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:

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.
