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