`faiss` fails to import on python==3.12 because of deprecated `numpy.distutils`

[GaetanLepage]

Summary

To know whether the system supports SVE, faiss uses deprecated numpy.distutils.cpuinfo. This has been removed and crashes on Python 3.12 (on aarch64-linux systems) with:

acked, Nix is not the official supported way of installing faiss. If you need to be unblocked quickly, can you try installing faiss from conda-forge? I will check if https://anaconda.org/anaconda/py-cpuinfo can be used to replace the deprecated module

I am not a faiss user myself. I do maintenance on the python ecosystem within nixpkgs. For now, we have patched it by inserting a return False statement before the problematic import statement.

There is no particular urgency don't worry.

I am also facing this exact same issue using Debian. Specifically, installing faiss in a Docker container based on python:3.12-slim-bookworm.

[mengdilin]

@cachitas is this on x86 or aarch64?

[cachitas]

aarch64

[asadoughi]

This doesn't appear to be aarch64 specific: based on the numpy documentation it applies to all numpy uses in Python 3.12 and newer.
