When does this happen?
IF Some PyTorch operations are not implemented on MPS and raise errors, preventing training on Mac M1.
How others solved it
THEN Set the environment variable `PYTORCH_ENABLE_MPS_FALLBACK=1` before running your script. This causes unsupported operations to fall back to CPU, though a UserWarning will still appear.
export PYTORCH_ENABLE_MPS_FALLBACK=1
