This repository contains 1 package with Weaviate integrations with LangChain:
- langchain-weaviate integrates Weaviate.
langchain-weaviate supports faster vector math through the optional
simsimd library.
If simsimd is installed, cosine distance computations use the accelerated path.
If it is not installed, the package automatically falls back to a pure NumPy/SciPy implementation.
This makes simsimd truly optional and ensures the integration works in all environments
(including those with older glibc versions).
To install with the optional performance extra:
pip install "langchain-weaviate[simsimd]"
