## Unofficial prebuilt binary for Linux and MacOS

## Original readme:

Faiss is a library for efficient similarity search and clustering of dense 
vectors. It contains algorithms that search in sets of vectors of any size,
 up to ones that possibly do not fit in RAM. It also contains supporting 
code for evaluation and parameter tuning. Faiss is written in C++ with 
complete wrappers for Python/numpy. Some of the most useful algorithms 
are implemented on the GPU. It is developed by Facebook AI Research.
