Unable to create renderer: NVIDIA GPU supporting RTX Ray

Hi. Welcome to the Forums.

It looks like you are using the old nvidia docker. Please take a look at the new NVIDIA Container Toolkit. You can do a fresh install or upgrade from nvidia-docker2. Please test if the install works by running:

docker run --gpus all nvidia/cuda:10.0-base nvidia-smi

You should then run with:
docker run --gpus all -e "ACCEPT_EULA=Y" --rm -p 47995-48012:47995-48012/udp -p 47995-48012:47995-48012/tcp -p 49000-49007:49000-49007/tcp -p 49000-49007:49000-49007/udp nvcr.io/nvidia/isaac-sim:2020.1_ea

Note:
–gpus all: to use all available gpus
–gpus '“device=0”: to use specific gpu device (device 0)
