Hello! How do I get rid of this when running torch? After getting this error the first time, I installed cmake, but I still get the error. I’m running cmake version 3.28.3 and torch version 2.3.1 on a basic droplet (Regular Intel CPU, 2vCPUs, 4 GB memory, 80 GB disk). Thanks!

Heya,
NNPACK needs AVX2 CPU instructions, so if these are not supported on your CPU, you would get this.
As such, what I could suggest is you could potentially build PyTorch from source without NNPACK to silence this warning or ignore it.
By looking at the forums I saw this:
