This PR adds support for metadata filters of the form:
`{"filter": {"key": { "NIN" : ["list", "of", "values"]}}}`
"IN" is already supported, so this is a quick & related update to add
"NIN"
- **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.

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 :)
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.
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.

Allow users to pass a generic `BaseStore[str, bytes]` to

**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.
If we are not going to make the existing Docstore class also implement
`BaseStore[str, Document]`, IMO all base store implementations should
always be `[str, bytes]` so that they are more interchangeable.

### 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"])

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.

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.
Best,

- **Description:** Fixes the Mathpix PDF loader API integration.
Specifically, ensures that Mathpix auth headers are provided for every
request, and ensures that we recognize all errors that can occur during
a request. Also, the option to provide API keys as kwargs never actually
worked before, but now that's fixed too.
- **Issue:** #11249

- **Description:**
This PR introduces the Slack toolkit to LangChain, which allows users to
read and write to Slack using the Slack API. Specifically, we've added
the following tools.
1. get_channel: Provides a summary of all the channels in a workspace.
2. get_message: Gets the message history of a channel.
3. send_message: Sends a message to a channel.
4. schedule_message: Sends a message to a channel at a specific time and
date.
- **Issue:** This pull request addresses [Add Slack Toolkit
#11747](https://github.com/langchain-ai/langchain/issues/11747)
- **Dependencies:** package`slack_sdk`
Note: For this toolkit to function you will need to add a Slack app to
your workspace. Additional info can be found
[here](https://slack.com/help/articles/202035138-Add-apps-to-your-Slack-workspace).

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.**
reference link: [Shallow vs Deep Copying of Python
Objects](https://realpython.com/copying-python-objects/)
Thanks! ☺️
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)
```
This PR adds an "Azure AI data" document loader, which allows Azure AI
users to load their registered data assets as a document object in
langchain.

* 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

**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.
Description
when the desc of arg in python docstring contains ":", the
`_parse_python_function_docstring` will raise **ValueError: too many
values to unpack (expected 2)**.
A sample desc would be:
"""
Args:
error_arg: this is an arg with an additional ":" symbol
"""
So, set `maxsplit` parameter to fix it.
The number of times I try to format a string (especially in lcel) is
embarrassingly high. Think this may be more actionable than the default
error message. Now I get nice helpful errors
```
KeyError: "Input to ChatPromptTemplate is missing variable 'input'. Expected: ['input'] Received: ['dialogue']"
```
**Description:** By combining the document timestamp refresh within a
single call to update(), this enables batching of multiple documents in
a single SQL statement. This is important for non-local databases where
tens of milliseconds has a huge impact on performance when doing

…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! ☺️
