Illegal instruction (core dumped) on py3.7 about faiss-wheels

@HaveF I could not reproduce your issue on my macbook pro. I suspect the cpu of the host hardware does not support certain set of instructions.

It's very weird.
But I successful run with python:3.8 on the same machine.
I also test on 3.7-stretch, failed.

Maybe something related with avx/avx2, and python 3.8 fix it?

Well, It seems use python 3.8 is the good choice.

Thanks for your time again
