Train Error python train.py requested GPUs: [0]

[asbeg]

Hello,
I have followed your example to train NERF on my own data.

Im using MacOS based M1 Chip, does anyone have any idea what this might be related to. I can't figure out what's going on. Can you explain what the problem might be and how to fix it ? Thank you in advance for any help.

I am trying to run and get this error.
