mpb159753	7df2dfc4c2	Add Support for Loading Documents from Huawei OBS (#8573 ) Description: This PR adds support for loading documents from Huawei OBS (Object Storage Service) in Langchain. OBS is a cloud-based object storage service provided by Huawei Cloud. With this enhancement, Langchain users can now easily access and load documents stored in Huawei OBS directly into the system. Key Changes: - Added a new document loader module specifically for Huawei OBS integration. - Implemented the necessary logic to authenticate and connect to Huawei OBS using access credentials. - Enabled the loading of individual documents from a specified bucket and object key in Huawei OBS. - Provided the option to specify custom authentication information or obtain security tokens from Huawei Cloud ECS for easy access. How to Test: 1. Ensure the required package "esdk-obs-python" is installed. 2. Configure the endpoint, access key, secret key, and bucket details for Huawei OBS in the Langchain settings. 3. Load documents from Huawei OBS using the updated document loader module. 4. Verify that documents are successfully retrieved and loaded into Langchain for further processing. Please review this PR and let us know if any further improvements are needed. Your feedback is highly appreciated! @rlancemartin, @eyurtsev --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

Mohamad Zamini	3fbb737bb3	Update combined.py (#7541 ) from my understanding, the `check_repeated_memory_variable` validator will raise an error if any of the variables in the `memories` list are repeated. However, the `load_memory_variables` method does not check for repeated variables. This means that it is possible for the `CombinedMemory` instance to return a dictionary of memory variables that contains duplicate values. This code will check for repeated variables in the `data` dictionary returned by the `load_memory_variables` method of each sub-memory. If a repeated variable is found, an error will be raised. <!-- Thank you for contributing to LangChain!

Shantanu Nair	53f3793504	Fast load conversationsummarymemory from existing summary (#7533 ) - Description: Adds an optional buffer arg to the memory's from_messages() method. If provided the existing memory will be loaded instead of regenerating a summary from the loaded messages. Why? If we have past messages to load from, it is likely we also have an existing summary. This is particularly helpful in cases where the chat is ephemeral and/or is backed by serverless where the chat history is not stored but where the updated chat history is passed back and forth between a backend/frontend. Eg: Take a stateless qa backend implementation that loads messages on every request and generates a response — without this addition, each time the messages are loaded via from_messages, the summaries are recomputed even though they may have just been computed during the previous response. With this, the previously computed summary can be passed in and avoid: 1) spending extra $$$ on tokens, and 2) increased response time by avoiding regenerating previously generated summary.

Mohammad Mohtashim	144b4c0c78	SQL Query Prompt update + added _execute method for SQLDatabase (#8100 ) - Description: This pull request (PR) includes two minor changes: 1. Updated the default prompt for SQL Query Checker: The current prompt does not clearly specify the final response that the LLM (Language Model) should provide when checking for the query if `use_query_checker` is enabled in SQLDatabase Chain. As a result, the LLM adds extra words like "Here is your updated query" to the response. However, this causes a syntax error when executing the SQL command in SQLDatabaseChain, as these additional words are also included in the SQL query. 2. Moved the query's execution part into a separate method for SQLDatabase: The purpose of this change is to provide users with more flexibility when obtaining the result of an SQL query in the original form returned by sqlalchemy. In the previous implementation, the run method returned the results as a string. By creating a distinct method for execution, users can now receive the results in original format, which proves helpful in various scenarios. For example, during the development of a tool, I found it advantageous to obtain results in original format rather than a string, as currently done by the run method. - Tag maintainer: @hinthornw --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

os1ma	a795c3d860	Fix GitLoader to handle repeated load calls (#8412 ) Description: a description of the change In this pull request, GitLoader has been updated to handle multiple load calls, provided the same repository is being cloned. Previously, calling `load` multiple times would raise an error if a clone URL was provided. Additionally, a check has been added to raise a ValueError when attempting to clone a different repository into an existing path. New tests have also been introduced to verify the correct behavior of the GitLoader class when `load` is called multiple times. Lastly, the GitPython package, a dependency for the GitLoader class, has been added to the project dependencies (pyproject.toml and poetry.lock).

Muhammed Al-Dulaimi	9975ba4124	Fix ChromaDB integration -> docker container instructions (#8447 ) ## Description This PR handles modifying the Chroma DB integration's documentation. It modifies the Docker container example to fix the instructions mentioned in the documentation. In the current documentation, the below `client.reset()` line causes a runtime error: ```py ... client = chromadb.HttpClient(settings=Settings(allow_reset=True)) client.reset() # resets the database collection = client.create_collection("my_collection") ... ``` `Exception: {"error":"ValueError('Resetting is not allowed by this configuration')"}` This is due to the Chroma DB server needing to have the `allow_reset` flag set to `true` there as well. This is fixed by adding the `ALLOW_RESET=TRUE` to the `docker-compose` file environment variable to the docker container before spinning it ## Issue This fixes the runtime error that occurs when running the docker container example code ## Tag Maintainer @rlancemartin, @eyurtsev	1 year ago
