I have the same issue.
I have looked through procmon, it seems flang.dll and flangrti.dll cannot be found.

How to fix it manually:

1. Download the following archives:
   https://anaconda.org/conda-forge/libflang/5.0.0/download/win-64/libflang-5.0.0-h6538335_20180525.tar.bz2
   https://anaconda.org/conda-forge/openmp/7.0.0/download/win-64/openmp-7.0.0-h1ad3211_0.tar.bz2

2. Unpack and copy the following dll files to site-packages\faiss directory:

flang.dll
flangrti.dll
libomp.dll
ompstub.dll

I think these missing dll files should be inside whl.

Still throwing an error like
ImportError: DLL load failed: The specified module could not be found.

Unpacking those dlls still doesn't solve the problem.
