If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker ricar

Remember that you will have to log out and back in for this to take effect!

WARNING: Adding a user to the "docker" group will grant the ability to run
         containers which can be used to obtain root privileges on the
         docker host.
         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
         for more information.

I am having exactly the same problem.

Other images in the samples repo works though. For example:

docker run --rm --gpus all nvcr.io/nvidia/k8s/cuda-sample:vectoradd-cuda10.2

Looks like driver is behind, Does the 470.14 driver support CUDA 11?

yes,i have passed cuda10.2 either,shou i install cuda tookit==10.2?

my windwos CUDA version is 10.1.243,should i update to >=11.2?
