Zachary Toliver	29ee0496b6	community[patch]: Allow override of 'fetch_schema_from_transport' in the GraphQL tool (#17649 ) - Description: In order to override the bool value of "fetch_schema_from_transport" in the GraphQLAPIWrapper, a "fetch_schema_from_transport" value needed to be added to the "_EXTRA_OPTIONAL_TOOLS" dictionary in load_tools in the "graphql" key. The parameter "fetch_schema_from_transport" must also be passed in to the GraphQLAPIWrapper to allow reading of the value when creating the client. Passing as an optional parameter is probably best to avoid breaking changes. This change is necessary to support GraphQL instances that do not support fetching schema, such as TigerGraph.

volodymyr-memsql	0a9a519a39	community[patch]: Added add_images method to SingleStoreDB vector store (#17871 ) In this pull request, we introduce the add_images method to the SingleStoreDB vector store class, expanding its capabilities to handle multi-modal embeddings seamlessly. This method facilitates the incorporation of image data into the vector store by associating each image's URI with corresponding document content, metadata, and either pre-generated embeddings or embeddings computed using the embed_image method of the provided embedding object. the change includes integration tests, validating the behavior of the add_images. Additionally, we provide a notebook showcasing the usage of this new method. --------- Co-authored-by: Volodymyr Tkachuk <vtkachuk-ua@singlestore.com>	7 months ago
Shashank	8381f859b4	community[patch]: Graceful handling of redis errors in RedisCache and AsyncRedisCache (#17171 ) - Description: The existing `RedisCache` implementation lacks proper handling for redis client failures, such as `ConnectionRefusedError`, leading to subsequent failures in pipeline components like LLM calls.

Raghav Dixit	6c18f73ca5	community[patch]: LanceDB integration improvements/fixes (#16173 ) Hi, I'm from the LanceDB team. Improves LanceDB integration by making it easier to use - now you aren't required to create tables manually and pass them in the constructor, although that is still backward compatible.

Stefano Lottini	5240ecab99	astradb: bootstrapping Astra DB as Partner Package (#16875 ) Description: This PR introduces a new "Astra DB" Partner Package. So far only the vector store class is _duplicated_ there, all others following once this is validated and established. Along with the move to separate package, incidentally, the class name will change `AstraDB` => `AstraDBVectorStore`. The strategy has been to duplicate the module (with prospected removal from community at LangChain 0.2). Until then, the code will be kept in sync with minimal, known differences (there is a makefile target to automate drift control. Out of convenience with this check, the community package has a class `AstraDBVectorStore` aliased to `AstraDB` at the end of the module). With this PR several bugfixes and improvement come to the vector store, as well as a reshuffling of the doc pages/notebooks (Astra and Cassandra) to align with the move to a separate package. Dependencies: A brand new pyproject.toml in the new package, no changes otherwise.

Kate Silverstein	0bc4a9b3fc	community[minor]: Adds Llamafile as an LLM (#17431 ) * Description: Adds a simple LLM implementation for interacting with [llamafile](https://github.com/Mozilla-Ocho/llamafile)-based models. * Dependencies: N/A * Issue: N/A Detail [llamafile](https://github.com/Mozilla-Ocho/llamafile) lets you run LLMs locally from a single file on most computers without installing any dependencies. To use the llamafile LLM implementation, the user needs to: 1. Download a llamafile e.g. https://huggingface.co/jartine/TinyLlama-1.1B-Chat-v1.0-GGUF/resolve/main/TinyLlama-1.1B-Chat-v1.0.Q5_K_M.llamafile?download=true 2. Make the file executable. 3. Run the llamafile in 'server mode'. (All llamafiles come packaged with a lightweight server; by default, the server listens at `http://localhost:8080`.) ```bash wget https://url/of/model.llamafile chmod +x model.llamafile ./model.llamafile --server --nobrowser ``` Now, the user can invoke the LLM via the LangChain client: ```python from langchain_community.llms.llamafile import Llamafile llm = Llamafile() llm.invoke("Tell me a joke.") ```	7 months ago
