community[minor]: Azure DocumentIntelligenceLoader/Parser support update with latest SDK (#14389)
- **Description:**
Add DocumentIntelligenceLoader & DocumentIntelligenceParser
implementation using the latest Azure Document Intelligence SDK with
markdown support.
The core logic resides in DocumentIntelligenceParser and
DocumentIntelligenceLoader is a mere wrapper of the parser.
The parser will takes api_endpoint and api_key and creates
DocumentIntelligenceClient for the user. 4 parsing modes are supported:
1. Markdown (default)
2. Single
3. Page 
4. Object

UT and notebook are also updated accordingly.

- **Dependencies:** Azure Document Intelligence SDK:

community[patch]: changed default for VertexAIEmbeddings (#14614)
Replace this entire comment with:
- **Description:** @kurtisvg has raised a point that it's a good idea to
have a fixed version for embeddings (since otherwise a user might run a
query with one version vs a vectorstore where another version was used).
In order to avoid breaking changes, I'd suggest to give users a warning,
and make a `model_name` a required argument in 1.5 months.

This PR updates the code to work with the updated client. The change is
backwards compatible with previous versions of surrealdb client.

core(minor): Implement stream and astream for RunnableBranch (#14805)
* This PR adds `stream` implementations to Runnable Branch.
* Runnable Branch still does not support `transform` so it'll break streaming if it happens in middle or end of sequence, but will work if happens at beginning of sequence.
* Fixes use the async callback manager for async methods
* Handle BaseException rather than Exception, so more errors could be logged as errors when they are encountered

community[patch]: Add param "task" to Databricks LLM to work around serialization of transform_output_fn (#14933)
**What is the reproduce code?**

```python
from langchain.chains import LLMChain, load_chain
from langchain.llms import Databricks
from langchain.prompts import PromptTemplate

def transform_output(response):
    # Extract the answer from the responses.
    return str(response["candidates"][0]["text"])

def transform_input(**request):
    full_prompt = f"""{request["prompt"]}
    Be Concise.
    """
    request["prompt"] = full_prompt
    return request

chat_model = Databricks(
    endpoint_name="llama2-13B-chat-Brambles",
    transform_input_fn=transform_input,
    transform_output_fn=transform_output,
    verbose=True,
)
print(f"Test chat model: {chat_model('What is Apache Spark')}") # This works

llm_chain = LLMChain(llm=chat_model, prompt=PromptTemplate.from_template("{chat_input}"))
llm_chain("colorful socks") # this works
llm_chain.save("databricks_llm_chain.yaml") # transform_input_fn and transform_output_fn are not serialized into the model yaml file
loaded_chain = load_chain("databricks_llm_chain.yaml") # The Databricks LLM is recreated with transform_input_fn=None, transform_output_fn=None.
loaded_chain("colorful socks") # Thus this errors. The transform_output_fn is needed to produce the correct output
```


Error:
```
 File "/local_disk0/.ephemeral_nfs/envs/pythonEnv-6c34afab-3473-421d-877f-1ef18930ef4d/lib/python3.10/site-packages/pydantic/v1/main.py", line 341, in __init__
    raise validation_error
pydantic.v1.error_wrappers.ValidationError: 1 validation error for Generation
text
  str type expected (type=type_error.str)
 request payload: {'query': 'What is a databricks notebook?'}'}
```

**What does the error mean?**

When the LLM generates an answer, represented by a Generation data
object. The Generation data object takes a str field called text, e.g.
Generation(text=”blah”). However, the Databricks LLM tried to put a
non-str to text, e.g. Generation(text={“candidates”:[{“text”: “blah”}]})
Thus, pydantic errors.

**Why the output format becomes incorrect after saving and loading the
Databricks LLM?**

Databrick LLM does not support serializing transform_input_fn and
transform_output_fn, so they are not serialized into the model yaml
file. When the Databricks LLM is loaded, it is recreated with
transform_input_fn=None, transform_output_fn=None. Without
transform_output_fn, the output text is not unwrapped, thus errors.

Missing transform_output_fn causes this error.
Missing transform_input_fn causes the additional prompt “Be Concise.” to
be lost after saving and loading.

community[patch]: Add safe lookup to OpenAI response adapter (#14765)
## Description
Similar to https://github.com/langchain-ai/langchain/issues/5861, I've
experienced `KeyError`s resulting from unsafe lookups in the
`convert_dict_to_message` function in [this
file](https://github.com/langchain-ai/langchain/blob/master/libs/community/langchain_community/adapters/openai.py).
While that issue focused on `KeyError 'content'`, I've opened another
issue (#14764) about how the problem still exists in the same function
but with `KeyError 'role'`. The fix for #5861 only added a safe lookup
to the specific line that was giving them trouble.. This PR fixes the
unsafe lookup in the rest of the function but the problem still exists
across the repo.

## Issues
* #14764
* #5861 

## Dependencies
* None

## Checklist
[x] make format
[x] make lint
[ ] make test - Results in `make: *** No rule to make target 'test'.

Improve prompt injection detection (#14842)
- **Description:** This is addition to [my previous
PR](https://github.com/langchain-ai/langchain/pull/13930) with
improvements to flexibility allowing different models and notebook to
use ONNX runtime for faster speed. Since the last PR, [our
model](https://huggingface.co/laiyer/deberta-v3-base-prompt-injection)
got more than 660k downloads, and with the [public
benchmark](https://huggingface.co/spaces/laiyer/prompt-injection-benchmark)
showed much fewer false-positives than the previous one from deepset.
Additionally, on the ONNX runtime, it can be running 3x faster on the
CPU, which might be handy for builders using Langchain.

    - Add a testcase to enforce the behavior.
  - **Issue:**

**Quick illustration of change:**

```
text = "foo bar baz 123"

tokenizer = Tokenizer(
        chunk_overlap=3,
        tokens_per_chunk=7
)

output = split_text_on_tokens(text=text, tokenizer=tokenizer)
```
output before change: `["foo bar", "bar baz", "baz 123", "123"]`
output after change: `["foo bar", "bar baz", "baz 123"]`

community: replace deprecated davinci models (#14860)
This is technically a breaking change because it'll switch out default
models from `text-davinci-003` to `gpt-3.5-turbo-instruct`, but OpenAI
is shutting off those endpoints on 1/4 anyways.

Feels less disruptive to switch out the default instead.

community[minor]: New model parameters and dynamic batching for VertexAIEmbeddings (#13999)
- **Description:** VertexAIEmbeddings performance improvements
  - **Twitter handle:** @vladkol

## Improvements

- Dynamic batch size, starting from 250, lowering down to 5. Batch size
varies across regions.
Some regions support larger batches, and it significantly improves
performance.
When running large batches of texts in `us-central1`, performance gain
can be up to 3.5x.
The dynamic batching also makes sure every batch is below 20K token
limit.
- New model parameter `embeddings_type` that translates to `task_type`
parameter of the API. Newer model versions support [different embeddings
task
types](https://cloud.google.com/vertex-ai/docs/generative-ai/embeddings/get-text-embeddings#api_changes_to_models_released_on_or_after_august_2023).

community[patch]: Implement similarity_score_threshold for MongoDB Vector Store (#14740)
Adds the option for `similarity_score_threshold` when using
`MongoDBAtlasVectorSearch` as a vector store retriever.

Example use:

```
vector_search = MongoDBAtlasVectorSearch.from_documents(...)

qa_retriever = vector_search.as_retriever(
    search_type="similarity_score_threshold",
    search_kwargs={
        "score_threshold": 0.5,
    }
)

qa = RetrievalQA.from_chain_type(
	llm=OpenAI(), 
	chain_type="stuff", 
	retriever=qa_retriever,
)

docs = qa({"query": "..."})
```

I've tested this feature locally, using a MongoDB Atlas Cluster with a
vector search index.

  - **Tag maintainer:** @hinthornw 

Do want to pass around the PR for a bit and ask a few more marketing
questions before merge, but just want to make sure I'm not working in a
vacuum. No major changes to code functionality intended; the PR should
be for documentation and only minor tweaks.

Note: QA model is a bit borked across staging/prod right now. Relevant
teams have been informed and are looking into it, and I'm placeholdered
the response to that of a working version in the notebook.

Fix token_usage None issue in ChatOpenAI with local Chatglm2-6B (#14493)
When using local Chatglm2-6B by changing OPENAI_BASE_URL to localhost,
the token_usage in ChatOpenAI becomes None. This leads to an
AttributeError when trying to access token_usage.items().

This commit adds a check to ensure token_usage is not None before
accessing its items. This change prevents the AttributeError and allows
ChatOpenAI to work seamlessly with a local Chatglm2-6B model, aligning
with the way it operates with the OpenAI API.

fix(embeddings): huggingface hub embeddings and TEI (#14489)
**Description:** This PR fixes `HuggingFaceHubEmbeddings` by making the
API token optional (as in the client beneath). Most models don't require
one. I also updated the notebook for TEI (text-embeddings-inference)
accordingly as requested here #14288. In addition, I fixed a mistake in
the POST call parameters.

feat: Yaml output parser (#14496)
## Description
New YAML output parser as a drop-in replacement for the Pydantic output
parser. Yaml is a much more token-efficient format than JSON, proving to
be **~35% faster and using the same percentage fewer completion
tokens**.

☑️ Formatted
☑️ Linted
☑️ Tested (analogous to the existing`test_pydantic_parser.py`)

The YAML parser excels in situations where a list of objects is
required, where the root object needs no key:
```python
class Products(BaseModel):
   __root__: list[Product]
```

I ran the prompt `Generate 10 healthy, organic products` 10 times on one
chain using the `PydanticOutputParser`, the other one using
the`YamlOutputParser` with `Products` (see below) being the targeted
model to be created.

LLMs used were Fireworks' `lama-v2-34b-code-instruct` and OpenAI
`gpt-3.5-turbo`. All runs succeeded without validation errors.

```python
class Nutrition(BaseModel):
    sugar: int = Field(description="Sugar in grams")
    fat: float = Field(description="% of daily fat intake")

class Product(BaseModel):
    name: str = Field(description="Product name")
    stats: Nutrition

class Products(BaseModel):
    """A list of products"""

    products: list[Product] # Used `__root__` for the yaml chain
```
Stats after 10 runs reach were as follows:
### JSON
ø time: 7.75s
ø tokens: 380.8

### YAML
ø time: 5.12s
ø tokens: 242.2


Looking forward to feedback, tips and contributions!

experimental[patch]: SmartLLMChain Output Key Customization (#14466)
**Description**
The `SmartLLMChain` was was fixed to output key "resolution".
Unfortunately, this prevents the ability to use multiple `SmartLLMChain`
in a `SequentialChain` because of colliding output keys. This change
simply gives the option the customize the output key to allow for
sequential chaining. The default behavior is the same as the current
behavior.

Now, it's possible to do the following:
```
from langchain.chat_models import ChatOpenAI
from langchain.prompts import PromptTemplate
from langchain_experimental.smart_llm import SmartLLMChain
from langchain.chains import SequentialChain

joke_prompt = PromptTemplate(
    input_variables=["content"],
    template="Tell me a joke about {content}.",
)
review_prompt = PromptTemplate(
    input_variables=["scale", "joke"],
    template="Rate the following joke from 1 to {scale}: {joke}"
)

llm = ChatOpenAI(temperature=0.9, model_name="gpt-4-32k")
joke_chain = SmartLLMChain(llm=llm, prompt=joke_prompt, output_key="joke")
review_chain = SmartLLMChain(llm=llm, prompt=review_prompt, output_key="review")

chain = SequentialChain(
    chains=[joke_chain, review_chain],
    input_variables=["content", "scale"],
    output_variables=["review"],
    verbose=True
)
response = chain.run({"content": "chickens", "scale": "10"})
print(response)
```

s3 = {'value': ['a']}

ops0 = list(jsonpatch.JsonPatch.from_diff(None, s1))
ops1 = list(jsonpatch.JsonPatch.from_diff(s1, s2))
ops2 = list(jsonpatch.JsonPatch.from_diff(s2, s3))
ops = ops0 + ops1 + ops2

jsonpatch.apply_patch(None, ops)
{'value': ['a']}

jsonpatch.apply_patch(None, ops)
{'value': ['a', 'a']}

jsonpatch.apply_patch(None, ops)
{'value': ['a', 'a', 'a']}

feat: 1. Add system parameters, 2. Align with the QianfanChatEndpoint for function calling (#14275)
- **Description:** 
1. Add system parameters to the ERNIE LLM API to set the role of the
LLM.
2. Add support for the ERNIE-Bot-turbo-AI model according from the
document https://cloud.baidu.com/doc/WENXINWORKSHOP/s/Alp0kdm0n.
3. For the function call of ErnieBotChat, align with the
QianfanChatEndpoint.

With this PR, the `QianfanChatEndpoint()` can use the `function calling`
ability with `create_ernie_fn_chain()`. The example is as the following:

```
from langchain.prompts import ChatPromptTemplate
import json
from langchain.prompts.chat import (
    ChatPromptTemplate,
)

from langchain.chat_models import QianfanChatEndpoint
from langchain.chains.ernie_functions import (
    create_ernie_fn_chain,
)

def get_current_news(location: str) -> str:
    """Get the current news based on the location.'

    Args:
        location (str): The location to query.
    
    Returs:
        str: Current news based on the location.
    """

    news_info = {
        "location": location,
        "news": [
            "I have a Book.",
            "It's a nice day, today."
        ]
    }

    return json.dumps(news_info)

def get_current_weather(location: str, unit: str="celsius") -> str:
    """Get the current weather in a given location

    Args:
        location (str): location of the weather.
        unit (str): unit of the tempuature.
    
    Returns:
        str: weather in the given location.
    """

    weather_info = {
        "location": location,
        "temperature": "27",
        "unit": unit,
        "forecast": ["sunny", "windy"],
    }
    return json.dumps(weather_info)

template = ChatPromptTemplate.from_messages([
    ("user", "{user_input}"),
])

chat = QianfanChatEndpoint(model="ERNIE-Bot-4")
chain = create_ernie_fn_chain([get_current_weather, get_current_news], chat, template, verbose=True)
res = chain.run("北京今天的新闻是什么?")
print(res)
```

The result of the above code:
```
> Entering new LLMChain chain...
Prompt after formatting:
Human: 北京今天的新闻是什么?
> Finished chain.
{'name': 'get_current_news', 'arguments': {'location': '北京'}}
```

For the `ErnieBotChat`, now can use the `system` parameter to set the
role of the LLM.

```
from langchain.prompts import ChatPromptTemplate
from langchain.chains import LLMChain
from langchain.chat_models import ErnieBotChat

llm = ErnieBotChat(model_name="ERNIE-Bot-turbo-AI", system="你是一个能力很强的机器人,你的名字叫 小叮当。无论问你什么问题,你都可以给出答案。")
prompt = ChatPromptTemplate.from_messages(
    [
        ("human", "{query}"),
    ]
)
chain = LLMChain(llm=llm, prompt=prompt, verbose=True)
res = chain.run(query="你是谁?")
print(res)
```

The result of the above code:

```
> Entering new LLMChain chain...
Prompt after formatting:
Human: 你是谁?
> Finished chain.
我是小叮当,一个智能机器人。我可以为你提供各种服务,包括回答问题、提供信息、进行计算等。如果你需要任何帮助,请随时告诉我,我会尽力为你提供最好的服务。

function agents to check whether the LLM supports OpenAI functions based

they've been integrated with the OpenAI APIs and have this property set,
even if they don't extend `ChatOpenAI`.

Add CometTracer (#13661)
Hi! I'm Alex, Python SDK Team Lead from
[Comet](https://www.comet.com/site/).

This PR contains our new integration between langchain and Comet -
`CometTracer` class which uses new `comet_llm` python package for
submitting data to Comet.

No additional dependencies for the langchain package are required
directly, but if the user wants to use `CometTracer`, `comet-llm>=2.0.0`
should be installed. Otherwise an exception will be raised from
`CometTracer.__init__`.

A test for the feature is included.

There is also an already existing callback (and .ipynb file with
example) which ideally should be deprecated in favor of a new tracer. I
wasn't sure how exactly you'd prefer to do it. For example we could open
a separate PR for that.

I'm open to your ideas :)

Embaas - added backoff retries for network requests (#13679)
Running a large number of requests to Embaas' servers (or any server)
can result in intermittent network failures (both from local and
external network/service issues). This PR implements exponential backoff
retries to help mitigate this issue.

langchain[patch]: Adding new Github functions for reading pull requests (#9027)
The Github utilities are fantastic, so I'm adding support for deeper
interaction with pull requests. Agents should read "regular" comments
and review comments, and the content of PR files (with summarization or
`ctags` abbreviations).

Progress:
- [x] Add functions to read pull requests and the full content of
modified files.
- [x] Function to use Github's built in code / issues search.

Out of scope:
- Smarter summarization of file contents of large pull requests (`tree`
output, or ctags).
- Smarter functions to checkout PRs and edit the files incrementally
before bulk committing all changes.
- Docs example for creating two agents:
- One watches issues: For every new issue, open a PR with your best
attempt at fixing it.
- The other watches PRs: For every new PR && every new comment on a PR,
check the status and try to finish the job.

langchain[patch]: Fix config arg detection for wrapped lambdarunnable (#14230)
**Description:**
When a RunnableLambda only receives a synchronous callback, this
callback is wrapped into an async one since #13408. However, this
wrapping with `(*args, **kwargs)` causes the `accepts_config` check at
[/libs/core/langchain_core/runnables/config.py#L342](ee94ef55ee/libs/core/langchain_core/runnables/config.py (L342))
to fail, as this checks for the presence of a "config" argument in the
method signature.

Adding a `functools.wraps` around it, resolves it.

always be `[str, bytes]` so that they are more interchangeable.

Add openai v2 adapter (#14063)
### Description

Starting from [openai version
1.0.0](17ac677995 (module-level-client)),
the camel case form of `openai.ChatCompletion` is no longer supported
and has been changed to lowercase `openai.chat.completions`. In
addition, the returned object only accepts attribute access instead of
index access:

```python
import openai

# optional; defaults to `os.environ['OPENAI_API_KEY']`
openai.api_key = '...'

# all client options can be configured just like the `OpenAI` instantiation counterpart
openai.base_url = "https://..."
openai.default_headers = {"x-foo": "true"}

completion = openai.chat.completions.create(
    model="gpt-4",
    messages=[
        {
            "role": "user",
            "content": "How do I output all files in a directory using Python?",
        },
    ],
)
print(completion.choices[0].message.content)
```

So I implemented a compatible adapter that supports both attribute
access and index access:

```python
In [1]: from langchain.adapters import openai as lc_openai
   ...: messages = [{"role": "user", "content": "hi"}]

In [2]: result = lc_openai.chat.completions.create(
   ...:     messages=messages, model="gpt-3.5-turbo", temperature=0
   ...: )

In [3]: result.choices[0].message
Out[3]: {'role': 'assistant', 'content': 'Hello! How can I assist you today?'}

In [4]: result["choices"][0]["message"]
Out[4]: {'role': 'assistant', 'content': 'Hello! How can I assist you today?'}

In [5]: result = await lc_openai.chat.completions.acreate(
   ...:     messages=messages, model="gpt-3.5-turbo", temperature=0
   ...: )

In [6]: result.choices[0].message
Out[6]: {'role': 'assistant', 'content': 'Hello! How can I assist you today?'}

In [7]: result["choices"][0]["message"]
Out[7]: {'role': 'assistant', 'content': 'Hello! How can I assist you today?'}

In [8]: for rs in lc_openai.chat.completions.create(
    ...:     messages=messages, model="gpt-3.5-turbo", temperature=0, stream=True
    ...: ):
    ...:     print(rs.choices[0].delta)
    ...:     print(rs["choices"][0]["delta"])
    ...:
{'role': 'assistant', 'content': ''}
{'role': 'assistant', 'content': ''}
{'content': 'Hello'}
{'content': 'Hello'}
{'content': '!'}
{'content': '!'}

In [20]: async for rs in await lc_openai.chat.completions.acreate(
    ...:     messages=messages, model="gpt-3.5-turbo", temperature=0, stream=True
    ...: ):
    ...:     print(rs.choices[0].delta)
    ...:     print(rs["choices"][0]["delta"])
    ...:
{'role': 'assistant', 'content': ''}
{'role': 'assistant', 'content': ''}
{'content': 'Hello'}
{'content': 'Hello'}
{'content': '!'}
{'content': '!'}
...
```

Extend OpenAIEmbeddings class to support non-tiktoken based embeddings (#13884)
<!-- Thank you for contributing to LangChain!

Replace this entire comment with:
- **Description:** This extends `OpenAIEmbeddings` to add support for
non-`tiktoken` based embeddings, specifically for use with the new
`text-generation-webui` API (`--extensions openai`) which does not
support `tiktoken` encodings, but rather strings
  - **Issue:** Not found,
- **Dependencies:** HuggingFace `transformers.AutoTokenizer` is new
dependency for running the model without `tiktoken`
- **Tag maintainer:** @baskaryan based on last commit for
`langchain-core` refactor
  - **Twitter handle:** @xychelsea

Modified the tokenization process to be model-agnostic, allowing for
both OpenAI and non-OpenAI model tokenizations, by setting the new
default `bool` flag `tiktoken_enabled` to `False`. This requeires
HuggingFace’s AutoTokenizer and handling tokenization for models
requiring different preprocessing steps to generate a chunked string
request rather than a list of integers.

Updated the embeddings generation process to accommodate non-OpenAI
models. This includes converting tokenized text into embeddings using
OpenAI’s and Hugging Face’s model architectures.

Update Hologres vector store: use hologres-vector (#13767)
Hi,
I made some code changes on the Hologres vector store to improve the
data insertion performance.
Also, this version of the code uses `hologres-vector` library. This
library is more convenient for us to update, and more efficient in
performance.
The code has passed the format/lint/spell check. I have run the unit
test for Hologres connecting to my own database.
Please check this PR again and tell me if anything needs to change.

fix(vectorstores): incorrect import for mongodb atlas DriverInfo (#14060)
- **Description:** fix `import` issue for `mongodb atlas` vectore store
integration
  - **Issue:** none
  - **Dependencies:** none

while trying to follow official `langchain`'s [mongodb integration
guide](https://python.langchain.com/docs/integrations/vectorstores/mongodb_atlas),
an import error will happen.

It's caused by incorrect import location:
- `from pymongo import DriverInfo` should be `from pymongo.driver_info
import DriverInfo`
- reference: [pymongo's DriverInfo
class](https://pymongo.readthedocs.io/en/stable/api/pymongo/driver_info.html#pymongo.driver_info.DriverInfo)

Thanks!

Removing extra StdOutCallbackHandler overridden methods (#14136)
Unnecessarily overridden methods:

- Give the idea the subclass is doing something special (when it isn't)
- Block CTRL-click to the actual method

Hi,
There is some unintended behavior in Html2TextTransformer.
The current code is **directly modifying the original documents that are
passed as arguments to the function.**
Therefore, not only the return of the function but also the input
variables are being modified simultaneously.
**To resolve this, I added unit test code as well.**

Objects](https://realpython.com/copying-python-objects/)

Thanks! ☺️

langchain[patch]: Support passing parameters to llms.Databricks and llms.Mlflow (#14100)
Before, we need to use `params` to pass extra parameters:

```python
from langchain.llms import Databricks

Databricks(..., params={"temperature": 0.0})
```

Now, we can directly specify extra params:

```python
from langchain.llms import Databricks

Databricks(..., temperature=0.0)
```

Improve file system blob loader and generic loader (#14004)
* Add support for passing a specific file to the file system blob loader
* Allow specifying a class parameter for the parser for the generic
loader

```python

class AudioLoader(GenericLoader):
  @staticmethod
  def get_parser(**kwargs):
     return MyAudioParser(**kwargs):
```

The intent of the GenericLoader is to provide on-ramps from different
sources (e.g., web, s3, file system).

An alternative is to use pipelining syntax or creating a Pipeline

```
FileSystemBlobLoader(...) | MyAudioParser
```

langchain[patch]: use async_embed_with_retry in _aget_len_safe_embeddings (#14110)
**Description**

`embed_with_retry` is for sync operations and not for async operations.
Use `async_embed_with_retry` for appropriate async operations.


I'm using `OpenAIEmbedding(http_client=httpx.AsyncClient())` with only
async operations.
However, I got an error when I use `embedding.aembed_documents` because
`embed_with_retry` uses sync OpenAI client with async http client.

langchain[minor]: Migrate mlflow and databricks classes to deployments APIs. (#13699)
## Description

Related to https://github.com/mlflow/mlflow/pull/10420. MLflow AI
gateway will be deprecated and replaced by the `mlflow.deployments`
module. Happy to split this PR if it's too large.

```
pip install git+https://github.com/langchain-ai/langchain.git@refs/pull/13699/merge#subdirectory=libs/langchain
```

## Dependencies

Install mlflow from https://github.com/mlflow/mlflow/pull/10420:

```
pip install git+https://github.com/mlflow/mlflow.git@refs/pull/10420/merge
```

## Testing plan

The following code works fine on local and databricks:

core[patch]: Add **kwargs to Langchain's dumps() to allow passing of json.dumps() … (#10628)
…parameters.

In Langchain's `dumps()` function, I've added a `**kwargs` parameter.
This allows users to pass additional parameters to the underlying
`json.dumps()` function, providing greater flexibility and control over
JSON serialization.

Many parameters available in `json.dumps()` can be useful or even
necessary in specific situations. For example, when using an Agent with
return_intermediate_steps set to true, the output is a list of
AgentAction objects. These objects can't be serialized without using
Langchain's `dumps()` function.

The issue arises when using the Agent with a language other than
English, which may contain non-ASCII characters like 'é'. The default
behavior of `json.dumps()` sets ensure_ascii to true, converting
`{"name": "José"}` into `{"name": "Jos\u00e9"}`. This can make the
output hard to read, especially in the case of intermediate steps in
agent logs.

By allowing users to pass additional parameters to `json.dumps()` via
Langchain's dumps(), we can solve this problem. For instance, users can
set `ensure_ascii=False` to maintain the original characters.

This update also enables users to pass other useful `json.dumps()`
parameters like `sort_keys`, providing even more flexibility.

The implementation takes into account edge cases where a user might pass
a "default" parameter, which is already defined by `dumps()`, or an
"indent" parameter, which is also predefined if `pretty=True` is set.

### Description
Hello, 

The [integration_test
README](https://github.com/langchain-ai/langchain/tree/master/libs/langchain/tests)
was indicating incorrect paths for the `.env.example` and `.env` files.

`tests/.env.example` ->`tests/integration_tests/.env.example`

While it’s a minor error, it could **potentially lead to confusion** for
the document’s readers, so I’ve made the necessary corrections.

Thank you! ☺️

Added support for a Pandas DataFrame OutputParser (#13257)
**Description:**

Added support for a Pandas DataFrame OutputParser with format
instructions, along with unit tests and a demo notebook. Namely, we've
added the ability to request data from a DataFrame, have the LLM parse
the request, and then use that request to retrieve a well-formatted
response.

Within LangChain, it seamlessly integrates with language models like
OpenAI's `text-davinci-003`, facilitating streamlined interaction using
the format instructions (just like the other output parsers).

This parser structures its requests as
`<operation/column/row>[<optional_array_params>]`. The instructions
detail permissible operations, valid columns, and array formats,
ensuring clarity and adherence to the required format.

For example:

- When the LLM receives the input: "Retrieve the mean of `num_legs` from
rows 1 to 3."
- The provided format instructions guide the LLM to structure the
request as: "mean:num_legs[1..3]".

The parser processes this formatted request, leveraging the LLM's
understanding to extract the mean of `num_legs` from rows 1 to 3 within
the Pandas DataFrame.

This integration allows users to communicate requests naturally, with
the LLM transforming these instructions into structured commands
understood by the `PandasDataFrameOutputParser`. The format instructions
act as a bridge between natural language queries and precise DataFrame
operations, optimizing communication and data retrieval.

**Issue:**

Implemented MongoDB Atlas Self-Query Retriever (#13321)
# Description 
This PR implements Self-Query Retriever for MongoDB Atlas vector store.

I've implemented the comparators and operators that are supported by
MongoDB Atlas vector store according to the section titled "Atlas Vector
Search Pre-Filter" from
https://www.mongodb.com/docs/atlas/atlas-vector-search/vector-search-stage/.

Namely:
```
allowed_comparators = [
      Comparator.EQ,
      Comparator.NE,
      Comparator.GT,
      Comparator.GTE,
      Comparator.LT,
      Comparator.LTE,
      Comparator.IN,
      Comparator.NIN,
  ]

"""Subset of allowed logical operators."""
allowed_operators = [
    Operator.AND,
    Operator.OR
]
```
Translations from comparators/operators to MongoDB Atlas filter
operators(you can find the syntax in the "Atlas Vector Search
Pre-Filter" section from the previous link) are done using the following
dictionary:
```
map_dict = {
            Operator.AND: "$and",
            Operator.OR: "$or",
            Comparator.EQ: "$eq",
            Comparator.NE: "$ne",
            Comparator.GTE: "$gte",
            Comparator.LTE: "$lte",
            Comparator.LT: "$lt",
            Comparator.GT: "$gt",
            Comparator.IN: "$in",
            Comparator.NIN: "$nin",
        }
```

In visit_structured_query() the filters are passed as "pre_filter" and
not "filter" as in the MongoDB link above since langchain's
implementation of MongoDB atlas vector
store(libs\langchain\langchain\vectorstores\mongodb_atlas.py) in
_similarity_search_with_score() sets the "filter" key to have the value
of the "pre_filter" argument.
```
params["filter"] = pre_filter
```
Test cases and documentation have also been added.

# Issue
#11616 

# Dependencies
No new dependencies have been added.

# Documentation
I have created the notebook mongodb_atlas_self_query.ipynb outlining the
steps to get the self-query mechanism working.

I worked closely with [@Farhan-Faisal](https://github.com/Farhan-Faisal)
on this PR.

Merriam-Webster Dictionary Tool (#12044)
# Description

We implemented a simple tool for accessing the Merriam-Webster
Collegiate Dictionary API
(https://dictionaryapi.com/products/api-collegiate-dictionary).

Here's a simple usage example:

```py
from langchain.llms import OpenAI
from langchain.agents import load_tools, initialize_agent, AgentType

llm = OpenAI()
tools = load_tools(["serpapi", "merriam-webster"], llm=llm) # Serp API gives our agent access to Google
agent = initialize_agent(
  tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True
)
agent.run("What is the english word for the german word Himbeere? Define that word.")
```

Sample output:

```
> Entering new AgentExecutor chain...
 I need to find the english word for Himbeere and then get the definition of that word.
Action: Search
Action Input: "English word for Himbeere"
Observation: {'type': 'translation_result'}
Thought: Now I have the english word, I can look up the definition.
Action: MerriamWebster
Action Input: raspberry
Observation: Definitions of 'raspberry':

1. rasp-ber-ry, noun: any of various usually black or red edible berries that are aggregate fruits consisting of numerous small drupes on a fleshy receptacle and that are usually rounder and smaller than the closely related blackberries
2. rasp-ber-ry, noun: a perennial plant (genus Rubus) of the rose family that bears raspberries
3. rasp-ber-ry, noun: a sound of contempt made by protruding the tongue between the lips and expelling air forcibly to produce a vibration; broadly : an expression of disapproval or contempt
4. black raspberry, noun: a raspberry (Rubus occidentalis) of eastern North America that has a purplish-black fruit and is the source of several cultivated varieties —called also blackcap

Thought: I now know the final answer.
Final Answer: Raspberry is an english word for Himbeere and it is defined as any of various usually black or red edible berries that are aggregate fruits consisting of numerous small drupes on a fleshy receptacle and that are usually rounder and smaller than the closely related blackberries.

> Finished chain.

introduce any new errors.

Our PR integrates the `praw` package which is already used by
RedditPostsLoader in LangChain. Nonetheless, we have added integration
tests and edited unit tests to test our changes. An example notebook is
also provided. These changes were put together by me, @Anika2000,
@CharlesXu123, and @Jeremy-Cheng-stack

update pdf document loaders' metadata source to url for online pdf (#13274)
- **Description:** Update 5 pdf document loaders in
`langchain.document_loaders.pdf`, to store a url in the metadata
(instead of a temporary, local file path) if the user provides a web
path to a pdf: `PyPDFium2Loader`, `PDFMinerLoader`,
`PDFMinerPDFasHTMLLoader`, `PyMuPDFLoader`, and `PDFPlumberLoader` were
updated.
- The updates follow the approach used to update `PyPDFLoader` for the
same behavior in #12092
- The `PyMuPDFLoader` changes required additional work in updating
`langchain.document_loaders.parsers.pdf.PyMuPDFParser` to be able to
process either an `io.BufferedReader` (from local pdf) or `io.BytesIO`
(from online pdf)
- The `PDFMinerPDFasHTMLLoader` change used a simpler approach since the
metadata is assigned by the loader and not the parser
  - **Issue:** Fixes #7034
  - **Dependencies:** None


```python
# PyPDFium2Loader example:
# old behavior
>>> from langchain.document_loaders import PyPDFium2Loader
>>> loader = PyPDFium2Loader('https://arxiv.org/pdf/1706.03762.pdf')

Also, since OpenAI only supports DALL-E version 2 or version 3, I
modified the DallEAPIWrapper to support it.

max length attribute for spacy splitter for large docs (#13875)
For large size documents spacy splitter doesn't work it throws an error
as shown in below screenshot.
Reason its default max_length is 1000000 and there is no option to
increase it. So i added it in this PR.

Repair Wikipedia document loader load_max_docs and improve test coverage. (#13769)
**Description:** 

Repair Wikipedia document loader `load_max_docs` and improve test
coverage.

**Issue:** 

The Wikipedia document loader was not respecting the `load_max_docs`
paramater (not reported) and would always return a maximum of 10
documents. This is because the API wrapper (in `utilities/wikipedia.py`)
wasn't passing `top_k_results` to the underlying [Wikipedia
library](https://wikipedia.readthedocs.io/en/latest/code.html#module-wikipedia).
By default this library returns 10 results.

The default number of results for the document loader has been reduced
from 100 to 25. This is because loading 100 results takes a very long
time and is an inconvenient default. It should possibly be 10.

In addition, the documentation for the loader reported that there was a
hard limit (300) on the number of documents returned. In actuality 300
is the maximum Wikipedia query character length set by the API wrapper.

Tests have been added for the document loader (previously missing) and
to test the correct numbers of documents are being returned by each
class, both by default, and when overridden. Also repaired is the
`assert_docs` test which has been updated to correctly test for the
default metadata (which includes `source` in recent releases).

Remove python_repl from _BASE_TOOLS (#13962)
### **Description:**

Previously `python_repl` was a built-in tool, but now it has been moved
to `langchain_experimental`.

When I use `load_tools` I get an error:

```python
In [1]: from langchain.agents import load_tools

In [2]: load_tools(["python_repl"])
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
Cell In[2], line 1
----> 1 load_tools(["python_repl"])

File ~/workspace/langchain/libs/langchain/langchain/agents/load_tools.py:530, in load_tools(tool_names, llm, callbacks, **kwargs)
    528     tool_names.extend(requests_method_tools)
    529 elif name in _BASE_TOOLS:
--> 530     tools.append(_BASE_TOOLS[name]())
    531 elif name in _LLM_TOOLS:
    532     if llm is None:

File ~/workspace/langchain/libs/langchain/langchain/agents/load_tools.py:84, in _get_python_repl()
     83 def _get_python_repl() -> BaseTool:
---> 84     raise ImportError(
     85         "This tool has been moved to langchain experiment. "
     86         "This tool has access to a python REPL. "
     87         "For best practices make sure to sandbox this tool. "
     88         "Read https://github.com/langchain-ai/langchain/blob/master/SECURITY.md "
     89         "To keep using this code as is, install langchain experimental and "
     90         "update relevant imports replacing 'langchain' with 'langchain_experimental'"
     91     )

ImportError: This tool has been moved to langchain experiment. This tool has access to a python REPL. For best practices make sure to sandbox this tool. Read https://github.com/langchain-ai/langchain/blob/master/SECURITY.md To keep using this code as is, install langchain experimental and update relevant imports replacing 'langchain' with 'langchain_experimental'
```

In this case, it will be very confusing. I think it is no longer a
built-in tool now, so it can be removed from `_BASE_TOOLS`

The `integrations/vectorstores/matchingengine.ipynb` example has the
"Google Vertex AI Vector Search" title. This place this Title in the
wrong order in the ToC (it is sorted by the file name).
- Renamed `integrations/vectorstores/matchingengine.ipynb` into
`integrations/vectorstores/google_vertex_ai_vector_search.ipynb`.
- Updated a correspondent comment in docstring
- Rerouted old URL to a new URL

experimental[patch]: fixed namespace bug (#13585)
It was :
`from langchain.schema.prompts import BasePromptTemplate`
but because of the breaking change in the ns, it is now
`from langchain.schema.prompt_template import BasePromptTemplate`

This bug prevents building the API Reference for the langchain_experimental
