comet doesn't work when gpu=0

[leedrake5]

I am getting the error "multiprocessing_context can only be used with multi-process loading (num_workers > 0), but got num_workers=0" when trying to use compute with comet when gpus=0. This is a Mac M1 chip, so perhaps it isn't supported, even on a CPU basis?

Same issue. Mac M4.
