Just to state the obvious, but for pip you can use gpu or cpu specifc builds:

pip install faiss-cpu

or

pip install faiss-gpu

Faiss on Pypi is only a collection of pre-built binaries for MacOS and Linux and only for these python versions:

Python :: 2.7 Python :: 3.5 Python :: 3.6 Python :: 3.7

Your setup does not seem to match these specifications

For conda, it does not exist in the std channels, but can be installed (for Linux and MacOS only) with:

conda install -c pytorch faiss-cpu

or

conda install -c pytorch faiss-gpu

You can install faiss on Windows. Go to the conda prompt and type:

conda install -c conda-forge faiss-cpu
