Cannot connect to the Docker daemon at unix:///var/run/docker.sock

Hi @wangmaolin , I ran into a docker error while running your codes:

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
docker: invalid reference format: repository name must be lowercase.

Is it possible I build the code solely with pytorch?
Thank you very much.

I think this error is related to the docker installation as it reported about the docker daemon is not running. Please try a hello world example to verify the required NVIDIA docker is properly installed.
