Not able to run main.py on m1 chipped machine

[alicezou]

Hi, I got assertion error on m1 chipped machine. I git clone directly from the main branch. I was able to run on my other computers or google coLab.

Attached is the log that I got: 2021-11-10 13:30:51 alicezous-Mac-mini.local main[11455] INFO Loading OthelloGame... 2021-11-10 13:30:51 alicezous-Mac-mini.local main[11455] INFO Loading NNetWrapper... 2021-11-10 13:30:51 alicezous-Mac-mini.local main[11455] WARNING Not loading a checkpoint! 2021-11-10 13:30:51 alicezous-Mac-mini.local main[11455] INFO Loading the Coach... 2021-11-10 13:30:51 alicezous-Mac-mini.local main[11455] INFO Starting the learning process 🎉 2021-11-10 13:30:51 alicezous-Mac-mini.local Coach[11455] INFO Starting Iter #1 ...

[dweekly]

This may have been fixed; I'm able to run just fine on an M1 in the current build, though not with pytorch's new mps device support.
