in `intermediate_steps`.

***Problem description:***
In [line 127](

c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L127C17-L127C17)),
the `llm_inputs` of the sql generation step is appended as the first
element of `intermediate_steps`:
```
            intermediate_steps.append(llm_inputs)  # input: sql generation
```

However, `llm_inputs` is a mutable dict, it is updated in [line
179](https://github.com/langchain-ai/langchain/blob/master/libs/experimental/langchain_experimental/sql/base.py#L179)
for the final answer step:
```
                llm_inputs["input"] = input_text
```
Then, the updated `llm_inputs` is appended as another element of
`intermediate_steps` in [line
180](c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L180)):
```
                intermediate_steps.append(llm_inputs)  # input: final answer
```

As a result, the final `intermediate_steps` returned in [line
189](c732d8fffd/libs/experimental/langchain_experimental/sql/base.py (L189C43-L189C43))
actually contains two same `llm_inputs` elements, i.e., the `llm_inputs`
for the sql generation step overwritten by the one for final answer step
by mistake. Users are not able to get the actual `llm_inputs` for the
sql generation step from `intermediate_steps`

Simply calling `.copy()` when appending `llm_inputs` to
`intermediate_steps` can solve this problem.

d78f418c0d Extract abstracts from Pubmed articles, even if they have no extra label (#10245)
### Description
This pull request involves modifications to the extraction method for
abstracts/summaries within the PubMed utility. A condition has been
added to verify the presence of unlabeled abstracts. Now an abstract
will be extracted even if it does not have a subtitle. In addition, the
extraction of the abstract was extended to books.

### Issue
The PubMed utility occasionally returns an empty result when extracting
abstracts from articles, despite the presence of an abstract for the
paper on PubMed. This issue arises due to the varying structure of
articles; some articles follow a "subtitle/label: text" format, while
others do not include subtitles in their abstracts. An example of the
latter case can be found at:
[https://pubmed.ncbi.nlm.nih.gov/37666905/](url)

35297ca0d3 Add feature for extracting images from pdf and recognizing text from images. (#10653)
**Description**

It is for #10423 that it will be a useful feature if we can extract
images from pdf and recognize text on them. I have implemented it with
`PyPDFLoader`, `PyPDFium2Loader`, `PyPDFDirectoryLoader`,
`PyMuPDFLoader`, `PDFMinerLoader`, and `PDFPlumberLoader`.
[RapidOCR](https://github.com/RapidAI/RapidOCR.git) is used to recognize
text on extracted images. It is time-consuming for ocr so a boolen
parameter `extract_images` is set to control whether to extract and
recognize. I have tested the time usage for each parser on my own laptop
thinkbook 14+ with AMD R7-6800H by unit test and the result is:

| extract_images | PyPDFParser | PDFMinerParser | PyMuPDFParser |
PyPDFium2Parser | PDFPlumberParser |
| ------------- | ------------- | ------------- | ------------- |
------------- | ------------- |
| False | 0.27s | 0.39s | 0.06s | 0.08s | 1.01s |
| True  | 17.01s  | 20.67s | 20.32s | 19,75s | 20.55s |

**Issue**

#10423

3b07c0cf3d RL Chain with VowpalWabbit (#10242)
- Description: This PR adds a new chain `rl_chain.PickBest` for learned
prompt variable injection, detailed description and usage can be found
in the example notebook added. It essentially adds a
[VowpalWabbit](https://github.com/VowpalWabbit/vowpal_wabbit) layer
before the llm call in order to learn or personalize prompt variable
selections.

Most of the code is to make the API simple and provide lots of defaults
and data wrangling that is needed to use Vowpal Wabbit, so that the user
of the chain doesn't have to worry about it.

790010703b ArcGISLoader: Limit number of results in query (#10615)
Description: this PR changes the `ArcGISLoader` to set
`return_all_records` to `False` when `result_record_count` is provided
as a keyword argument. Previously, `return_all_records` was `True` by
default and this made the API ignore `result_record_count`.

Issue: `ArcGISLoader` would ignore `result_record_count` unless user
also passed `return_all_records=False`.

2aae1102b0 Instance anonymization (#10501)
### Description

Add instance anonymization - if `John Doe` will appear twice in the
text, it will be treated as the same entity.
The difference between `PresidioAnonymizer` and
`PresidioReversibleAnonymizer` is that only the second one has a
built-in memory, so it will remember anonymization mapping for multiple
texts:

```
>>> anonymizer = PresidioAnonymizer()
>>> anonymizer.anonymize("My name is John Doe. Hi John Doe!")
'My name is Noah Rhodes. Hi Noah Rhodes!'
>>> anonymizer.anonymize("My name is John Doe. Hi John Doe!")
'My name is Brett Russell. Hi Brett Russell!'
```
```
>>> anonymizer = PresidioReversibleAnonymizer()
>>> anonymizer.anonymize("My name is John Doe. Hi John Doe!")
'My name is Noah Rhodes. Hi Noah Rhodes!'
>>> anonymizer.anonymize("My name is John Doe. Hi John Doe!")
'My name is Noah Rhodes. Hi Noah Rhodes!'

4236ae3851 Added Streaming Capability to SageMaker LLMs (#10535)
This PR adds the ability to declare a Streaming response in the
SageMaker LLM by leveraging the `invoke_endpoint_with_response_stream`
capability in `boto3`. It is heavily based on the AWS Blog Post
announcement linked
[here](https://aws.amazon.com/blogs/machine-learning/elevating-the-generative-ai-experience-introducing-streaming-support-in-amazon-sagemaker-hosting/).

It does not add any additional dependencies since it uses the existing

e2d6c41177 Upgrade langchain dependencies. (#11420)
I was hoping this would pick up numpy 1.26, which is required to support
the new Python 3.12 release, but it didn't. It seems that some
transitive dependency requirement on numpy is preventing that, and the
highest we can currently go is 1.24.x.

But to find this out required a 15min `poetry lock`, so I figured we
might as well upgrade the dependencies we can and hopefully make the
next dependency upgrade a bit smaller.

## Description
Currently SQLAlchemy >=1.4.0 is a hard requirement. We are unable to run
`from langchain.vectorstores import FAISS` with SQLAlchemy <1.4.0 due to
top-level imports, even if we aren't even using parts of the library
that use SQLAlchemy. See Testing section for repro. Let's make it so
that langchain is still compatible with SQLAlchemy <1.4.0, especially if
we aren't using parts of langchain that require it.

The main conflict is that SQLAlchemy removed `declarative_base` from
`sqlalchemy.ext.declarative` in 1.4.0 and moved it to `sqlalchemy.orm`.
We can fix this by try-catching the import. This is the same fix as
applied in https://github.com/langchain-ai/langchain/pull/883.

(I see that there seems to be some refactoring going on about isolating
dependencies, e.g.
c87e9fb2ce,
so if this issue will be eventually fixed by isolating imports in
langchain.vectorstores that also works).

## Issue
I can't find a matching issue.

## Dependencies
No additional dependencies

## Maintainer
@hwchase17 since you reviewed
https://github.com/langchain-ai/langchain/pull/883

## Testing
I didn't add a test, but I manually tested this.

1. Current failure:
```
langchain==0.0.305
sqlalchemy==1.3.24
```

``` python
python -i
>>> from langchain.vectorstores import FAISS
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/pay/src/zoolander/vendor3/lib/python3.8/site-packages/langchain/vectorstores/__init__.py", line 58, in <module>
    from langchain.vectorstores.pgembedding import PGEmbedding
  File "/pay/src/zoolander/vendor3/lib/python3.8/site-packages/langchain/vectorstores/pgembedding.py", line 10, in <module>
    from sqlalchemy.orm import Session, declarative_base, relationship
ImportError: cannot import name 'declarative_base' from 'sqlalchemy.orm' (/pay/src/zoolander/vendor3/lib/python3.8/site-packages/sqlalchemy/orm/__init__.py)
```

2. This fix:
```
langchain==<this PR>
sqlalchemy==1.3.24
```

``` python
python -i
>>> from langchain.vectorstores import FAISS
<succeeds>
```

b499de2926 Anthropic system message fix (#11301)
Removes human prompt prefix before system message for anthropic models

Bedrock anthropic api enforces that Human and Assistant messages must be
interleaved (cannot have same type twice in a row). We currently treat
System Messages as human messages when converting messages -> string
prompt. Our validation when using Bedrock/BedrockChat raises an error
when this happens. For ChatAnthropic we don't validate this so no error
is raised, but perhaps the behavior is still suboptimal

34a64101cc Add explanations to GoogleDriveLoader how to avoid errors (#11335)
- **Description:** add a paragraph to the GoogleDriveLoader doc on how
to bypass errors on authentication.

For some reason, specifying credential path via `credentials_path`
constructor parameter when creating `GoogleDriveLoader` makes it so that
the oAuth screen is never showing up when first using GoogleDriveLoader.
Instead, the `RefreshError: ('invalid_grant: Bad Request', {'error':
'invalid_grant', 'error_description': 'Bad Request'})` error happens.
Setting it via `os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = ...`
solves the problem. Also, `token_path` constructor parameter is
mandatory, otherwise another error happens when trying to `load()` for
the first time.

These errors are tricky and time-consuming to figure out, so I believe
it's good to mention them in the docs.

2f83350eac Feat bedrock cohere support (#11230)
**Description:**
Added support for Cohere command model via Bedrock.
With this change it is now possible to use the `cohere.command-text-v14`
model via Bedrock API.

About Streaming: Cohere model outputs 2 additional chunks at the end of
the text being generated via streaming: a chunk containing the text
`<EOS_TOKEN>`, and a chunk indicating the end of the stream. In this
implementation I chose to ignore both chunks. An alternative solution
could be to replace `<EOS_TOKEN>` with `\n`

Tests: manually tested that the new model work with both
`llm.generate()` and `llm.stream()`.
Tested with `temperature`, `p` and `stop` parameters.

**Issue:** #11181 

**Dependencies:** No new dependencies

9e3c1d4463 add HTMLHeaderTextSplitter (#11039)
Description: Similar in concept to the `MarkdownHeaderTextSplitter`, the
`HTMLHeaderTextSplitter` is a "structure-aware" chunker that splits text
at the element level and adds metadata for each header "relevant" to any
given chunk. It can return chunks element by element or combine elements
with the same metadata, with the objectives of (a) keeping related text
grouped (more or less) semantically and (b) preserving context-rich
information encoded in document structures. It can be used with other
text splitters as part of a chunking pipeline.

42d979efdd Improve type hints and interface for SQL execution functionality. (#11353)
The previous API of the `_execute()` function had a few rough edges that
this PR addresses:
- The `fetch` argument was type-hinted as being able to take any string,
but any string other than `"all"` or `"one"` would `raise ValueError`.
The new type hints explicitly declare that only those values are
supported.
- The return type was type-hinted as `Sequence` but using `fetch =
"one"` would actually return a single result item. This was incorrectly
suppressed using `# type: ignore`. We now always return a list.
- Using `fetch = "one"` would return a single item if data was found, or
an empty *list* if no data was found. This was confusing, and we now
always return a list to simplify.
- The return type was `Sequence[Any]` which was a bit difficult to use
since it wasn't clear what one could do with the returned rows. I'm
making the new type `Dict[str, Any]` that corresponds to the column
names and their values in the query.

I've updated the use of this method elsewhere in the file to match the
new behavior.

20b7bd497c Add pending deprecation warning (#11133)
This PR uses 2 dedicated LangChain warnings types for deprecations
(mirroring python's built in deprecation and pending deprecation
warnings).

These deprecation types are unslienced during initialization in
langchain achieving the same default behavior that we have with our
current warnings approach. However, because these warnings have a
dedicated type, users will be able to silence them selectively (I think
this is strictly better than our current handling of warnings).

The PR adds a deprecation warning to llm symbolic math.

require changes.

### Dependencies

Note that an initial mongodb document loader was created 4 months ago,
but the [PR ](https://github.com/langchain-ai/langchain/pull/4285)was
never pulled in. @leo-gan had commented on that PR, but given it is
extremely far behind the master branch and a ton has changed in
Langchain since then (including repo name and structure), I rewrote the
branch and issued a new PR with the expectation that the old one can be
closed.

Please reference that old PR for comments/context, but it can be closed
in favor of this one. Thanks!

1b48d6cb8c LlamaCppEmbeddings: adds verbose parameter, similar to llms.LlamaCpp class (#11038)
## Description

As of now, when instantiating and during inference, `LlamaCppEmbeddings`
outputs (a lot of) verbose when controlled from Langchain binding - it
is a bit annoying when computing the embeddings of long documents, for
instance.

This PR adds `verbose` for `LlamaCppEmbeddings` objects to be able
**not** to print the verbose of the model to `stderr`. It is natively
supported by `llama-cpp-python` and directly passed to the library – the
PR is hence very small.

The value of `verbose` is `True` by default, following the way it is
defined in [`LlamaCpp` (`llamacpp.py`
#L136-L137)](c87e9fb2ce/libs/langchain/langchain/llms/llamacpp.py (L136-L137))

## Issue

_No issue linked_

## Dependencies

_No additional dependency needed_

## To see it in action

```python
from langchain.embeddings import LlamaCppEmbeddings

MODEL_PATH = "<path_to_gguf_file>"

if __name__ == "__main__":
    llm_embeddings = LlamaCppEmbeddings(
        model_path=MODEL_PATH,
        n_gpu_layers=1,
        n_batch=512,
        n_ctx=2048,
        f16_kv=True,
        verbose=False,
    )

a4e0cf6300 SearchApi integration (#11023)
Based on the customers' requests for native langchain integration,
SearchApi is ready to invest in AI and LLM space, especially in
open-source development.

- This is our initial PR and later we want to improve it based on
customers' and langchain users' feedback. Most likely changes will
affect how the final results string is being built.
- We are creating similar native integration in Python and JavaScript.
- The next plan is to integrate into Java, Ruby, Go, and others.
- Feel free to assign @SebastjanPrachovskij as a main reviewer for any
SearchApi-related searches. We will be glad to help and support
langchain development.

a8db594012 fix: short-circuit black and mypy calls when no changes made (#11051)
Both black and mypy expect a list of files or directories as input.
As-is the Makefile computes a list files changed relative to the last
commit; these are passed to black and mypy in the `format_diff` and
`lint_diff` targets. This is done by way of the Makefile variable
`PYTHON_FILES`. This is to save time by skipping running mypy and black
over the whole source tree.

When no changes have been made, this variable is empty, so the call to
black (and mypy) lacks input files. The call exits with error causing
the Makefile target to error out with:

```bash
$ make format_diff
poetry run black
Usage: black [OPTIONS] SRC ...

One of 'SRC' or 'code' is required.
make: *** [format_diff] Error 1
```

This is unexpected and undesirable, as the naive caller (that's me! 😄 )
will think something else is wrong. This commit smooths over this by
short circuiting when `PYTHON_FILES` is empty.

53a9d6115e Xata chat memory FIX (#11145)
- **Description:** Changed data type from `text` to `json` in xata for
improved performance. Also corrected the `additionalKwargs` key in the
`messages()` function to `additional_kwargs` to adhere to `BaseMessage`
requirements.
- **Issue:** The Chathisroty.messages() will return {} of
`additional_kwargs`, as the name is wrong for `additionalKwargs` .

cfa2203c62 Add input/output schemas to runnables (#11063)
This adds `input_schema` and `output_schema` properties to all
runnables, which are Pydantic models for the input and output types
respectively. These are inferred from the structure of the Runnable as
much as possible, the only manual typing needed is
- optionally add type hints to lambdas (which get translated to
input/output schemas)
- optionally add type hint to RunnablePassthrough

These schemas can then be used to create JSON Schema descriptions of
input and output types, see the tests

- [x] Ensure no InputType and OutputType in our classes use abstract
base classes (replace with union of subclasses)
- [x] Implement in BaseChain and LLMChain
- [x] Implement in RunnableBranch
- [x] Implement in RunnableBinding, RunnableMap, RunnablePassthrough,
RunnableEach, RunnableRouter
- [x] Implement in LLM, Prompt, Chat Model, Output Parser, Retriever
- [x] Implement in RunnableLambda from function signature
- [x] Implement in Tool

b05bb9e136 LangServe (#11046)
Adds LangServe package

* Integrate Runnables with Fast API creating Server and a RemoteRunnable
client
* Support multiple runnables for a given server
* Support sync/async/batch/abatch/stream/astream/astream_log on the
client side (using async implementations on server)
* Adds validation using annotations (relying on pydantic under the hood)
-- this still has some rough edges -- e.g., open api docs do NOT
generate correctly at the moment
* Uses pydantic v1 namespace

Known issues: type translation code doesn't handle a lot of types (e.g.,
TypedDicts)

23065f54c0 Added prompt wrapping for Claude with Bedrock (#11090)
- **Description:** Prompt wrapping requirements have been implemented on
the service side of AWS Bedrock for the Anthropic Claude models to
provide parity between Anthropic's offering and Bedrock's offering. This
overnight change broke most existing implementations of Claude, Bedrock
and Langchain. This PR just steals the the Anthropic LLM implementation
to enforce alias/role wrapping and implements it in the existing
mechanism for building the request body. This has also been tested to
fix the chat_model implementation as well. Happy to answer any further
questions or make changes where necessary to get things patched and up
to PyPi ASAP, TY.
- **Issue:** No issue opened at the moment, though will update when
these roll in.
  - **Dependencies:** None

b87cc8b31e add 3 property types in metadata for notiondb loader (#8509)
### Description: 
NotionDB supports a number of common property types. I have found three
common types that are not included in notiondb loader. When programs
loaded them with notiondb, which will cause some metadata information
not to be passed to langchain. Therefore, I added three common types:
- date
- created_time
- last_edit_time.

this is actually an oversight - this merges all dfs into one df. we DO

9306394078 improve the performance of base.py (#8610)
This removes the use of the intermediate df list and directly
concatenates the dataframes if path is a list of strings. The pd.concat
function combines the dataframes efficiently, making it faster and more
memory-efficient compared to appending dataframes to a list.

- Description: this PR adds the support for arxiv identifier of the
ArxivAPIWrapper. I modified the `run()` and `load()` functions in
`arxiv.py`, using regex to recognize if the query is in the form of
arxiv identifier (see
[https://info.arxiv.org/help/find/index.html](https://info.arxiv.org/help/find/index.html)).
If so, it will directly search the paper corresponding to the arxiv
identifier. I also modified and added tests in `test_arxiv.py`.

b7290f01d8 Batching for hf_pipeline (#10795)
The huggingface pipeline in langchain (used for locally hosted models)
does not support batching. If you send in a batch of prompts, it just
processes them serially using the base implementation of _generate:
https://github.com/docugami/langchain/blob/master/libs/langchain/langchain/llms/base.py#L1004C2-L1004C29

This PR adds support for batching in this pipeline, so that GPUs can be
fully saturated. I updated the accompanying notebook to show GPU batch
inference.

4322b246aa docs: add vLLM chat notebook (#10993)
This PR aims at showcasing how to use vLLM's OpenAI-compatible chat API.

### Context
Lanchain already supports vLLM and its OpenAI-compatible `Completion`
API. However, the `ChatCompletion` API was not aligned with OpenAI and
for this reason I've waited for this
[PR](https://github.com/vllm-project/vllm/pull/852) to be merged before
adding this notebook to langchain.

```
This is not correct. We should be able to expect that the vectorsotre
now includes doc1_1, doc1_2, and doc2, but not doc1_1, doc1_2, and
doc1_2.


# Reason
In `index`, the original code is 
```python
uids = []
docs_to_index = []
for doc, hashed_doc, doc_exists in zip(doc_batch, hashed_docs, exists_batch):
    if doc_exists:
        # Must be updated to refresh timestamp.
        record_manager.update([hashed_doc.uid], time_at_least=index_start_dt)
        num_skipped += 1
        continue
    uids.append(hashed_doc.uid)
    docs_to_index.append(doc)
```
In the aforementioned example, `len(doc_batch) == 4`, but
`len(hashed_docs) == len(exists_batch) == 3`. This is because the
deduplication of input documents [doc1_1, doc1_2, doc1_2, doc2] is
[doc1_1, doc1_2, doc2]. So `index` insert doc1_1, doc1_2, doc1_2 with
the uid of doc1_1, doc1_2, doc2.

re-numbering the cells to restore the appearance of a single, smooth

6e02c45ca4 Add integration for Timescale Vector(Postgres) (#10650)
**Description:**
This commit adds a vector store for the Postgres-based vector database
(`TimescaleVector`).

Timescale Vector(https://www.timescale.com/ai) is PostgreSQL++ for AI
applications. It enables you to efficiently store and query billions of
vector embeddings in `PostgreSQL`:
- Enhances `pgvector` with faster and more accurate similarity search on
1B+ vectors via DiskANN inspired indexing algorithm.
- Enables fast time-based vector search via automatic time-based
partitioning and indexing.
- Provides a familiar SQL interface for querying vector embeddings and
relational data.

Timescale Vector scales with you from POC to production:

67c5950df3 Amazon Bedrock Support Streaming (#10393)
### Description

- Add support for streaming with `Bedrock` LLM and `BedrockChat` Chat
Model.
- Bedrock as of now supports streaming for the `anthropic.claude-*` and
`amazon.titan-*` models only, hence support for those have been built.
- Also increased the default `max_token_to_sample` for Bedrock
`anthropic` model provider to `256` from `50` to keep in line with the
`Anthropic` defaults.
- Added examples for streaming responses to the bedrock example
notebooks.

**_NOTE:_**: This PR fixes the issues mentioned in #9897 and makes that
PR redundant.

## 🚀 Quick Start
> **Note:** You can run this repository locally (which is described below) or in a [development container](https://containers.dev/) (which is described in the [.devcontainer folder](https://github.com/hwchase17/langchain/tree/master/.devcontainer)).
This quick start describes running the repository locally.
For a [development container](https://containers.dev/), see the [.devcontainer folder](https://github.com/langchain-ai/langchain/tree/master/.devcontainer).
This project uses [Poetry](https://python-poetry.org/) v1.5.1 as a dependency manager. Check out Poetry's [documentation on how to install it](https://python-poetry.org/docs/#installation) on your system before proceeding.
### Dependency Management: Poetry and other env/dependency managers
❗Note: If you use `Conda` or `Pyenv` as your environment/package manager, avoid dependency conflicts by doing the following first:
1. *Before installing Poetry*, create and activate a new Conda env (e.g. `conda create -n langchain python=3.9`)
2. Install Poetry v1.5.1 (see above)
3. Tell Poetry to use the virtualenv python environment (`poetry config virtualenvs.prefer-active-python true`)
4. Continue with the following steps.
This project uses [Poetry](https://python-poetry.org/) v1.6.1+ as a dependency manager.
❗Note: *Before installing Poetry*, if you use `Conda`, create and activate a new Conda env (e.g. `conda create -n langchain python=3.9`)
Install Poetry: **[documentation on how to install it](https://python-poetry.org/docs/#installation)**.
❗Note: If you use `Conda` or `Pyenv` as your environment/package manager, after installing Poetry,
tell Poetry to use the virtualenv python environment (`poetry config virtualenvs.prefer-active-python true`)
### Core vs. Experimental
There are two separate projects in this repository:
- `langchain`: core langchain code, abstractions, and use cases
- `langchain.experimental`: more experimental code
- `langchain.experimental`: see the [Experimental README](../libs/experimental/README.md) for more information.
Each of these has their OWN development environment.
In order to run any of the commands below, please move into their respective directories.
For example, to contribute to `langchain` run `cd libs/langchain` before getting started with the below.
Each of these has their own development environment. Docs are run from the top-level makefile, but development
is split across separate test & release flows.
To install requirements:
For this quickstart, start with langchain core:
```bash
cd libs/langchain
```
### Local Development Dependencies
Install langchain development requirements (for running langchain, running examples, linting, formatting, tests, and coverage):
```bash
poetry install --with test
```
This will install all requirements for running the package, examples, linting, formatting, tests, and coverage.
Then verify dependency installation:
❗Note: If during installation you receive a `WheelFileValidationError` for `debugpy`, please make sure you are running Poetry v1.5.1. This bug was present in older versions of Poetry (e.g. 1.4.1) and has been resolved in newer releases. If you are still seeing this bug on v1.5.1, you may also try disabling "modern installation" (`poetry config installer.modern-installation false`) and re-installing requirements. See [this `debugpy` issue](https://github.com/microsoft/debugpy/issues/1246) for more details.
```bash
make test
```
Now assuming `make` and `pytest` are installed, you should be able to run the common tasks in the following section. To double check, run `make test` under `libs/langchain`, all tests should pass. If they don't, you may need to pip install additional dependencies, such as `numexpr` and `openapi_schema_pydantic`.
If the tests don't pass, you may need to pip install additional dependencies, such as `numexpr` and `openapi_schema_pydantic`.
## ✅ Common Tasks
If during installation you receive a `WheelFileValidationError` for `debugpy`, please make sure you are running
Poetry v1.6.1+. This bug was present in older versions of Poetry (e.g. 1.4.1) and has been resolved in newer releases.
If you are still seeing this bug on v1.6.1, you may also try disabling "modern installation"
(`poetry config installer.modern-installation false`) and re-installing requirements.
See [this `debugpy` issue](https://github.com/microsoft/debugpy/issues/1246) for more details.
Type `make` for a list of common tasks.
### Testing
### Code Formatting
_some test dependencies are optional; see section about optional dependencies_.
Formatting for this project is done via a combination of [Black](https://black.readthedocs.io/en/stable/) and [isort](https://pycqa.github.io/isort/).
Unit tests cover modular logic that does not require calls to outside APIs.
If you add new logic, please add a unit test.

#### Spellcheck
Spellchecking for this project is done via [codespell](https://github.com/codespell-project/codespell).

#### Integration Tests
Integration tests cover logic that requires making calls to outside APIs (often integration with other services).

## Features (natively supported)
All LLMs implement the Runnable interface, which comes with default implementations of all methods, ie. `ainvoke`, `batch`, `abatch`, `stream`, `astream`. This gives all LLMs basic support for async, streaming and batch, which by default is implemented as below:
- *Async* support defaults to calling the respective sync method in asyncio's default thread pool executor. This lets other async functions in your application make progress while the LLM is being executed, by moving this call to a background thread.
- *Streaming* support defaults to returning an `Iterator` (or `AsyncIterator` in the case of async streaming) of a single value, the final result returned by the underlying LLM provider. This obviously doesn't give you token-by-token streaming, which requires native support from the LLM provider, but ensures your code that expects an iterator of tokens can work for any of our LLM integrations.
- *Batch* support defaults to calling the underlying LLM in parallel for each input by making use of a thread pool executor (in the sync batch case) or `asyncio.gather` (in the async batch case). The concurrency can be controlled with the `max_concurrency` key in `RunnableConfig`.
Each LLM integration can optionally provide native implementations for async, streaming or batch, which, for providers that support it, can be more efficient. The table shows, for each integration, which features have been implemented with native support.

# LangChain Expression Language (LCEL)
LangChain Expression Language or LCEL is a declarative way to easily compose chains together.
Any chain constructed this way will automatically have full sync, async, and streaming support.
There are several benefits to writing chains in this manner (as opposed to writing normal code):
**Async, Batch, and Streaming Support**
Any chain constructed this way will automatically have full sync, async, batch, and streaming support.
This makes it easy to prototype a chain in a Jupyter notebook using the sync interface, and then expose it as an async streaming interface.
**Fallbacks**
The non-determinism of LLMs makes it important to be able to handle errors gracefully.
With LCEL you can easily attach fallbacks to any chain.
**Parallelism**
Since LLM applications involve (sometimes long) API calls, it often becomes important to run things in parallel.
With LCEL syntax, any components that can be run in parallel automatically are.
**Seamless LangSmith Tracing Integration**
As your chains get more and more complex, it becomes increasingly important to understand what exactly is happening at every step.
With LCEL, **all** steps are automatically logged to [LangSmith](https://smith.langchain.com) for maximal observability and debuggability.
#### [Interface](/docs/expression_language/interface)

# Conversational
This walkthrough demonstrates how to use an agent optimized for conversation. Other agents are often optimized for using tools to figure out the best response, which is not ideal in a conversational setting where you may want the agent to be able to chat with the user as well.

# Agent types
## Action agents
# Agent Types
Agents use an LLM to determine which actions to take and in what order.
An action can either be using a tool and observing its output, or returning a response to the user.
Here are the agents available in LangChain.

## [Structured input ReAct](/docs/modules/agents/agent_types/structured_chat.html)
The structured tool chat agent is capable of using multi-input tools.
Older agents are configured to specify an action input as a single string, but this agent can use a tools' argument
schema to create a structured action input. This is useful for more complex tool usage, like precisely
navigating around a browser.

## [OpenAI Functions](/docs/modules/agents/agent_types/openai_functions_agent.html)
Certain OpenAI models (like gpt-3.5-turbo-0613 and gpt-4-0613) have been explicitly fine-tuned to detect when a
function should be called and respond with the inputs that should be passed to the function.
The OpenAI Functions Agent is designed to work with these models.

This agent is designed to be used in conversational settings.
The prompt is designed to make the agent helpful and conversational.
It uses the ReAct framework to decide which tool to use, and uses memory to remember the previous conversation interactions.

where a Google search API was provided as the tool.

Certain OpenAI models (like gpt-3.5-turbo-0613 and gpt-4-0613) have been fine-tuned to detect when a function should be called and respond with the inputs that should be passed to the function.
In an API call, you can describe functions and have the model intelligently choose to output a JSON object containing arguments to call those functions.
The goal of the OpenAI Function APIs is to more reliably return valid and useful function calls than a generic text completion or chat API.
The OpenAI Functions Agent is designed to work with these models.

@@ -7,20 +7,27 @@ The core idea of agents is to use an LLM to choose a sequence of actions to take
In chains, a sequence of actions is hardcoded (in code).
In agents, a language model is used as a reasoning engine to determine which actions to take and in which order.
Some important terminology (and schema) to know:
1. `AgentAction`: This is a dataclass that represents the action an agent should take. It has a `tool` property (which is the name of the tool that should be invoked) and a `tool_input` property (the input to that tool)
2. `AgentFinish`: This is a dataclass that signifies that the agent has finished and should return to the user. It has a `return_values` parameter, which is a dictionary to return. It often only has one key - `output` - that is a string, and so often it is just this key that is returned.
3. `intermediate_steps`: These represent previous agent actions and corresponding outputs that are passed around. These are important to pass to future iteration so the agent knows what work it has already done. This is typed as a `List[Tuple[AgentAction, Any]]`. Note that observation is currently left as type `Any` to be maximally flexible. In practice, this is often a string.
There are several key components here:
## Agent
This is the class responsible for deciding what step to take next.
This is the chain responsible for deciding what step to take next.
This is powered by a language model and a prompt.
This prompt can include things like:
The inputs to this chain are:
1. The personality of the agent (useful for having it respond in a certain way)
2. Background context for the agent (useful for giving it more context on the types of tasks it's being asked to do)
3. Prompting strategies to invoke better reasoning (the most famous/widely used being [ReAct](https://arxiv.org/abs/2210.03629))
1. List of available tools
2. User input
3. Any previously executed steps (`intermediate_steps`)
LangChain provides a few different types of agents to get started.
Even then, you will likely want to customize those agents with parts (1) and (2).
This chain then returns either the next action to take or the final response to send to the user (`AgentAction` or `AgentFinish`).
Different agents have different prompting styles for reasoning, different ways of encoding input, and different ways of parsing the output.

# Chat models
import DocCardList from "@theme/DocCardList";
## Features (natively supported)
All ChatModels implement the Runnable interface, which comes with default implementations of all methods, ie. `ainvoke`, `batch`, `abatch`, `stream`, `astream`. This gives all ChatModels basic support for async, streaming and batch, which by default is implemented as below:
- *Async* support defaults to calling the respective sync method in asyncio's default thread pool executor. This lets other async functions in your application make progress while the ChatModel is being executed, by moving this call to a background thread.
- *Streaming* support defaults to returning an `Iterator` (or `AsyncIterator` in the case of async streaming) of a single value, the final result returned by the underlying ChatModel provider. This obviously doesn't give you token-by-token streaming, which requires native support from the ChatModel provider, but ensures your code that expects an iterator of tokens can work for any of our ChatModel integrations.
- *Batch* support defaults to calling the underlying ChatModel in parallel for each input by making use of a thread pool executor (in the sync batch case) or `asyncio.gather` (in the async batch case). The concurrency can be controlled with the `max_concurrency` key in `RunnableConfig`.
Each ChatModel integration can optionally provide native implementations to truly enable async or streaming.
The table shows, for each integration, which features have been implemented with native support.
