David vonThenen	40079d4936	Introduce Nebula LLM to LangChain (#8876 ) ## Description This PR adds Nebula to the available LLMs in LangChain. Nebula is an LLM focused on conversation understanding and enables users to extract conversation insights from video, audio, text, and chat-based conversations. These conversations can occur between any mix of human or AI participants. Examples of some questions you could ask Nebula from a given conversation are: - What could be the customer’s pain points based on the conversation? - What sales opportunities can be identified from this conversation? - What best practices can be derived from this conversation for future customer interactions? You can read more about Nebula here: https://symbl.ai/blog/extract-insights-symbl-ai-generative-ai-recall-ai-meetings/ #### Integration Test An integration test is added, but it requires network access. Since Nebula is fully managed like OpenAI, network access is required to exercise the integration test. #### Linting - [x] make lint - [x] make test (TODO: there seems to be a failure in another non-related test??? Need to check on this.) - [x] make format ### Dependencies No new dependencies were introduced. ### Twitter handle [@symbldotai](https://twitter.com/symbldotai) [@dvonthenen](https://twitter.com/dvonthenen) If you have any questions, please let me know. cc: @hwchase17, @baskaryan --------- Co-authored-by: dvonthenen <david.vonthenen@gmail.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

We have recently added [Xata to Langchain.js](https://github.com/hwchase17/langchainjs/pull/2125) and would love to have the equivalent in the Python project as well. The PR includes integration tests and a Jupyter notebook as docs. Please let me know if anything else would be needed or helpful. I have added the xata python SDK as an optional dependency. ## To run the integration tests You will need to create a DB in xata (see the docs), then run something like: ``` OPENAI_API_KEY=sk-...

This PR closes #8729. This feature clearly depends on `vllm`, but I've seen other models supported here depend on packages that are not included in the pyproject.toml (e.g. `gpt4all`, `text-generation`) so I thought it was the case for this as well. @hwchase17, @baskaryan --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	1 year ago

Tesfagabir Meharizghi	a7000ee89e	Callback handler for Amazon SageMaker Experiments (#8587 ) ## Description This PR implements a callback handler for SageMaker Experiments which is similar to that of mlflow. * When creating the callback handler, it takes the experiment's run object as an argument. All the callback outputs are then logged to the run object. * The output of each callback action (e.g., `on_llm_start`) is saved to S3 bucket as json file. * Optionally, you can also log additional information such as the LLM hyper-parameters to the same run object. * Once the callback object is no more needed, you will need to call the `flush_tracker()` method. This makes sure that any intermediate files are deleted. * A separate notebook example is provided to show how the callback is used. @3coins @agola11 --------- Co-authored-by: Tesfagabir Meharizghi <mehariz@amazon.com>	1 year ago
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

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.

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
