📄 Description

We build the GPU libraries with AVX enabled to ensure that if not all layers fit on the GPU we get better performance in a mixed mode. If the user is using a virtualization/emulation system that lacks AVX this used to result in an illegal instruction error and crash before this fix. Now we will report a warning in the server log, and just use CPU mode to ensure we don't crash.

This should mitigate #2187.
