langchain.vectorstores.faiss.dependable_faiss_import(no_avx2: Optional[bool] = None) → Any

Import faiss if available, otherwise raise error. If FAISS_NO_AVX2 environment variable is set, it will be considered to load FAISS with no AVX2 optimization.

Parameters

no_avx2 – Load FAISS strictly with no AVX2 optimization so that the vectorstore is portable and compatible with other devices.
