torch.distributed.elastic.multiprocessing.errors.ChildFailedError
when I run:
python -m torch.distributed.launch --nproc_per_node=2 ./tools/train.py configs/waymo/voxelnet/waymo_centerformer.py
It shows the following error:

This error message shows there is an issue in one subprocess. I have no idea what's wrong with it. Can you provide the environment you are running on and other output logs or error messages if there are any?
