 warnings.warn("PyTorch is not compiled with NCCL support")

Hi 

Thanks for your excellent work. I'm trying to run the loo_cross_validation.py code with your first example. But the train.py raised this error.

NCLL is not available on windows, so I tried to disable it with os.environ["PL_TORCH_DISTRIBUTED_BACKEND"] = "gloo", but the same error still exists.

Could anyone address this issue?

Thanks very much.
