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)
```

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)

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

```
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。")

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 :)

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.

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"])
    ...:

Fix Azure Openai function calling in streaming mode (#13768)
- **Description**: This PR addresses an issue with the OpenAI API
streaming response, where initially the key (arguments) is provided but
the value is None. Subsequently, it updates with {"arguments": "{\n"},
leading to a type inconsistency that causes an exception. The specific
error encountered is ValueError: additional_kwargs["arguments"] already
exists in this message, but with a different type. This change aims to
resolve this inconsistency and ensure smooth API interactions.
- **Issue**: None.
- **Dependencies**: None.

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.

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.**

Jeremy Naccache a14cf87576
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:**

- https://github.com/langchain-ai/langchain/issues/11532

**Dependencies:**

No additional dependencies :)

**Tag maintainer:**

@baskaryan 

**Twitter handle:**

No need. :)

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.

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')
>>> docs = loader.load()
>>> docs[0].metadata
{'source': '/var/folders/7z/d5dt407n673drh1f5cm8spj40000gn/T/tmpm5oqa92f/tmp.pdf', 'page': 0}

# new behavior
>>> from langchain.document_loaders import PyPDFium2Loader
>>> loader = PyPDFium2Loader('https://arxiv.org/pdf/1706.03762.pdf')
>>> docs = loader.load()
>>> docs[0].metadata
{'source': 'https://arxiv.org/pdf/1706.03762.pdf', 'page': 0}

langchain[minor]: Reduce the number of tokens required to describe a Cypher/Neo4j schema (#13851)
Instead of using JSON-like syntax to describe node and relationship
properties we changed to a shorter and more concise schema description

Old:

```
        Node properties are the following:
        [{'properties': [{'property': 'name', 'type': 'STRING'}], 'labels': 'Movie'}, {'properties': [{'property': 'name', 'type': 'STRING'}], 'labels': 'Actor'}]
        Relationship properties are the following:
        []
        The relationships are the following:
        ['(:Actor)-[:ACTED_IN]->(:Movie)']
```

New:

```
Node properties are the following:
Movie {name: STRING},Actor {name: STRING}
Relationship properties are the following:

The relationships are the following:
(:Actor)-[:ACTED_IN]->(:Movie)

langchain[minor]: Add StackExchange API integration (#14002)
Implements
[#12115](https://github.com/langchain-ai/langchain/issues/12115)

Who can review?
@baskaryan , @eyurtsev , @hwchase17 

Integrated Stack Exchange API into Langchain, enabling access to diverse
communities within the platform. This addition enhances Langchain's
capabilities by allowing users to query Stack Exchange for specialized
information and engage in discussions. The integration provides seamless
interaction with Stack Exchange content, offering content from varied
knowledge repositories.

A notebook example and test cases were included to demonstrate the
functionality and reliability of this integration.

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:

     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`

langchain[minor]: Updated DocugamiLoader, includes breaking changes (#13265)
There are the following main changes in this PR:

1. Rewrite of the DocugamiLoader to not do any XML parsing of the DGML
format internally, and instead use the `dgml-utils` library we are
separately working on. This is a very lightweight dependency.
2. Added MMR search type as an option to multi-vector retriever, similar
to other retrievers. MMR is especially useful when using Docugami for
RAG since we deal with large sets of documents within which a few might
be duplicates and straight similarity based search doesn't give great
results in many cases.

We are @docugami on twitter, and I am @tjaffri

langchain[minor]: Adding `infinity` embedding integration. (#13928)
This adds integation to https://github.com/michaelfeil/infinity. Users
requested it in https://github.com/michaelfeil/infinity/issues/36
@saatvikshah

Follows my implementation of gradient.ai.

Feedback 1: Well done - I love your CI / repo / poetry setup - I adapted
a lot in https://github.com/michaelfeil/infinity.
Feedback 2: Not so good: The openai integration contains to much reverse
engineering - in general projects such as michaelfeil/infinity and
huggingface/text-embeddings-inference are compatible to the `pip install
openai` package.

Reverse engineering like this one is really hindering the use for me:

8e88ba16a8/libs/langchain/langchain/embeddings/openai.py (L347)

8e88ba16a8/libs/langchain/langchain/embeddings/openai.py (L351)
- it is about preventing 3rd party providers to use the same url + uses
interfaces of openai, that are not publically documented.

experimental[patch]: Add experimental.agent imports (#13839)
- **Description:** The experimental package needs to be compatible with
the usage of importing agents

For example, if i use `from langchain.agents import
create_pandas_dataframe_agent`, running the program will prompt the
following information:

```
Traceback (most recent call last):
   File "/Users/dongwm/test/main.py", line 1, in <module>
     from langchain.agents import create_pandas_dataframe_agent
   File "/Users/dongwm/test/venv/lib/python3.11/site-packages/langchain/agents/__init__.py", line 87, in __getattr__
     raise ImportError(
ImportError: create_pandas_dataframe_agent has been moved to langchain experimental. See https://github.com/langchain-ai/langchain/discussions/11680 for more information.
Please update your import statement from: `langchain.agents.create_pandas_dataframe_agent` to `langchain_experimental.agents.create_pandas_dataframe_agent`.
```

But when I changed to `from langchain_experimental.agents import
create_pandas_dataframe_agent`, it was actually wrong:

```python
Traceback (most recent call last):
  File "/Users/dongwm/test/main.py", line 2, in <module>
    from langchain_experimental.agents import create_pandas_dataframe_agent
ImportError: cannot import name 'create_pandas_dataframe_agent' from 'langchain_experimental.agents' (/Users/dongwm/test/venv/lib/python3.11/site-packages/langchain_experimental/agents/__init__.py)
```

I should use `from langchain_experimental.agents.agent_toolkits import
create_pandas_dataframe_agent`. In order to solve the problem and make
it compatible, I added additional import code to the
langchain_experimental package. Now it can be like this Used `from
langchain_experimental.agents import create_pandas_dataframe_agent`

langchain[patch]: Add progress bar option to OllamaEmbeddings (#13882)
- **Description:** Adds a tqdm progress bar to OllamaEmbeddings when
embedding a list.
- **Issue:** Related to #13637, but extended to Ollama.
- **Dependencies:** `tqdm` made a necessary dependency.

Thanks to @ugm2 for helping identify a common problem. Embeddings take a
very long time to finish on local machines, and require a progress bar
to help identify if one should even attempt the workload.

DOCS: fixed error in the docstring of RunnablePassthrough class (#13843)
This pull request addresses an issue found in the example code within
the docstring of `libs/core/langchain_core/runnables/passthrough.py`

The original code snippet caused a `NameError` due to the missing import
of `RunnableLambda`. The error was as follows:
```
     12     return "completion"
     13 
---> 14 chain = RunnableLambda(fake_llm) | {
     15     'original': RunnablePassthrough(), # Original LLM output
     16     'parsed': lambda text: text[::-1] # Parsing logic

NameError: name 'RunnableLambda' is not defined
```
To resolve this, I have modified the example code to include the
necessary import statement for `RunnableLambda`. Additionally, I have
adjusted the indentation in the code snippet to ensure consistency and
readability.

The modified code now successfully defines and utilizes
`RunnableLambda`, ensuring that users referencing the docstring will
have a functional and clear example to follow.

There are no related GitHub issues for this particular change.

Modified Code:
```python
from langchain_core.runnables import RunnablePassthrough, RunnableParallel
from langchain_core.runnables import RunnableLambda

runnable = RunnableParallel(
    origin=RunnablePassthrough(),
    modified=lambda x: x+1
)

runnable.invoke(1) # {'origin': 1, 'modified': 2}

def fake_llm(prompt: str) -> str: # Fake LLM for the example
    return "completion"

chain = RunnableLambda(fake_llm) | {
    'original': RunnablePassthrough(), # Original LLM output
    'parsed': lambda text: text[::-1] # Parsing logic
}

chain.invoke('hello') # {'original': 'completion', 'parsed': 'noitelpmoc'}
```

FEATURE: Astra DB, LLM cache classes (exact-match and semantic cache) (#13834)
This PR provides idiomatic implementations for the exact-match and the
semantic LLM caches using Astra DB as backend through the database's
HTTP JSON API. These caches require the `astrapy` library as dependency.

Comes with integration tests and example usage in the `llm_cache.ipynb`
in the docs.

@baskaryan this is the Astra DB counterpart for the Cassandra classes
you merged some time ago, tagging you for your familiarity with the

VertexAI LLM count_tokens method requires list of prompts (#13451)
I encountered this during summarization with VertexAI. I was receiving
an INVALID_ARGUMENT error, as it was trying to send a list of about
17000 single characters.

The [count_tokens
method](https://github.com/googleapis/python-aiplatform/blob/main/vertexai/language_models/_language_models.py#L658)
made available by Google takes in a list of prompts. It does not fail
for small texts, but it does for longer documents because the argument
list will be exceeding Googles allowed limit. Enforcing the list type
makes it work successfully.

This change will cast the input text to count to a list of that single
text so that the input format is always correct.

feat: add ERNIE-Bot-4 Function Calling (#13320)
- **Description:** ERNIE-Bot-Chat-4 Large Language Model adds the
ability of `Function Calling` by passing parameters through the
`functions` parameter in the request. To simplify function calling for
ERNIE-Bot-Chat-4, the `create_ernie_fn_chain()` function has been added.
The definition and usage of the `create_ernie_fn_chain()` function is
similar to that of the `create_openai_fn_chain()` function.

Examples as the follows:

```
import json

from langchain.chains.ernie_functions import (
    create_ernie_fn_chain,
)
from langchain.chat_models import ErnieBotChat
from langchain.prompts import ChatPromptTemplate

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)

llm = ErnieBotChat(model_name="ERNIE-Bot-4")
prompt = ChatPromptTemplate.from_messages(
    [
        ("human", "{query}"),
    ]
)

chain = create_ernie_fn_chain([get_current_weather, get_current_news], llm, prompt, verbose=True)
res = chain.run("北京今天的新闻是什么?")
print(res)
```

The running results of the above program are shown below:
```
> Entering new LLMChain chain...
Prompt after formatting:
Human: 北京今天的新闻是什么?



> Finished chain.
{'name': 'get_current_news', 'thoughts': '用户想要知道北京今天的新闻。我可以使用get_current_news工具来获取这些信息。', 'arguments': {'location': '北京'}}

Fix tool arguments formatting in StructuredChatAgent (#10480)
In the `FORMAT_INSTRUCTIONS` template, 4 curly braces (escaping) are
used to get single curly brace after formatting:

```
"{{{ ... }}}}" -> format_instructions.format() ->  "{{ ... }}" -> template.format() -> "{ ... }".
```

Tool's `args_schema` string contains single braces `{ ... }`, and is
also transformed to `{{{{ ... }}}}` form. But this is not really correct
since there is only one `format()` call:

```
"{{{{ ... }}}}" -> template.format() -> "{{ ... }}".
```

As a result we get double curly braces in the prompt:
````
Respond to the human as helpfully and accurately as possible. You have access to the following tools:

foo: Test tool FOO, args: {{'tool_input': {{'type': 'string'}}}}    # <--- !!!
...
Provide only ONE action per $JSON_BLOB, as shown:

```
{
  "action": $TOOL_NAME,
  "action_input": $INPUT
}
```
````

This PR fixes curly braces escaping in the `args_schema` to have single
braces in the final prompt:
````
Respond to the human as helpfully and accurately as possible. You have access to the following tools:

foo: Test tool FOO, args: {'tool_input': {'type': 'string'}}    # <--- !!!
...
Provide only ONE action per $JSON_BLOB, as shown:

```
{
  "action": $TOOL_NAME,
  "action_input": $INPUT
}
```

BUG: Limit Azure OpenAI embeddings chunk size (#13425)
Hi! 
This short PR aims at:
* Fixing `OpenAIEmbeddings`' check on `chunk_size` when used with Azure
OpenAI (thus with openai < 1.0). Azure OpenAI embeddings support at most
16 chunks per batch, I believe we are supposed to take the min between
the passed value/default value and 16, not the max - which, I suppose,
was introduced by accident while refactoring the previous version of
this check from this other PR of mine: #10707
* Porting this fix to the newest class (`AzureOpenAIEmbeddings`) for
openai >= 1.0

This fixes #13539 (closed but the issue persists).

EXPERIMENTAL Generic LLM wrapper to support chat model interface with configurable chat prompt format (#8295)
## Update 2023-09-08

This PR now supports further models in addition to Lllama-2 chat models.
See [this comment](#issuecomment-1668988543) for further details. The
title of this PR has been updated accordingly.

## Original PR description

This PR adds a generic `Llama2Chat` model, a wrapper for LLMs able to
serve Llama-2 chat models (like `LlamaCPP`,
`HuggingFaceTextGenInference`, ...). It implements `BaseChatModel`,
converts a list of chat messages into the [required Llama-2 chat prompt
format](https://huggingface.co/blog/llama2#how-to-prompt-llama-2) and
forwards the formatted prompt as `str` to the wrapped `LLM`. Usage
example:

```python
# uses a locally hosted Llama2 chat model
llm = HuggingFaceTextGenInference(
    inference_server_url="http://127.0.0.1:8080/",
    max_new_tokens=512,
    top_k=50,
    temperature=0.1,
    repetition_penalty=1.03,
)

# Wrap llm to support Llama2 chat prompt format.
# Resulting model is a chat model
model = Llama2Chat(llm=llm)

messages = [
    SystemMessage(content="You are a helpful assistant."),
    MessagesPlaceholder(variable_name="chat_history"),
    HumanMessagePromptTemplate.from_template("{text}"),
]

prompt = ChatPromptTemplate.from_messages(messages)
memory = ConversationBufferMemory(memory_key="chat_history", return_messages=True)
chain = LLMChain(llm=model, prompt=prompt, memory=memory)

# use chat model in a conversation
# ...
```

Also part of this PR are tests and a demo notebook.

IMPROVEMENT Neptune graph updates (#13491)
## Description
This PR adds an option to allow unsigned requests to the Neptune
database when using the `NeptuneGraph` class.

```python
graph = NeptuneGraph(
    host='<my-cluster>',
    port=8182,
    sign=False
)
```

Also, added is an option in the `NeptuneOpenCypherQAChain` to provide
additional domain instructions to the graph query generation prompt.
This will be injected in the prompt as-is, so you should include any
provider specific tags, for example `<instructions>` or `<INSTR>`.

```python
chain = NeptuneOpenCypherQAChain.from_llm(
    llm=llm,
    graph=graph,
    extra_instructions="""
    Follow these instructions to build the query:
    1. Countries contain airports, not the other way around
    2. Use the airport code for identifying airports

Astra DB: minor improvements to docstrings and demo notebook (#13449)
This PR brings a few minor improvements to the docs, namely class/method
docstrings and the demo notebook.

- A note on how to control concurrency levels to tune performance in
bulk inserts, both in the class docstring and the demo notebook;
- Slightly increased concurrency defaults after careful experimentation
(still on the conservative side even for clients running on
less-than-typical network/hardware specs)
- renamed the DB token variable to the standardized
`ASTRA_DB_APPLICATION_TOKEN` name (used elsewhere, e.g. in the Astra DB
docs)
- added a note and a reference (add_text docstring, demo notebook) on
allowed metadata field names.

IMPROVEMENT Increase flexibility of ElasticVectorSearch (#6863)
Hey @rlancemartin, @eyurtsev ,

I did some minimal changes to the `ElasticVectorSearch` client so that
it plays better with existing ES indices.

Main changes are as follows:

1. You can pass the dense vector field name into `_default_script_query`
2. You can pass a custom script query implementation and the respective
parameters to `similarity_search_with_score`
3. You can pass functions for building page content and metadata for the
resulting `Document`

hi!
This is pretty straight-forward: The sdist package does not contain the
license file (which is needed by e.g. conda) because the package is
built from the subdir and can't see the license.
I _copied_ the license but since I'm unfamiliar with the projects
direction, I'm not sure that's correct.
thanks!

Fix Pinecone cosine relevance score (#8920)
Fixes: #8207

Description:
Pinecone returns scores (not distances) with cosine similarity. The
values according to the docs are [-1, 1], although I could never
reproduce negative values.

This PR ensures that the score returned from Pinecone is preserved,
rather than inverted, so the most relevant documents can be filtered (eg
when using similarity thresholds)

I'll leave this as a draft PR as I couldn't run the tests (my pinecone
account might not be enough - some errors were being thrown around
namespaces) so hopefully someone who _can_ will pick this up.

Maintainers:
@rlancemartin, @eyurtsev

chore: bump momento dependency version and refactor search hit usage (#13111)
**Description**

Bumps the Momento dependency to the latest version and refactors the
usage of `SearchHit` in the Momento Vector Index (MVI) vector store
integration. This change is a one liner where we use the preferred
attribute `score` to read the query-document similarity instead of
`distance`. The latest versions of Momento clients will use this
attribute going forward.

**Dependencies**

Updated the Momento dependency to latest version.

**Tests**

💚 I re-ran the existing MVI integration tests
(`tests/integration_tests/vectorstores/test_momento_vector_index.py`)
and they pass.

Improve CSV reader which can't call .strip() on NoneType (#13079)
Improve CSV reader which can't call .strip() on NoneType if there are
less cells in the row compared to the header

<!-- Thank you for contributing to LangChain!

Replace this entire comment with:
  - **Description:** 
I have a CSV file as followed

```
headerA,headerB,headerC
v1A,v1B,v1C,
v2A,v2B
v3A,v3B,v3C
```
In this case, row 2 is missing a value, which results in reading a None
type. The strip() method can not be called on None, hence raising. In
this PR I am making the change to only call strip if the value if not
None.

I had to implement this for working with the Ionic documentation, and

SitemapLoader was in the spirit of a proper feature for the library --
but I'm grateful for the opportunities Langchain has given me and I'd
love to build this out properly for the sake of the community.

Don't pass EF to chroma (#13085)
- **Description:** 

Recently Chroma rolled out a breaking change on the way we handle
embedding functions, in order to support multi-modal collections.

This broke the way LangChain's `Chroma` objects get created, because we
were passing the EF down into the Chroma collection:
https://docs.trychroma.com/migration#migration-to-0416---november-7-2023

However, internally, we are never actually using embeddings on the
chroma collection - LangChain's `Chroma` object calls it instead. Thus
we just don't pass an `embedding_function` to Chroma itself, which fixes
the issue.

Add "Astra DB" vector store integration (#12966)
# Astra DB Vector store integration

- **Description:** This PR adds a `VectorStore` implementation for
DataStax Astra DB using its HTTP API
  - **Issue:** (no related issue)
- **Dependencies:** A new required dependency is `astrapy` (`>=0.5.3`)
which was added to pyptoject.toml, optional, as per guidelines
- **Tag maintainer:** I recently mentioned to @baskaryan this
integration was coming
  - **Twitter handle:** `@rsprrs` if you want to mention me

This PR introduces the `AstraDB` vector store class, extensive
integration test coverage, a reworking of the documentation which
conflates Cassandra and Astra DB on a single "provider" page and a new,
completely reworked vector-store example notebook (common to the
Cassandra store, since parts of the flow is shared by the two APIs). I
also took care in ensuring docs (and redirects therein) are behaving
correctly.

All style, linting, typechecks and tests pass as far as the `AstraDB`
integration is concerned.

I could build the documentation and check it all right (but ran into
trouble with the `api_docs_build` makefile target which I could not
verify: `Error: Unable to import module
'plan_and_execute.agent_executor' with error: No module named
'langchain_experimental'` was the first of many similar errors)

Thank you for a review!
Stefano
