Hello,
I try to use multiple GPUs (RTX 2080Ti *2) with torch.distributed and pytorch-lightning on WSL2 (windows subsystem for linux).
But I receiving following error:
NCCL error in: /pytorch/torch/lib/c10d/ProcessGroupNCCL.cpp:518, unhandled system error, NCCL version 2.4.8

I can run same process using single GPU.
Thanks for your great help.
