There appears to be a bug with 19.13 AVX detection when using python setup. Attempting to compile on a Celeron N3160 show that AVX is supported by the CPU. However, the N3160 does not support AVX.
Thanks in advance,

It continues to compile. But running it, results in a core dump. I'm sure the dump is a result of AVX as I had this issue before in an earlier build. Once I disabled AVX, it was fine. I've since gotten an i3 as my testbed, but wanted you to know of the potential issue with AVX auto detection. Of course, I'm happy to test any solution you may have in auto detecting.

Apologies for the late response... I cloned the latest from github and went through the build process. AVX is no longer detected on the N3160! Thanks Davis.

What happens exactly?

Sure. When you go into the dlib/cmake_utils/test_for_avx folder and run
cmake . what does it output?
Also make sure you are using the latest dlib from github. It's possible
that this has been fixed already.

No worries, thanks for the update!
You're welcome. Thank you for dlib!
