nvidia-docker not working on xavier

I have my xavier flashed with jetpack 4.2.1. It is mentioned in the Release note of jetpack that it has new feature of: NVIDIA Container Runtime with Docker integration.

when I pull and try to run image it gives me following error:

sudo nvidia-docker run --runtime=nvidia --rm nvidia/cuda nvidia-smi

docker: Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused “exec: “nvidia-smi”: executable file not found in $PATH”: unknown.

So is nvidia-docker supported on xavier or not ?

and if it is mentioned in the release note then why it is not working ?

Can somebody please help me?

probably you would rather use Jetpack 4.2.2 for the container feature
