I'm trying to follow this blog article to get CUDA working in a Ubuntu 20.04 kernel for non graphical machine learning running inside of WSL 2 under Windows 10 (build 20201.1000 with Nvidia driver 455.41) and am getting the error below for this command.
COMMAND: docker run --gpus all nvcr.io/nvidia/k8s/cuda-sample:nbody nbody -gpu -benchmarkRESPONSE: docker: Error response from daemon: could not select device driver "" with capabilities: [[gpu]].The blog posting itself and other research suggests that docker may need to be restarted to address this problem but unfortunately the commands from the same blog posting about stopping and starting docker don't quite work (the stop does but not the start).
The start command is stated to be sudo service docker stop but I get a response of docker: unrecognized service. Same thing if I try sudo service docker start which seems a more appropriate command to 'start' a service.
Note that I can get a list of services using sudo service --status-all but docker isn't listed. It is however there somewhere as docker --version works.
This other post suggested that the docker service may not be exposed or running. Pretty sure it's running as the wsl --shutdown Ubuntu command from the blog article results in a Windows docker notification that docker stopped unexpectedly with a 'do you want to restart it?'
Saying yes to that also doesn't help so my suspicion is it's not being exposed but don't know how to check.
