Pytorch 1.8 and above with no CUDA on Mac OS?

Hi everyone! I am a beginner. I am trying to instal pytorch 1.8 (at least) with no CUDA on Mac OS Big Sur. But no matter what I do, I keep on getting the version 1.7.1. I use conda. The problem is that this version seems to have outdated tensor algebra modules, like for instance fft doesn’t have fftfreq. Thanks in advance!
