e3ea365725 core: use friendlier names for duplicated nodes in mermaid output (#27747)
Thank you for contributing to LangChain!

- [x] **PR title**: "core: use friendlier names for duplicated nodes in
mermaid output"

- **Description:** When generating the Mermaid visualization of a chain,
if the chain had multiple nodes of the same type, the reid function
would replace their names with the UUID node_id. This made the generated
graph difficult to understand. This change deduplicates the nodes in a
chain by appending an index to their names.
- **Issue:** None
- **Discussion:**

- **Dependencies:** None

- [ ] **Add tests and docs**:  
- Currently this functionality is not covered by unit tests, happy to
add tests if you'd like


- [x] **Lint and test**: Run `make format`, `make lint` and `make test`
from the root of the package(s) you've modified. See contribution
guidelines for more: https://python.langchain.com/docs/contributing/

25a1031871 community: Fix a validation error for MoonshotChat (#27801)
- **Description:** Change `MoonshotCommon.client` type from
`_MoonshotClient` to `Any`.
- **Issue:** Fix the issue #27058
- **Dependencies:** No
- **Twitter handle:** TaoWang2218

In PR #17100, the implementation for Moonshot was added, which defined
two classes:

- `MoonshotChat(MoonshotCommon, ChatOpenAI)` in
`langchain_community.chat_models.moonshot`;
- Here, `validate_environment()` assigns **client** as
`openai.OpenAI().chat.completions`
- Note that **client** here is actually a member variable defined in
`ChatOpenAI`;
- `MoonshotCommon` in `langchain_community.llms.moonshot`;
- And here, `validate_environment()` assigns **_client** as
`_MoonshotClient`;
- Note that this is the underscored **_client**, which is defined within
`MoonshotCommon` itself;

At this time, there was no conflict between the two, one being `client`
and the other `_client`.

However, in PR #25878 which fixed #24390, `_client` in `MoonshotCommon`
was changed to `client`. Since then, a conflict in the definition of
`client` has arisen between `MoonshotCommon` and `MoonshotChat`, which
caused `pydantic` validation error.

To fix this issue, the type of `client` in `MoonshotCommon` should be
changed to `Any`.

- Cassettes now total ~62mb over 474 files.
- `docs/scripts/prepare_notebooks_for_ci.py` lists a number of notebooks

8a5807a6b4 docs: Update Milvus documentation to correctly show how to filter in similarity_search (#27723)
### Description/Issue:

I had problems filtering when setting up a local Milvus db and noticed
that the `filter` option in the `similarity_search` and
`similarity_search_with_score` appeared to do nothing. Instead, the
`expr` option should be used.

The `expr` option is correctly used in the retriever example further
down in the documentation.

The `expr` option seems to be correctly passed on, for example
[here](447c0dd2f0/libs/community/langchain_community/vectorstores/milvus.py (L701))

### Solution:

Update the documentation for the functions mentioned to show intended
behavior.

dc171221b3 community[patch]: Fix vLLM integration to apply lora_request (#27731)
**Description:**
- Add the `lora_request` parameter to the VLLM class to support LoRA
model configurations. This enhancement allows users to specify LoRA
requests directly when using VLLM, enabling more flexible and efficient
model customization.

**Issue:**
- No existing issue for `lora_adapter` in VLLM. This PR addresses the
need for configuring LoRA requests within the VLLM framework.
- Reference : [Using LoRA Adapters in
vLLM](https://docs.vllm.ai/en/stable/models/lora.html#using-lora-adapters)


**Example Code :**
Before this change, the `lora_request` parameter was not applied
correctly:

```python
ADAPTER_PATH = "/path/of/lora_adapter"

llm = VLLM(model="Bllossom/llama-3.2-Korean-Bllossom-3B",
           max_new_tokens=512,
           top_k=2,
           top_p=0.90,
           temperature=0.1,
           vllm_kwargs={
               "gpu_memory_utilization":0.5, 
               "enable_lora":True, 
               "max_model_len":1024,
           }
)

print(llm.invoke(
    ["...prompt_content..."], 
    lora_request=LoRARequest("lora_adapter", 1, ADAPTER_PATH)
    ))
```
**Before Change Output:**
```bash
response was not applied lora_request
```
So, I attempted to apply the lora_adapter to
langchain_community.llms.vllm.VLLM.

**current output:**
```bash
response applied lora_request
```

**Dependencies:**
- None

**Lint and test:**
- All tests and lint checks have passed.

9d2f6701e1 DOCS: Fixed import of langchain instead of langchain_nvidia_ai_endpoints for ChatNVIDIA (#27734)
* **PR title**: "docs: Replaced langchain import with
langchain-nvidia-ai-endpoints in NVIDIA Endpoints Tab"

* **PR message**:
+ **Description:** Replaced the import of `langchain` with
`langchain-nvidia-ai-endpoints` in the NVIDIA Endpoints Tab to resolve
an error caused by the documentation attempting to import the generic
`langchain` module despite the targeted import.
	+ **Issue:** 
+ **Dependencies:** No additional dependencies introduced; simply
updated the existing import to a more specific module.
	+ **Twitter handle:** https://x.com/nawaz0x1

* **Add tests and docs**:
+ **Applicability:** Not applicable in this case, as the change is a fix
to an existing integration rather than the addition of a new one.
+ **Rationale:** No new functionality or integrations are introduced,
only a corrective import change.

* **Lint and test**:
	+ **Status:** Completed
	+ **Outcome:** 
		- `make format`: **Passed**
		- `make lint`: **Passed**
		- `make test`: **Passed**

c1d8c33df6 core: JsonOutputParser UTF characters bug (#27306)
**Description:**
This PR fixes an issue where non-ASCII characters in Pydantic field
descriptions were being escaped to their Unicode representations when
using `JsonOutputParser`. The change allows non-ASCII characters to be
preserved in the output, which is especially important for multilingual
support and when working with non-English languages.

**Issue:** Fixes #27256

**Example Code:**
```python
from pydantic import BaseModel, Field
from langchain_core.output_parsers import JsonOutputParser

class Article(BaseModel):
    title: str = Field(description="科学文章的标题")

output_data_structure = Article
parser = JsonOutputParser(pydantic_object=output_data_structure)
print(parser.get_format_instructions())
```
**Previous Output**:
```... "title": {"description": "\\u79d1\\u5b66\\u6587\\u7ae0\\u7684\\u6807\\u9898", "title": "Title", "type": "string"}} ...```

**Current Output**:
```... "title": {"description": "科学文章的标题", "title": "Title", "type":
"string"}} ...```

**Changes made**:
- Modified `json.dumps()` call in
`langchain_core/output_parsers/json.py` to use `ensure_ascii=False`
- Added a unit test to verify Unicode handling

eec35672a4 core[patch]: Improve type checking for the tool decorator (#27460)
**Description:**

When annotating a function with the @tool decorator, the symbol should
have type BaseTool. The previous type annotations did not convey that to
type checkers. This patch creates 4 overloads for the tool function for
the 4 different use cases.

1. @tool decorator with no arguments
2. @tool decorator with only keyword arguments
3. @tool decorator with a name argument (and possibly keyword arguments)
4. Invoking tool as function with a name and runnable positional
arguments

The main function is updated to match the overloads. The changes are
100% backwards compatible (all existing calls should continue to work,
just with better type annotations).

7bc4e320f1 core[patch]: improve performance of InMemoryVectorStore (#27538)
**Description:** We improve the performance of the InMemoryVectorStore.
**Isue:** Originally, similarity was computed document by document:
```
for doc in self.store.values():
            vector = doc["vector"]
            similarity = float(cosine_similarity([embedding], [vector]).item(0))
```
This is inefficient and does not make use of numpy vectorization.
This PR computes the similarity in one vectorized go:
```
docs = list(self.store.values())
similarity = cosine_similarity([embedding], [doc["vector"] for doc in docs])
```
**Dependencies:** None

.clova namespaces instead of .naver?

I would like to keep it as is, unless it is essential to unify the
package name.
(ClovaX is a branding for the model, and I plan to add other models and
components. They need to be managed as separate classes.)

> also, could you clarify the difference between ClovaEmbeddings and
ClovaXEmbeddings?

There are 3 models that are being serviced by embedding, and all are
supported in the current PR. In addition, all the functionality of CLOVA
Studio that serves actual models, such as distinguishing between test
apps and service apps, is supported. The existing PR does not support
this content because it is hard-coded.

6227396e20 partners/HuggingFacePipeline[stream]: Change to use pipeline instead of pipeline.model.generate in stream() (#26531)
## Description

I encountered an error while using the` gemma-2-2b-it model` with the
`HuggingFacePipeline` class and have implemented a fix to resolve this
issue.

### What is Problem

```python
model_id="google/gemma-2-2b-it"


gemma_2_model = AutoModelForCausalLM.from_pretrained(model_id)
gemma_2_tokenizer = AutoTokenizer.from_pretrained(model_id)

gen = pipeline( 
    task='text-generation',
    model=gemma_2_model,
    tokenizer=gemma_2_tokenizer,
    max_new_tokens=1024,
    device=0 if torch.cuda.is_available() else -1,
    temperature=.5,
    top_p=0.7,
    repetition_penalty=1.1,
    do_sample=True,
    )

llm = HuggingFacePipeline(pipeline=gen)

for chunk in llm.stream("Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World."):
    print(chunk, end="", flush=True)
```

This code outputs the following error message:

```
/usr/local/lib/python3.10/dist-packages/transformers/generation/utils.py:1258: UserWarning: Using the model-agnostic default `max_length` (=20) to control the generation length. We recommend setting `max_new_tokens` to control the maximum length of the generation.

RuntimeError: Expected all tensors to be on the same device, but found at least two devices, cuda:0 and cpu! (when checking argument for argument index in method wrapper_CUDA__index_select)
```

On the other hand, in the case of invoke, the output is normal:

```
llm.invoke("Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World.")
```
```
'Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World. Hello World.\n\nThis is a simple program that prints the phrase "Hello World" to the console. \n\n**Here\'s how it works:**\n\n* **`print("Hello World")`**: This line of code uses the `print()` function, which is a built-in function in most programming languages (like Python). The `print()` function takes whatever you put inside its parentheses and displays it on the screen.\n* **`"Hello World"`**:  The text within the double quotes (`"`) is called a string. It represents the message we want to print.\n\n\nLet me know if you\'d like to explore other programming concepts or see more examples! \n'
```

### Problem Analysis

- Apparently, I put kwargs in while generating pipelines and it applied
to `invoke()`, but it's not applied in the `stream()`.
- When using the stream, `inputs = self.pipeline.tokenizer (prompt,
return_tensors = "pt")` enters cpu.
  - This can crash when the model is in gpu.

### Solution

Just use `self.pipeline` instead of `self.pipeline.model.generate`.

- **Original Code**

```python
stopping_criteria = StoppingCriteriaList([StopOnTokens()])

inputs = self.pipeline.tokenizer(prompt, return_tensors="pt")
streamer = TextIteratorStreamer(
    self.pipeline.tokenizer,
    timeout=60.0,
    skip_prompt=skip_prompt,
    skip_special_tokens=True,
)
generation_kwargs = dict(
    inputs,
    streamer=streamer,
    stopping_criteria=stopping_criteria,
    **pipeline_kwargs,
)
t1 = Thread(target=self.pipeline.model.generate, kwargs=generation_kwargs)
t1.start()
```

- **Updated Code**

```python
stopping_criteria = StoppingCriteriaList([StopOnTokens()])

streamer = TextIteratorStreamer(
    self.pipeline.tokenizer,
    timeout=60.0,
    skip_prompt=skip_prompt,
    skip_special_tokens=True,
)
generation_kwargs = dict(
    text_inputs= prompt,
    streamer=streamer,
    stopping_criteria=stopping_criteria,
    **pipeline_kwargs,
)
t1 = Thread(target=self.pipeline, kwargs=generation_kwargs)
t1.start()
```

By using the `pipeline` directly, the `kwargs` of the pipeline are
applied, and there is no need to consider the `device` of the `tensor`
made with the `tokenizer`.

> According to the change to use `pipeline`, it was modified to put
`text_inputs=prompts` directly into `generation_kwargs`.

I found that when upgrading to Pydantic v2, @root_validator was changed
to @model_validator. When a class declares multiple
@model_validator(model=before), the execution order in V1 and V2 is
opposite. This is the reason for ChatSparkLLM's failure.

The correct execution order is to execute build_extra first.


https://github.com/langchain-ai/langchain/blob/langchain%3D%3D0.2.16/libs/community/langchain_community/chat_models/sparkllm.py#L302

And then execute validate_environment.

# Create a DuckDuckGo search instance
search = DuckDuckGoSearchResults()

# Invoke the search
result = search.invoke("Obama")

6d2a76ac05 langchain_huggingface: Fix multiple GPU usage bug in from_model_id function (#23628)
- [ ]  **Description:**   
   - pass the device_map into model_kwargs 
- removing the unused device_map variable in the hf_pipeline function
call
- [ ] **Issue:** issue #13128 
When using the from_model_id function to load a Hugging Face model for
text generation across multiple GPUs, the model defaults to loading on
the CPU despite multiple GPUs being available using the expected format
``` python
llm = HuggingFacePipeline.from_model_id(
    model_id="model-id",
    task="text-generation",
    device_map="auto",
)
```
Currently, to enable multiple GPU , we have to pass in variable in this
format instead
``` python
llm = HuggingFacePipeline.from_model_id(
    model_id="model-id",
    task="text-generation",
    device=None,
    model_kwargs={
        "device_map": "auto",
    }
)
```
This issue arises due to improper handling of the device and device_map
parameters.

- [ ] **Explanation:**
1. In from_model_id, the model is created using model_kwargs and passed
as the model variable of the pipeline function. So at this moment, to
load the model with multiple GPUs, "device_map" needs to be set to
"auto" within model_kwargs. Otherwise, the model defaults to loading on
the CPU.
2. The device_map variable in from_model_id is not utilized correctly.
In the pipeline function's source code of tnansformer:
- The device_map variable is stored in the model_kwargs dictionary
(lines 867-878 of transformers/src/transformers/pipelines/\__init__.py).
```python
    if device_map is not None:
        ......
        model_kwargs["device_map"] = device_map
```
- The model is constructed with model_kwargs containing the device_map
value ONLY IF it is a string (lines 893-903 of
transformers/src/transformers/pipelines/\__init__.py).
```python
    if isinstance(model, str) or framework is None:
        model_classes = {"tf": targeted_task["tf"], "pt": targeted_task["pt"]}
        framework, model = infer_framework_load_model( ... , **model_kwargs, )
```
- Consequently, since a model object is already passed to the pipeline
function, the device_map variable from from_model_id is never used.

3. The device_map variable in from_model_id not only appears unused but
also causes errors. Without explicitly setting device=None, attempting
to load the model on multiple GPUs may result in the following error:
 ```
Device has 2 GPUs available. Provide device={deviceId} to
`from_model_id` to use available GPUs for execution. deviceId is -1
(default) for CPU and can be a positive integer associated with CUDA
device id.
  Traceback (most recent call last):
    File "foo.py", line 15, in <module>
      llm = HuggingFacePipeline.from_model_id(
File
"foo\site-packages\langchain_huggingface\llms\huggingface_pipeline.py",
line 217, in from_model_id
      pipeline = hf_pipeline(
File "foo\lib\site-packages\transformers\pipelines\__init__.py", line
1108, in pipeline
return pipeline_class(model=model, framework=framework, task=task,
**kwargs)
File "foo\lib\site-packages\transformers\pipelines\text_generation.py",
line 96, in __init__
      super().__init__(*args, **kwargs)
File "foo\lib\site-packages\transformers\pipelines\base.py", line 835,
in __init__
      raise ValueError(
ValueError: The model has been loaded with `accelerate` and therefore
cannot be moved to a specific device. Please discard the `device`
argument when creating your pipeline object.
```
This error occurs because, in from_model_id, the default values in from_model_id for device and device_map are -1 and None, respectively. It would passes the statement (`device_map is not None and device < 0`) and keep the device as -1 so the pipeline function later raises an error when trying to move a GPU-loaded model back to the CPU.

ab205e7389 partners/openai + community: Async Azure AD token provider support for Azure OpenAI (#27488)
This PR introduces a new `azure_ad_async_token_provider` attribute to
the `AzureOpenAI` and `AzureChatOpenAI` classes in `partners/openai` and
`community` packages, given it's currently supported on `openai` package
as
[AsyncAzureADTokenProvider](https://github.com/openai/openai-python/blob/main/src/openai/lib/azure.py#L33)
type.

The reason for creating a new attribute is to avoid breaking changes.
Let's say you have an existing code that uses a `AzureOpenAI` or
`AzureChatOpenAI` instance to perform both sync and async operations.
The `azure_ad_token_provider` will work exactly as it is today, while
`azure_ad_async_token_provider` will override it for async requests.

f636c83321 community: Cassandra Vector Store: modernize implementation (#27253)
**Description:** 

This PR updates `CassandraGraphVectorStore` to be based off
`CassandraVectorStore`, instead of using a custom CQL implementation.
This allows users using a `CassandraVectorStore` to upgrade to a
`GraphVectorStore` without having to change their database schema or
re-embed documents.

This PR also updates the documentation of the `GraphVectorStore` base
class and contains native async implementations for the standard graph
methods: `traversal_search` and `mmr_traversal_search` in
`CassandraVectorStore`.

**Issue:** No issue number.

**Dependencies:** https://github.com/langchain-ai/langchain/pull/27078
(already-merged)

**Lint and test**: 
- Lint and tests all pass, including existing
`CassandraGraphVectorStore` tests.
- Also added numerous additional tests based of the tests in
`langchain-astradb` which cover many more scenarios than the existing
tests for `Cassandra` and `CassandraGraphVectorStore`

** BREAKING CHANGE**

Note that this is a breaking change for existing users of
`CassandraGraphVectorStore`. They will need to wipe their database table
and restart.

However:
- The interfaces have not changed. Just the underlying storage
mechanism.
- Any one using `langchain_community.vectorstores.Cassandra` can instead
use `langchain_community.graph_vectorstores.CassandraGraphVectorStore`
and they will gain Graph capabilities without having to re-embed their
existing documents. This is the primary goal of this PR.

ChatPromptTemplate instead of the hardcoded "f-string".
Also updated docs and typing related to `template_format` to be more
up-to-date and specific.

**Dependencies:** None

**Add tests and docs**: Added unit tests to validate fix. Needed to
update `test_chat` snapshot due to adding new attribute
`template_format` in `ImagePromptTemplate`.

1. Move dependencies for running notebooks into monorepo poetry test
deps;
2. Add script to update cassettes for a single notebook;
3. Add cassettes for some how-to guides.

---

To update cassettes for a single notebook, run
`docs/scripts/update_cassettes.sh`. For example:
```
./docs/scripts/update_cassettes.sh docs/docs/how_to/binding.ipynb
```
Requires:
1. monorepo dev and test dependencies installed;
2. env vars required by notebook are set.

Note: How-to guides are not currently run in [scheduled
job](https://github.com/langchain-ai/langchain/actions/workflows/run_notebooks.yml).
Will add cassettes for more how-to guides in subsequent PRs before
adding them to scheduled job.

31e7664afd community[minor]: add proxy support to RecursiveUrlLoader (#27364)
**Description**
This PR introduces the proxies parameter to the RecursiveUrlLoader
class, allowing the user to specify proxy servers for requests. This
update enables crawling through proxy servers, providing enhanced
flexibility for network configurations.
The key changes include:
  1.Added an optional proxies parameter to the constructor (__init__).
2.Updated the documentation to explain the proxies parameter usage with
an example.
3.Modified the _get_child_links_recursive method to pass the proxies
parameter to the requests.get function.



**Sample Usage**

```python
from bs4 import BeautifulSoup as Soup
from langchain_community.document_loaders.recursive_url_loader import RecursiveUrlLoader

proxies = {
    "http": "http://localhost:1080",
    "https": "http://localhost:1080",
}
url = "https://python.langchain.com/docs/concepts/#langchain-expression-language-lcel"
loader = RecursiveUrlLoader(
    url=url, max_depth=1, extractor=lambda x: Soup(x, "html.parser").text,proxies=proxies
)
docs = loader.load()
```

3f74dfc3d8 community[patch]: Fix vLLM integration to filter SamplingParams (#27367)
**Description:**
- This pull request addresses a bug in Langchain's VLLM integration,
where the use_beam_search parameter was erroneously passed to
SamplingParams. The SamplingParams class in vLLM does not support the
use_beam_search argument, which caused a TypeError.

- This PR introduces logic to filter out unsupported parameters,
ensuring that only valid parameters are passed to SamplingParams. As a
result, the integration now functions as expected without errors.

- The bug was reproduced by running the code sample from Langchain’s
documentation, which triggered the error due to the invalid parameter.
This fix resolves that error by implementing proper parameter filtering.

**VLLM Sampling Params Class:**
https://github.com/vllm-project/vllm/blob/main/vllm/sampling_params.py

**Issue:**
I could not found an Issue that belongs to this. Fixes "TypeError:
Unexpected keyword argument 'use_beam_search'" error when using VLLM
from Langchain.

**Dependencies:**
None.

**Tests and Documentation**:
Tests:
No new functionality was added, but I tested the changes by running
multiple prompts through the VLLM integration with various parameter
configurations. All tests passed successfully without breaking
compatibility.

Docs
No documentation changes were necessary as this is a bug fix.

**Reproducing the Error:**

https://python.langchain.com/docs/integrations/llms/vllm/

The code sample from the original documentation can be used to reproduce
the error I got.

from langchain_community.llms import VLLM
llm = VLLM(
    model="mosaicml/mpt-7b",
    trust_remote_code=True,  # mandatory for hf models
    max_new_tokens=128,
    top_k=10,
    top_p=0.95,
    temperature=0.8,
)
print(llm.invoke("What is the capital of France ?"))

443b37403d community: refactor Arxiv search logic (#27084)
PR message:

Description:
This PR refactors the Arxiv API wrapper by extracting the Arxiv search
logic into a helper function (_fetch_results) to reduce code duplication
and improve maintainability. The helper function is used in methods like
get_summaries_as_docs, run, and lazy_load, streamlining the code and
making it easier to maintain in the future.

Issue:
This is a minor refactor, so no specific issue is being fixed.

Dependencies:
No new dependencies are introduced with this change.

Add tests and docs:
No new integrations were added, so no additional tests or docs are
necessary for this PR.
Lint and test:
I have run make format, make lint, and make test to ensure all checks
pass successfully.

This PR updates the integration with OCI data science model deployment
service.

- Update LLM to support streaming and async calls.
- Added chat model.
- Updated tests and docs.
- Updated `libs/community/scripts/check_pydantic.sh` since the use of
`@pre_init` is removed from existing integration.
- Updated `libs/community/extended_testing_deps.txt` as this integration
requires `langchain_openai`.

d05fdd97dd community: Cassandra Vector Store: extend metadata-related methods (#27078)
**Description:** this PR adds a set of methods to deal with metadata
associated to the vector store entries. These, while essential to the
Graph-related extension of the `Cassandra` vector store, are also useful
in themselves. These are (all come in their sync+async versions):

- `[a]delete_by_metadata_filter`
- `[a]replace_metadata`
- `[a]get_by_document_id`
- `[a]metadata_search`

Additionally, a `[a]similarity_search_with_embedding_id_by_vector`
method is introduced to better serve the store's internal working (esp.
related to reranking logic).

**Issue:** no issue number, but now all Document's returned bear their
`.id` consistently (as a consequence of a slight refactoring in how the
raw entries read from DB are made back into `Document` instances).

**Dependencies:** (no new deps: packaging comes through langchain-core
already; `cassio` is now required to be version 0.1.10+)


**Add tests and docs**
Added integration tests for the relevant newly-introduced methods.
(Docs will be updated in a separate PR).

**Lint and test** Lint and (updated) test all pass.

931ce8d026 core[patch]: Update AsyncCallbackManager to honor run_inline attribute and prevent context loss (#26885)
## Description

This PR fixes the context loss issue in `AsyncCallbackManager`,
specifically in `on_llm_start` and `on_chat_model_start` methods. It
properly honors the `run_inline` attribute of callback handlers,
preventing race conditions and ordering issues.

Key changes:
1. Separate handlers into inline and non-inline groups.
2. Execute inline handlers sequentially for each prompt.
3. Execute non-inline handlers concurrently across all prompts.
4. Preserve context for stateful handlers.
5. Maintain performance benefits for non-inline handlers.

**These changes are implemented in `AsyncCallbackManager` rather than
`ahandle_event` because the issue occurs at the prompt and message_list
levels, not within individual events.**

## Testing

- Test case implemented in #26857 now passes, verifying execution order
for inline handlers.

## Related Issues

- Fixes issue discussed in #23909 

## Dependencies

No new dependencies are required.

---

@eyurtsev: This PR implements the discussed changes to respect
`run_inline` in `AsyncCallbackManager`. Please review and advise on any
needed changes.

Added `**kwargs` parameters to the `index` and `aindex` functions in
`libs/core/langchain_core/indexing/api.py`. This allows users to pass
additional arguments to the `add_documents` and `aadd_documents`
methods, enabling the specification of a custom `vector_field`. For
example, users can now use `vector_field="embedding"` when indexing
documents in `OpenSearchVectorStore`

f70650f67d core[patch]: correct typo doc-string for astream_events method (#27108)
This commit addresses a typographical error in the documentation for the
async astream_events method. The word 'evens' was incorrectly used in
the introductory sentence for the reference table, which could lead to
confusion for users.\n\n### Changes Made:\n- Corrected 'Below is a table
that illustrates some evens that might be emitted by various chains.' to
'Below is a table that illustrates some events that might be emitted by
various chains.'\n\nThis enhancement improves the clarity of the
documentation and ensures accurate terminology is used throughout the
reference material.\n\nIssue Reference: #27107

Updating this behavior to support the old instantiations /

Assuming build_extra_kwargs was not something that itself is being used

2538963945 core[patch]: improve index/aindex api when batch_size<n_docs (#25754)
- **Description:** prevent index function to re-index entire source
document even if nothing has changed.
- **Issue:** #22135

I worked on a solution to this issue that is a compromise between being
cheap and being fast.
In the previous code, when batch_size is greater than the number of docs
from a certain source almost the entire source is deleted (all documents
from that source except for the documents in the first batch)
My solution deletes documents from vector store and record manager only
if at least one document has changed for that source.

Hope this can help!

696114e145 community: add sqlite-vec vectorstore (#25003)
**Description**:

Adds a vector store integration with
[sqlite-vec](https://alexgarcia.xyz/sqlite-vec/), the successor to
sqlite-vss that is a single C file with no external dependencies.

Pretty straightforward, just copy-pasted the sqlite-vss integration and
made a few tweaks and added integration tests. Only question is whether
all documentation should be directed away from sqlite-vss if it is
defacto deprecated (cc @asg017).

the chunk size is assumed to be equal 1 in such a case. This is
suprising.

The PR takes into account `self.chunk_size` passed by the user.

a2023a1e96 huggingface; fix huggingface_endpoint.py (initialize clients only with supported kwargs) (#26378)
## Description

By default, `HuggingFaceEndpoint` instantiates both the
`InferenceClient` and the `AsyncInferenceClient` with the
`"server_kwargs"` passed as input. This is an issue as both clients
might not support exactly the same kwargs. This has been highlighted in
https://github.com/huggingface/huggingface_hub/issues/2522 by
@morgandiverrez with the `trust_env` parameter. In order to make
`langchain` integration future-proof, I do think it's wiser to forward
only the supported parameters to each client. Parameters that are not
supported are simply ignored with a warning to the user. From a
`huggingface_hub` maintenance perspective, this allows us much more
flexibility as we are not constrained to support the exact same kwargs

3fc0ea510e community : [bugfix] Use document ids as keys in AzureSearch vectorstore (#25486)
# Description
[Vector store base
class](4cdaca67dc/libs/core/langchain_core/vectorstores/base.py (L65))
currently expects `ids` to be passed in and that is what it passes along
to the AzureSearch vector store when attempting to `add_texts()`.
However AzureSearch expects `keys` to be passed in. When they are not
present, AzureSearch `add_embeddings()` makes up new uuids. This is a
problem when trying to run indexing. [Indexing code
expects](b297af5482/libs/core/langchain_core/indexing/api.py (L371))
the documents to be uploaded using provided ids. Currently AzureSearch
ignores `ids` passed from `indexing` and makes up new ones. Later when
`indexer` attempts to delete removed file, it uses the `id` it had
stored when uploading the document, however it was uploaded under
different `id`.

4e0a6ebe7d community: Add warning when page_content is empty (#25955)
Page content sometimes is empty when PyMuPDF can not find text on pages.
For example, this can happen when the text of the PDF is not copyable
"by hand". Then an OCR solution is need - which is not integrated here.

This warning should accurately warn the user that some pages are lost
during this process.

a47b332841 core: Put Python version as a project requirement so it is considered by ruff (#26608)
Ruff doesn't know about the python version in
`[tool.poetry.dependencies]`. It can get it from
`project.requires-python`.

Notes:
* poetry seems to have issues getting the python constraints from
`requires-python` and using `python` in per dependency constraints. So I
had to duplicate the info. I will open an issue on poetry.
* `inspect.isclass()` doesn't work correctly with `GenericAlias`
(`list[...]`, `dict[..., ...]`) on Python <3.11 so I added some `not
isinstance(type, GenericAlias)` checks:

Python 3.11
```pycon
>>> import inspect
>>> inspect.isclass(list)
True
>>> inspect.isclass(list[str])
False
```

Python 3.9
```pycon
>>> import inspect
>>> inspect.isclass(list)
True
>>> inspect.isclass(list[str])
True
```

- #26370 

`GoogleSpeechToTextLoader` is a deprecated method in
`langchain_community.document_loaders.google_speech_to_text`.

The new recommended usage is to use `SpeechToTextLoader` from
`langchain_google_community`.

When importing from `langchain_google_community`, use the name
`SpeechToTextLoader` instead of the old `GoogleSpeechToTextLoader`.

0a177ec2cc community: Enhance MongoDBLoader with flexible metadata and optimized field extraction (#23376)
### Description:
This pull request significantly enhances the MongodbLoader class in the
LangChain community package by adding robust metadata customization and
improved field extraction capabilities. The updated class now allows
users to specify additional metadata fields through the metadata_names
parameter, enabling the extraction of both top-level and deeply nested
document attributes as metadata. This flexibility is crucial for users
who need to include detailed contextual information without altering the
database schema.

Moreover, the include_db_collection_in_metadata flag offers optional
inclusion of database and collection names in the metadata, allowing for
even greater customization depending on the user's needs.

The loader's field extraction logic has been refined to handle missing
or nested fields more gracefully. It now employs a safe access mechanism
that avoids the KeyError previously encountered when a specified nested
field was absent in a document. This update ensures that the loader can
handle diverse and complex data structures without failure, making it
more resilient and user-friendly.

### Issue:
This pull request addresses a critical issue where the MongodbLoader
class in the LangChain community package could throw a KeyError when
attempting to access nested fields that may not exist in some documents.
The previous implementation did not handle the absence of specified
nested fields gracefully, leading to runtime errors and interruptions in
data processing workflows.

This enhancement ensures robust error handling by safely accessing
nested document fields, using default values for missing data, thus
preventing KeyError and ensuring smoother operation across various data
structures in MongoDB. This improvement is crucial for users working
with diverse and complex data sets, ensuring the loader can adapt to
documents with varying structures without failing.

### Dependencies: 
Requires motor for asynchronous MongoDB interaction.

### Twitter handle: 
N/A

### Add tests and docs
Tests: Unit tests have been added to verify that the metadata inclusion
toggle works as expected and that the field extraction correctly handles
nested fields.
Docs: An example notebook demonstrating the use of the enhanced
MongodbLoader is included in the docs/docs/integrations directory. This
notebook includes setup instructions, example usage, and outputs.
(Here is the notebook link : [colab
link](https://colab.research.google.com/drive/1tp7nyUnzZa3dxEFF4Kc3KS7ACuNF6jzH?usp=sharing))
Lint and test
Before submitting, I ran make format, make lint, and make test as per
the contribution guidelines. All tests pass, and the code style adheres
to the LangChain standards.

```python
import unittest
from unittest.mock import patch, MagicMock
import asyncio
from langchain_community.document_loaders.mongodb import MongodbLoader

class TestMongodbLoader(unittest.TestCase):
    def setUp(self):
        """Setup the MongodbLoader test environment by mocking the motor client 
        and database collection interactions."""
        # Mocking the AsyncIOMotorClient
        self.mock_client = MagicMock()
        self.mock_db = MagicMock()
        self.mock_collection = MagicMock()

        self.mock_client.get_database.return_value = self.mock_db
        self.mock_db.get_collection.return_value = self.mock_collection

        # Initialize the MongodbLoader with test data
        self.loader = MongodbLoader(
            connection_string="mongodb://localhost:27017",
            db_name="testdb",
            collection_name="testcol"
        )

    @patch('langchain_community.document_loaders.mongodb.AsyncIOMotorClient', return_value=MagicMock())
    def test_constructor(self, mock_motor_client):
        """Test if the constructor properly initializes with the correct database and collection names."""
        loader = MongodbLoader(
            connection_string="mongodb://localhost:27017",
            db_name="testdb",
            collection_name="testcol"
        )
        self.assertEqual(loader.db_name, "testdb")
        self.assertEqual(loader.collection_name, "testcol")

    def test_aload(self):
        """Test the aload method to ensure it correctly queries and processes documents."""
        # Setup mock data and responses for the database operations
        self.mock_collection.count_documents.return_value = asyncio.Future()
        self.mock_collection.count_documents.return_value.set_result(1)
        self.mock_collection.find.return_value = [
            {"_id": "1", "content": "Test document content"}
        ]

        # Run the aload method and check responses
        loop = asyncio.get_event_loop()
        results = loop.run_until_complete(self.loader.aload())
        self.assertEqual(len(results), 1)
        self.assertEqual(results[0].page_content, "Test document content")

    def test_construct_projection(self):
        """Verify that the projection dictionary is constructed correctly based on field names."""
        self.loader.field_names = ['content', 'author']
        self.loader.metadata_names = ['timestamp']
        expected_projection = {'content': 1, 'author': 1, 'timestamp': 1}
        projection = self.loader._construct_projection()
        self.assertEqual(projection, expected_projection)

if __name__ == '__main__':
    unittest.main()
```


### Additional Example for Documentation
Sample Data:

```json
[
    {
        "_id": "1",
        "title": "Artificial Intelligence in Medicine",
        "content": "AI is transforming the medical industry by providing personalized medicine solutions.",
        "author": {
            "name": "John Doe",
            "email": "john.doe@example.com"
        },
        "tags": ["AI", "Healthcare", "Innovation"]
    },
    {
        "_id": "2",
        "title": "Data Science in Sports",
        "content": "Data science provides insights into player performance and strategic planning in sports.",
        "author": {
            "name": "Jane Smith",
            "email": "jane.smith@example.com"
        },
        "tags": ["Data Science", "Sports", "Analytics"]
    }
]
```
Example Code:

```python
loader = MongodbLoader(
    connection_string="mongodb://localhost:27017",
    db_name="example_db",
    collection_name="articles",
    filter_criteria={"tags": "AI"},
    field_names=["title", "content"],
    metadata_names=["author.name", "author.email"],
    include_db_collection_in_metadata=True
)

documents = loader.load()

for doc in documents:
    print("Page Content:", doc.page_content)
    print("Metadata:", doc.metadata)
```
Expected Output:

```
Page Content: Artificial Intelligence in Medicine AI is transforming the medical industry by providing personalized medicine solutions.
Metadata: {'author_name': 'John Doe', 'author_email': 'john.doe@example.com', 'database': 'example_db', 'collection': 'articles'}
```

Thank you.

724a53711b docs: Fix missing self argument in _get_docs_with_query method of `Cust… (#26312)
…omSelfQueryRetriever`

This commit corrects an issue in the `_get_docs_with_query` method of
the `CustomSelfQueryRetriever` class. The method was incorrectly using
`self.vectorstore.similarity_search_with_score(query, **search_kwargs)`
without including the `self` argument, which is required for proper
method invocation.

The `self` argument is necessary for calling instance methods and
accessing instance attributes. By including `self` in the method call,
we ensure that the method is correctly executed in the context of the
current instance, allowing it to function as intended.

No other changes were made to the method's logic or functionality.

b3c7ed4913 Adding bind_tools in ChatOctoAI (#26168)
The object extends from
langchain_community.chat_models.openai.ChatOpenAI which doesn't have
`bind_tools` defined. I tried extending from
`langchain_openai.ChatOpenAI` in
https://github.com/langchain-ai/langchain/pull/25975 but that PR got
closed because this is not correct.
So adding our own `bind_tools` (which for now copying from ChatOpenAI is
good enough) will solve the tool calling issue we are having now.

Open source models like Llama3.1 have function calling, but it's not
that great. Therefore, we introduce the option to ignore model's
function calling and just use the prompt-based approach

f49da71e87 community[patch]: change default Neo4j username/password (#25226)
**Description:**

Change the default Neo4j username/password (when not supplied as
environment variable or in code) from `None` to `""`.

Neo4j has an option to [disable
auth](https://neo4j.com/docs/operations-manual/current/configuration/configuration-settings/#config_dbms.security.auth_enabled)
which is helpful when developing. When auth is disabled, the username /
password through the `neo4j` module should be `""` (ie an empty string).

Empty strings get marked as false in
`langchain_core.utils.env.get_from_dict_or_env` -- changing this code /
behaviour would have a wide impact and is undesirable.

In order to both _allow_ access to Neo4j with auth disabled and _not_
impact `langchain_core` this patch is presented. The downside would be
that if a user forgets to set NEO4J_USERNAME or NEO4J_PASSWORD they
would see an invalid credentials error rather than missing credentials
error. This could be mitigated but would result in a less elegant patch!

**Issue:**
Fix issue where langchain cannot communicate with Neo4j if Neo4j auth is
disabled.

fdeaff4149 langchain-mistralai - make base URL possible to set via env variable for ChatMistralAI (#25956)
Thank you for contributing to LangChain!


**Description:** 

Similar to other packages (`langchain_openai`, `langchain_anthropic`) it
would be beneficial if that `ChatMistralAI` model could fetch the API
base URL from the environment.

This PR allows this via the following order:
- provided value
- then whatever `MISTRAL_API_URL` is set to
- then whatever `MISTRAL_BASE_URL` is set to
- if `None`, then default is ` "https://api.mistral.com/v1"`


- [x] **Add tests and docs**:

Added unit tests, docs I feel are unnecessary, as this is just aligning
with other packages that do the same?


- [x] **Lint and test**: 

Additional guidelines:
- Make sure optional dependencies are imported within a function.
- Please do not add dependencies to pyproject.toml files (even optional
ones) unless they are required for unit tests.
- Most PRs should not touch more than one package.
- Changes should be backwards compatible.
- If you are adding something to community, do not re-import it in

66828f4ecc text-splitters[patch]: Modified SpacyTextSplitter to fully keep whitespace when strip_whitespace is false (#23272)
Previously, regardless of whether or not strip_whitespace was set to
true or false, the strip text method in the SpacyTextSplitter class used
`sent.text` to get the sentence. I modified this to include a ternary
such that if strip_whitespace is false, it uses `sent.text_with_ws`
I also modified the project.toml to include the spacy pipeline package
and to lock the numpy version, as higher versions break spacy.

**Description:** 
Adding a new option to the CSVLoader that allows us to implicitly
specify the columns that are used for generating the Document content.
Currently these are implicitly set as "all fields not part of the
metadata_columns".

In some cases however it is useful to have a field both as a metadata
and as part of the document content.

ab527027ac community: Resolve refs recursively when generating openai_fn from OpenAPI spec (#19002)
- **Description:** This PR is intended to improve the generation of
payloads for OpenAI functions when converting from an OpenAPI spec file.
The solution is to recursively resolve `$refs`.
Currently when converting OpenAPI specs into OpenAI functions using
`openapi_spec_to_openai_fn`, if the schemas have nested references, the
generated functions contain `$ref` that causes the LLM to generate
payloads with an incorrect schema.

For example, for the for OpenAPI spec:

              "example": "doggie"
            },
            "category": {
              "ref": "#/components/schemas/Category"
            },
            "tags": {
              "items": {
                "ref": "#/components/schemas/Tag"
              },
              "type": "array"
            },
            "status": {
              "type": "string",
              "enum": [
                "available",
                "pending",
                "sold"
              ],
              "description": "pet status in the store"

            "photoUrls"
          ]
        }
      }
    }
  }
]
```

and the generated JSON has an incorrect schema (e.g. category is filled
with `id` and `name` instead of `model`, `year` and `age`:

```
{
  "id": 1,
  "name": "Scott",
  "category": {
    "id": 1,
    "name": "Dogs"
  },
  "tags": [
    {
      "id": 1,
      "name": "tag1"
    }
  ],
  "status": "available"
}
```

With this change, the generated JSON by the LLM becomes,
`pet_openai_functions` becomes:

```
[
  {
    "name": "addPet",
    "description": "Add a new pet to the store",
    "parameters": {

  }
]
```

and the JSON generated by the LLM is:
```
{
  "id": 1,
  "name": "Scott",
  "category": {
    "year": 2022,
    "model": "Dog",
    "age": 42

  "tags": [
    {
      "id": 1,
      "model_type": 1
    }
  ],
  "status": "available"
}
```

which has the intended schema.

36bbdc776e community: fix bug to support for file_search tool from OpenAI (#25927)
- **Description:** The function `_is_assistants_builtin_tool` didn't had
support for `file_search` from OpenAI. This was creating conflict and
blocking the usage of such. OpenAI Assistant changed from`retrieval` to
`file_search`.
  
  The following code
  
  ```
              agent = OpenAIAssistantV2Runnable.create_assistant(
                name="Data Analysis Assistant",
                instructions=prompt[0].content,
                tools={'type': 'file_search'},
                model=self.chat_config.connection.deployment_name,
                client=llm,
                as_agent=True,
                tool_resources={
                    "file_search": {
                        "vector_store_ids": vector_store_id
                        }
                    }
                )
```

Was throwing the following error

```

With the proposed changes, this is fixed and the function will have support for `file_search`.
  This was the only place missing the support for `file_search`.

7f857a02d5 docs: HuggingFace pipeline returns the prompt if return_full_text is not set (#25916)
Thank you for contributing to LangChain!

**Description:**
The current documentation of using the Huggingface with Langchain needs
to set return_full_text as False otherwise pipeline by default returns
both the prompt and response as output.


Code to reproduce:
```python
from langchain_huggingface import ChatHuggingFace, HuggingFacePipeline
from langchain_core.messages import (
    HumanMessage,
    SystemMessage,
)

llm = HuggingFacePipeline.from_model_id(
    model_id="microsoft/Phi-3.5-mini-instruct",
    task="text-generation",
    pipeline_kwargs=dict(
        max_new_tokens=512,
        do_sample=False,
        repetition_penalty=1.03,
        # return_full_text=False
    ),
    device=0
)

chat_model = ChatHuggingFace(llm=llm)

messages = [
    SystemMessage(content="You're a helpful assistant"),
    HumanMessage(
        content="What happens when an unstoppable force meets an immovable object?"
    ),
]

ai_msg = chat_model.invoke(messages)
print(ai_msg.content)
```
Output:
```
<|system|>
You're a helpful assistant<|end|>
<|user|>
What happens when an unstoppable force meets an immovable object?<|end|>
<|assistant|>
 The scenario of an "unstoppable force" meeting an "immovable object" is a classic paradox that has puzzled philosophers, scientists, and thinkers for centuries. In physics, however, there are no such things as truly unstoppable forces or immovable objects because all physical entities have mass and interact with other masses through fundamental forces (like gravity).

When we consider the laws of motion, particularly Newton's third law which states that for every action, there is an equal and opposite reaction, it becomes clear that if one were to exist, the other would necessarily be negated by the interaction. For example, if you push against a solid wall with great force, the wall exerts an equal and opposite force back on you, preventing your movement.

In theoretical discussions, this paradox often serves as a thought experiment to explore concepts like determinism versus free will, the limits of physical laws, and the nature of reality itself. However, in practical terms, any force applied to an object will result in some form of deformation, transfer of energy, or movement, depending on the properties of both the force and the object.

So while the idea of an unstoppable force and an immovable object remains a fascinating philosophical conundrum, it does not hold up under the scrutiny of physical laws as we understand them.

64b62f6ae4 community[neo4j_vector]: make embedding dimension check optional (#25737)
**Description:**

Starting from Neo4j 5.23 (22 August 2024), with vector-2.0 indexes,
`vector.dimensions` is not required to be set, which will cause it the
key not exist error in index config if it's not set.

Since the existence of vector.dimensions will only ensure additional

- Updates the self-query retriever factory to check for the new Qdrant

- Deprecates `QdrantSparseVectorRetriever`, since the vector store
implementation natively supports it now.

b5d670498f partners/milvus: allow creating a vectorstore with sparse embeddings (#25284)
# Description
Milvus (and `pymilvus`) recently added the option to use [sparse
vectors](https://milvus.io/docs/sparse_vector.md#Sparse-Vector) with
appropriate search methods (e.g., `SPARSE_INVERTED_INDEX`) and
embeddings (e.g., `BM25`, `SPLADE`).

This PR allow creating a vector store using langchain's `Milvus` class,
setting the matching vector field type to `DataType.SPARSE_FLOAT_VECTOR`
and the default index type to `SPARSE_INVERTED_INDEX`.

It is only extending functionality, and backward compatible. 

## Note
I also interested in extending the Milvus class further to support multi
vector search (aka hybrid search). Will be happy to discuss that. See
[here](https://github.com/langchain-ai/langchain/discussions/19955),
[here](https://github.com/langchain-ai/langchain/pull/20375), and
[here](https://github.com/langchain-ai/langchain/discussions/22886)
similar needs.

**Description:** Within AzureOpenAIEmbeddings there is a validation to
cap `chunk_size` at 16. The value of 16 is either an old limitation or
was erroneously chosen. I have checked all of the `preview` and `stable`
releases to ensure that the `embeddings` endpoint can handle 2048
entries
[Azure/azure-rest-api-specs](https://github.com/Azure/azure-rest-api-specs/tree/main/specification/cognitiveservices/data-plane/AzureOpenAI/inference).
I have also found many locations that confirm this limit should be 2048:

a017f49fd3 comminity[patch]: fix #25575 YandexGPTs for _grpc_metadata (#25617)
it fixes two issues:

### YGPTs are broken #25575

```
File ....conda/lib/python3.11/site-packages/langchain_community/embeddings/yandex.py:211, in _make_request(self, texts, **kwargs)
..
--> 211 res = stub.TextEmbedding(request, metadata=self._grpc_metadata)  # type: ignore[attr-defined]

AttributeError: 'YandexGPTEmbeddings' object has no attribute '_grpc_metadata'
```
My gut feeling that #23841 is the cause.

I have to drop leading underscore from `_grpc_metadata` for quickfix,
but I just don't know how to do it _pydantic_ enough.

### minor issue:

if we use `api_key`, which is not the best practice the code fails with 

```
File ~/git/...../python3.11/site-packages/langchain_community/embeddings/yandex.py:119, in YandexGPTEmbeddings.validate_environment(cls, values)
...

AttributeError: 'tuple' object has no attribute 'append'
```

- Added new integration test. But it requires YGPT env available and
active account. I don't know how int tests dis\enabled in CI.
 - added small unit tests with mocks. Should be fine.

850bf89e48 community[patch]: Support passing extra params for executing functions in UCFunctionToolkit (#25652)
Thank you for contributing to LangChain!

- [x] **PR title**: "package: description"
- Where "package" is whichever of langchain, community, core,
experimental, etc. is being modified. Use "docs: ..." for purely docs
changes, "templates: ..." for template changes, "infra: ..." for CI
changes.
  - Example: "community: add foobar LLM"


Support passing extra params when executing UC functions:
The params should be a dictionary with key EXECUTE_FUNCTION_ARG_NAME,
the assumption is that the function itself doesn't use such variable
name (starting and ending with double underscores), and if it does we
raise Exception.
If invalid params passing to the execute_statement, we raise Exception
as well.


- [x] **Add tests and docs**: If you're adding a new integration, please
include
1. a test for the integration, preferably unit tests that do not rely on
network access,
2. an example notebook showing its use. It lives in
`docs/docs/integrations` directory.


- [x] **Lint and test**: Run `make format`, `make lint` and `make test`
from the root of the package(s) you've modified. See contribution
guidelines for more: https://python.langchain.com/docs/contributing/

Additional guidelines:

9decd0b243 langchain[patch]: fix moderation chain init (#25778)
[This
commit](d3ca2cc8c3)
has broken the moderation chain so we've faced a crash when migrating
the LangChain from v0.1 to v0.2.

The issue appears that the class attribute the code refers to doesn't
hold the value processed in the `validate_environment` method. We had
`extras={}` in this attribute, and it was casted to `True` when it
should've been `False`. Adding a simple assignment seems to resolve the
issue, though I'm not sure it's the right way.

- [ ] **PR message**: 
- **Description:** Fixed a syntax error in the ChatAnthropic

the expected format for initializing a ChatAnthropic instance in
LangChain.

783397eacb community: avoid double templating in langchain_prompty (#25777)
## Description

In `langchain_prompty`, messages are templated by Prompty. However, a
call to `ChatPromptTemplate` was initiating a second templating. We now
convert parsed messages to `Message` objects before calling
`ChatPromptTemplate`, signifying clearly that they are already
templated.

We also revert #25739 , which applied to this second templating, which
we now avoid, and did not fix the original issue.

## Issue

Closes #25703

555f97becb community[patch]: fix model initialization bug for deepinfra (#25727)
### Description
adds an init method to ChatDeepInfra to set the model_name attribute
accordings to the argument
### Issue
currently, the model_name specified by the user during initialization of
the ChatDeepInfra class is never set. Therefore, it always chooses the
default model (meta-llama/Llama-2-70b-chat-hf, however probably since
this is deprecated it always uses meta-llama/Llama-3-70b-Instruct). We
stumbled across this issue and fixed it as proposed in this pull
request. Feel free to change the fix according to your coding guidelines
and style, this is just a proposal and we want to draw attention to this
problem.
### Dependencies
no additional dependencies required

Feel free to contact me or @timo282 and @finitearth if you have any
questions.

17dffd9741 AI21: tools calling support in Langchain (#25635)
This pull request introduces support for the AI21 tools calling feature,
available by the Jamba-1.5 models. When Jamba-1.5 detects the necessity
to invoke a provided tool, as indicated by the 'tools' parameter passed
to the model:

```
class ToolDefinition(TypedDict, total=False):
    type: Required[Literal["function"]]
    function: Required[FunctionToolDefinition]

class FunctionToolDefinition(TypedDict, total=False):
    name: Required[str]
    description: str
    parameters: ToolParameters

class ToolParameters(TypedDict, total=False):
    type: Literal["object"]
    properties: Required[Dict[str, Any]]
    required: List[str]
```

It will respond with a list of tool calls structured as follows:

```
class ToolCall(AI21BaseModel):
    id: str
    function: ToolFunction
    type: Literal["function"] = "function"

class ToolFunction(AI21BaseModel):
    name: str
    arguments: str
```

This pull request incorporates the necessary modifications to integrate
this functionality into the ai21-langchain library.

### Summary

Add `DatabricksVectorSearch` and `DatabricksEmbeddings` classes to the
`langchain-databricks` partner packages. Core functionality is
unchanged, but the vector search class is largely refactored for
readability and maintainability.

This PR does not add integration tests yet. This will be added once the
Databricks test workspace is ready.

Tagging @efriis as POC


### Tracker
[] Create a package and imgrate ChatDatabricks
[✍️] Migrate DatabricksVectorSearch, DatabricksEmbeddings, and their
docs
~[ ] Migrate UCFunctionToolkit and its doc~
[ ] Add provider document and update README.md
[ ] Add integration tests and set up secrets (after moved to an external
package)
[ ] Add deprecation note to the community implementations.

080741d336 core[patch]: Fix type for inner input in base prompts (#25713)
Thank you for contributing to LangChain!

- [ ] **PR title**: "langchain-core: Fix type"
- The file to modify is located in
/libs/core/langchain_core/prompts/base.py


- [ ] **PR message**: 
- **Description:** The change is a type for the inner input variable,
the type go from dict to Any. This change is required since the method
_validate input expects a type that is not only a dictionary.
    - **Dependencies:** There are no dependencies for this change


- [ ] **Add tests and docs**: 
1. A test is not needed. This error occurs because I overrode a portion
of the _validate_input method, which is causing a 'beartype' to raise an
error.

This PR introduces adjustments to ensure compatibility with the recently
released preview version of [TiDB Serverless Vector
Search](https://tidb.cloud/ai), aiming to prevent user confusion.

- TiDB Vector now supports vector indexing with cosine and l2 distance
strategies, although inner_product remains unsupported.
- Changing the distance strategy is currently not supported, so the test
cased should be adjusted.

644e0d3463 Use extend method for embeddings concatenation in mlflow_gateway (#14358)
## Description
There is a bug in the concatenation of embeddings obtained from MLflow
that does not conform to the type hint requested by the function.
``` python  
def _query(self, texts: List[str]) -> List[List[float]]:
```
It is logical to expect a **List[List[float]]** for a **List[str]**.
However, the append method encapsulates the response in a global List.
To avoid this, the extend method should be used, which will add the
embeddings of all strings at the same list level.

## Testing
I have tried using OpenAI-ADA to obtain the embeddings, and the result
of executing this snippet is as follows:

``` python  
embeds = await MlflowAIGatewayEmbeddings().aembed_documents(texts=["hi", "how are you?"])
print(embeds)
```  

``` python  
[[[-0.03512698, -0.020624293, -0.015343423, ...], [-0.021260535, -0.011461929, -0.00033121882, ...]]]
```
When in reality, the expected result should be:

``` python  
[[-0.03512698, -0.020624293, -0.015343423, ...], [-0.021260535, -0.011461929, -0.00033121882, ...]]
```
The above result complies with the expected type hint:
**List[List[float]]** . As I mentioned, we can achieve that by using the
extend method instead of the append method.

Issue: When using hybrid search with non-Databricks managed embedding we
currently don't pass both the embedding and query_text to the index.
Hybrid search requires both of these. This change fixes this issue for
both `similarity_search` and `similarity_search_by_vector`.

0258cb96fa core[patch]: add additionalProperties recursively to oai function if strict (#25169)
Hello. 
First of all, thank you for maintaining such a great project.

## Description
In https://github.com/langchain-ai/langchain/pull/25123, support for
structured_output is added. However, `"additionalProperties": false`
needs to be included at all levels when a nested object is generated.

error from current code:
https://gist.github.com/fufufukakaka/e9b475300e6934853d119428e390f204
```
BadRequestError: Error code: 400 - {'error': {'message': "Invalid schema for response_format 'JokeWithEvaluation': In context=('properties', 'self_evaluation'), 'additionalProperties' is required to be supplied and to be false", 'type': 'invalid_request_error', 'param': 'response_format', 'code': None}}
```

              "properties": {
                "explanation": {
                  "type": "string"
                },
                "output": {
                  "type": "string"
                }
              },
              "required": ["explanation", "output"],
              "additionalProperties": false
            }
          },
          "final_answer": {
            "type": "string"
          }
        },
        "required": ["steps", "final_answer"],
        "additionalProperties": false
      }
    }
  }
}
```

In the current code, `"additionalProperties": false` is only added at
the last level.
This PR introduces the `_add_additional_properties_key` function, which
recursively adds `"additionalProperties": false` to the entire JSON
schema for the request.

4b63a217c2 "community: Fix GithubFileLoader source code", "docs: Fix GithubFileLoader code sample" (#19943)
This PR adds tiny improvements to the `GithubFileLoader` document loader
and its code sample, addressing the following issues:

1. Currently, the `file_extension` argument of `GithubFileLoader` does
not change its behavior at all.
1. The `GithubFileLoader` sample code in
`docs/docs/integrations/document_loaders/github.ipynb` does not work as
it stands.

The respective solutions I propose are the following:

1. Remove `file_extension` argument from `GithubFileLoader`.
1. Specify the branch as `master` (not the default `main`) and rename
`documents` as `document`.

7d13a2f958 core[patch]: add option to specify the chunk separator in merge_message_runs (#24783)
**Description:**
LLM will stop generating text even in the middle of a sentence if
`finish_reason` is `length` (for OpenAI) or `stop_reason` is
`max_tokens` (for Anthropic).
To obtain longer outputs from LLM, we should call the message generation
API multiple times and merge the results into the text to circumvent the
API's output token limit.
The extra line breaks forced by the `merge_message_runs` function when
seamlessly merging messages can be annoying, so I added the option to
specify the chunk separator.

**Issue:**
No corresponding issues.

**Dependencies:**
No dependencies required.

I was trying to add this package using langchain-cli: `langchain app add
openai-functions-agent-gmail`, but when then try to build the whole
project using poetry or pip, it fails with the following
error:`poetry.core.masonry.utils.module.ModuleOrPackageNotFound: No
file/folder found for package openai-functions-agent-gmail`

This was fixed by modifying the pyproject.toml as in this commit

e499caa9cd community: Give more context on DeepInfra 500 errors (#25671)
Description: DeepInfra 500 errors have useful information in the text
field that isn't being exposed to the user. I updated the error message
to fix this.

As an example, this code

```
from langchain_community.chat_models import ChatDeepInfra
from langchain_core.messages import HumanMessage

model = "meta-llama/Meta-Llama-3-70B-Instruct"
deepinfra_api_token = "..."

model = ChatDeepInfra(model=model, deepinfra_api_token=deepinfra_api_token)

messages = [HumanMessage("All work and no play makes Jack a dull boy\n" * 9000)]
response = model.invoke(messages)
```

Currently gives this error:
```
langchain_community.chat_models.deepinfra.ChatDeepInfraException: DeepInfra Server: Error 500
```

This change would give the following error:
```
langchain_community.chat_models.deepinfra.ChatDeepInfraException: DeepInfra Server error status 500: {"error":{"message":"Requested input length 99009 exceeds maximum input length 8192"}}
```

3981d736df databricks: Add partner package directory and ChatDatabricks implementation (#25430)
### Summary

Create `langchain-databricks` as a new partner packages. This PR does
not migrate all existing Databricks integration, but the package will
eventually contain:

* `ChatDatabricks` (implemented in this PR)
* `DatabricksVectorSearch`
* `DatabricksEmbeddings`
* ~`UCFunctionToolkit`~ (will be done after UC SDK work which
drastically simplify implementation)

Also, this PR does not add integration tests yet. This will be added
once the Databricks test workspace is ready.

Tagging @efriis as POC


### Tracker
[✍️] Create a package and imgrate ChatDatabricks
[ ] Migrate DatabricksVectorSearch, DatabricksEmbeddings, and their docs
~[ ] Migrate UCFunctionToolkit and its doc~
[ ] Add provider document and update README.md
[ ] Add integration tests and set up secrets (after moved to an external
package)
[ ] Add deprecation note to the community implementations.

8e3e532e7d docs: ollama doc update (toolcalling, install, notebook examples) (#25549)
The new `langchain-ollama` package seems pretty well implemented, but I
noticed the docs were still outdated so I decided to fix em up a bit.

- Llama3.1 was release on 23rd of July;
https://ai.meta.com/blog/meta-llama-3-1/
- Ollama supports tool calling since 25th of July;
https://ollama.com/blog/tool-support
- LangChain Ollama partner package was released 1st of august;
https://pypi.org/project/langchain-ollama/

**Problem**: Docs note langchain-community instead of langchain-ollama

**Solution**: Update docs to
https://python.langchain.com/v0.2/docs/integrations/chat/ollama/


**Problem**: OllamaFunctions is deprecated, as noted on
[Integrations](https://python.langchain.com/v0.2/docs/integrations/chat/ollama_functions/):
This was an experimental wrapper that attempts to bolt-on tool calling
support to models that do not natively support it. The [primary Ollama
integration](https://python.langchain.com/v0.2/docs/integrations/chat/ollama/) now
supports tool calling, and should be used instead.

**Solution**: Delete old notebook from repo, update the existing one
with @tool decorator + pydantic examples to the notebook


**Problem**: Llama3.1 was released while llama3-groq-tool-call fine-tune
Is noted in notebooks.

**Solution**: update docs + notebooks to llama3.1 (which has improved
tool calling support)


**Problem**: Install instructions are incomplete, there is no
information to download a model and/or run the Ollama server

**Solution**: Add simple instructions to start the ollama service and
pull model (for toolcalling)

c5bf114c0f together, standard-tests: specify tool_choice in standard tests (#25548)
Here we allow standard tests to specify a value for `tool_choice` via a
`tool_choice_value` property, which defaults to None.

Chat models [available in
Together](https://docs.together.ai/docs/chat-models) have issues passing
standard tool calling tests:
- llama 3.1 models currently [appear to rely on user-side
parsing](https://docs.together.ai/docs/llama-3-function-calling) in
Together;
- Mixtral-8x7B and Mistral-7B (currently tested) consistently do not
call tools in some tests.

Specifying tool_choice also lets us remove an existing `xfail` and use a
smaller model in Groq tests.

75c3c81b8c [Community]: Fix - Open AI Whisper client.audio.transcriptions returning Text Object which raises error (#25271)
- **Description:** The following
[line](fd546196ef/libs/community/langchain_community/document_loaders/parsers/audio.py (L117))
in `OpenAIWhisperParser` returns a text object for some odd reason
despite the official documentation saying it should return `Transcript`
Instance which should have the text attribute. But for the example given
in the issue and even when I tried running on my own, I was directly
getting the text. The small PR accounts for that.
 - **Issue:** : #25218
 

I was able to replicate the error even without the GenericLoader as
shown below and the issue was with `OpenAIWhisperParser`

```python
parser = OpenAIWhisperParser(api_key="sk-fxxxxxxxxx",
                                            response_format="srt",
                                            temperature=0)

0f7b8adddf fix issue: cannot use document_variable_name to override context in create_stuff_documents_chain (#25531)
…he prompt in the create_stuff_documents_chain

Thank you for contributing to LangChain!

- [ ] **PR title**: "langchain:add document_variable_name in the
function _validate_prompt in create_stuff_documents_chain"
 

- [ ] **PR message**: 
- **Description:** add document_variable_name in the function
_validate_prompt in create_stuff_documents_chain
- **Issue:** according to the description of
create_stuff_documents_chain function, the parameter
document_variable_name can be used to override the "context" in the
prompt, but in the function, _validate_prompt it still use DOCUMENTS_KEY
to check if it is a valid prompt, the value of DOCUMENTS_KEY is always
"context", so even through the user use document_variable_name to
override it, the code still tries to check if "context" is in the
prompt, and finally it reports error. so I use document_variable_name to
replace DOCUMENTS_KEY, the default value of document_variable_name is
"context" which is same as DOCUMENTS_KEY, but it can be override by
users.

66e30efa61 experimental: Fix divide by 0 error (#25439)
Within the semantic chunker, when calling `_threshold_from_clusters`
there is the possibility for a divide by 0 error if the
`number_of_chunks` is equal to the length of `distances`.

Fix simply implements a check if these values match to prevent the error
and enable chunking to continue.

9d08369442 community: fix AzureSearch vectorstore asyncronous methods (#24921)
**Description**
Fix the asyncronous methods to retrieve documents from AzureSearch
VectorStore. The previous changes from [this
commit](ffe6ca986e)
create a similar code for the syncronous methods and the asyncronous
ones but the asyncronous client return an asyncronous iterator
"AsyncSearchItemPaged" as said in the issue #24740.
To solve this issue, the syncronous iterators in asyncronous methods
where changed to asyncronous iterators.

@chrislrobert said in [this
comment](https://github.com/langchain-ai/langchain/issues/24740#issuecomment-2254168302)
that there was a still a flaw due to `with` blocks that close the client
after each call. I removed this `with` blocks in the `async_client`
following the same pattern as the sync `client`.

In order to close up the connections, a __del__ method is included to
gently close up clients once the vectorstore object is destroyed.

**Issue:** #24740 and #24064
**Dependencies:** No new dependencies for this change

**Example notebook:** I created a notebook just to test the changes work
and gives the same results as the syncronous methods for vector and
hybrid search. With these changes, the asyncronous methods in the
retriever work as well.

![image](https://github.com/user-attachments/assets/697e431b-9d7f-4d0d-b205-59d051ac2b67)


**Lint and test**: Passes the tests and the linter

2b15518c5f community: add args_schema to SearxSearchResults tool (#25350)
This adds `args_schema` member to `SearxSearchResults` tool. This member
is already present in the `SearxSearchRun` tool in the same file.

I was having `TypeError: Type is not JSON serializable:
AsyncCallbackManagerForToolRun` being thrown in langserve playground
when I was using `SearxSearchResults` tool as a part of chain there.
This fixes the issue, so the error is not raised anymore.

This is a example langserve app that was giving me the error, but it
works properly after the proposed fix:
```python
#!/usr/bin/env python

from fastapi import FastAPI
from langchain_core.prompts import ChatPromptTemplate
from langchain_core.output_parsers import StrOutputParser
from langchain_core.runnables import RunnablePassthrough
from langchain_openai import ChatOpenAI
from langchain_community.utilities import SearxSearchWrapper
from langchain_community.tools.searx_search.tool import SearxSearchResults
from langserve import add_routes

template = """Answer the question based only on the following context:
{context}

Question: {question}
"""
prompt = ChatPromptTemplate.from_template(template)
model = ChatOpenAI()

s = SearxSearchWrapper(searx_host="http://localhost:8080")

search = SearxSearchResults(wrapper=s)

search_chain = (
    {"context": search, "question": RunnablePassthrough()}
    | prompt
    | model
    | StrOutputParser()
)

app = FastAPI()

add_routes(
    app,
    search_chain,
    path="/chain",
)

if __name__ == "__main__":
    import uvicorn

6dd9f053e3 core[patch]: Deprecating beta upsert APIs in vectorstore (#25069)
This PR deprecates the beta upsert APIs in vectorstore.

We'll introduce them in a V2 abstraction instead to keep the existing
vectorstore implementations lighter weight.

The main problem with the existing APIs is that it's a bit more
challenging to
implement the correct behavior w/ respect to IDs since ID can be present
in
both the function signature and as an optional attribute on the document
object.

But VectorStores that pass the standard tests should have implemented
the semantics properly!

# Migrating
## 🚨Breaking Changes for select chains (SQLDatabase) on 7/28/23
Please see the following guides for migratin LangChain code:
In an effort to make `langchain` leaner and safer, we are moving select chains to `langchain_experimental`.
This migration has already started, but we are remaining backwards compatible until 7/28.
On that date, we will remove functionality from `langchain`.
Read more about the motivation and the progress [here](https://github.com/langchain-ai/langchain/discussions/8043).
* Migrate to [LangChain v0.3](https://python.langchain.com/docs/versions/v0_3/)
* Migrate to [LangChain v0.2](https://python.langchain.com/docs/versions/v0_2/)
* Migrating from [LangChain 0.0.x Chains](https://python.langchain.com/docs/versions/migrating_chains/)
* Upgrate to [LangGraph Memory](https://python.langchain.com/docs/versions/migrating_memory/)
### Migrating to `langchain_experimental`
We are moving any experimental components of LangChain, or components with vulnerability issues, into `langchain_experimental`.
This guide covers how to migrate.
### Installation
Previously:
`pip install -U langchain`
Now (only if you want to access things in experimental):
`pip install -U langchain langchain_experimental`
### Things in `langchain.experimental`
Previously:
`from langchain.experimental import ...`
Now:
`from langchain_experimental import ...`
### PALChain
Previously:
`from langchain.chains import PALChain`
Now:
`from langchain_experimental.pal_chain import PALChain`
### SQLDatabaseChain
Previously:
`from langchain.chains import SQLDatabaseChain`
Now:
`from langchain_experimental.sql import SQLDatabaseChain`
Alternatively, if you are just interested in using the query generation part of the SQL chain, you can check out this [`SQL question-answering tutorial`](https://python.langchain.com/v0.2/docs/tutorials/sql_qa/#convert-question-to-sql-query)
`from langchain.chains import create_sql_query_chain`
### `load_prompt` for Python files
Note: this only applies if you want to load Python files as prompts.
If you want to load json/yaml files, no change is needed.
Previously:
`from langchain.prompts import load_prompt`
Now:
`from langchain_experimental.prompts import load_prompt`
The [LangChain CLI](https://python.langchain.com/docs/versions/v0_3/#migrate-using-langchain-cli) can help automatically upgrade your code to use non deprecated imports.
This will be especially helpful if you're still on either version 0.0.x or 0.1.x of LangChain.

## 🚀 How does LangChain help?
The main value props of the LangChain libraries are:
1. **Components**: composable building blocks, tools and integrations for working with language models. Components are modular and easy-to-use, whether you are using the rest of the LangChain framework or not
2. **Off-the-shelf chains**: built-in assemblages of components for accomplishing higher-level tasks
Off-the-shelf chains make it easy to get started. Components make it easy to customize existing chains and build new ones.
Off-the-shelf chains make it easy to get started. Components make it easy to customize existing chains and build new ones.
## LangChain Expression Language (LCEL)
LCEL is the foundation of many of LangChain's components, and is a declarative way to compose chains. LCEL was designed from day 1 to support putting prototypes in production, with no code changes, from the simplest “prompt + LLM” chain to the most complex chains.
LCEL is a key part of LangChain, allowing you to build and organize chains of processes in a straightforward, declarative manner. It was designed to support taking prototypes directly into production without needing to alter any code. This means you can use LCEL to set up everything from basic "prompt + LLM" setups to intricate, multi-step workflows.

Retrieval Augmented Generation involves [loading data](https://python.langchain.com/v0.2/docs/concepts/#document-loaders) from a variety of sources, [preparing it](https://python.langchain.com/v0.2/docs/concepts/#text-splitters), then [searching over (a.k.a. retrieving from)](https://python.langchain.com/v0.2/docs/concepts/#retrievers) it for use in the generation step.

**🤖 Agents**
Agents allow an LLM autonomy over how a task is accomplished. Agents make decisions about which Actions to take, then take that Action, observe the result, and repeat until the task is complete. LangChain provides a [standard interface for agents](https://python.langchain.com/v0.2/docs/concepts/#agents), along with [LangGraph](https://github.com/langchain-ai/langgraph) for building custom agents.
