nvidia-docker : Unknown runtime specified nvidia

问题

I tried to install the nvidia-docker after installing docker-ce. I followed this : https://github.com/NVIDIA/nvidia-docker to install nvidia-docker. It seems to have installed correctly.

I tried to run:

$ sudo docker run --runtime=nvidia --rm nvidia/cuda nvidia-smi
docker: Error response from daemon: Unknown runtime specified nvidia.
See 'docker run --help'.

Although, this works (without --runtime=nvidia):

$ docker container run -ti ubuntu bash

Some additional info on my system: It is an ubuntu server 16.04 with 8 GPUs (Titan Xp) and nvidia driver version 387.26. I can run nvidia-smi -l 1 on the host system and it works as expected.

$ dpkg -l | grep -E '(nvidia|docker)'

        }
    }
}

I have come across: https://github.com/NVIDIA/nvidia-docker/issues/501, but I am not sure how I should go about it.

回答1:

Actually, you can try to restart docker daemon by following command.

sudo systemctl daemon-reload
sudo systemctl restart docker

Or you can try to reboot your system. to make nvidia-docker work

回答2:

It seems you may need to purge docker and reinstall it as in the post: github issues

sudo apt remove docker-ce
sudo apt autoremove
sudo apt-get install docker-ce=5:18.09.0~3-0~ubuntu-bionic
sudo apt install nvidia-docker2
