Multi GPU usage on Windows

[robinvetsch]

Hi all,

I have installed Isaac Sim 2022.2.1 including OmniIsaacGym on a Windows machine. The PC has two A6000 RTX graphics cards, both of which I want to use. To test this I wanted to run the example from the repository with the following command.

PYTHON_PATH -m torch.distributed.run --nnodes=1 --nproc_per_node=2 scripts/rlgames_train.py headless=True task=Ant multi_gpu=True

After starting I get the following error:

Can anyone help me?

Many thanks
