ubuntu 18.04 安装 nvidia-docker 教程

错误-显然是源仓库的版本不对-切记不要把16.04的源用在18.04的系统里：

nvidia-docker2 : Depends: docker-ce (= 5:18.09.3~3-0~ubuntu-xenial) but 5:18.09.3~3-0~ubuntu-bionic is to be installed or docker-ee (= 5:18.09.3~3-0~ubuntu-xenial) but it is not installable

解决：Docker Tutorial 5: Nvidia-Docker 2.0 Installation in Ubuntu 18.04

Differences between 1.0 and 2.0

When I decided to install nvidia-docker 2.0, I’ve just found most of the tutorials are talking about 1.0, and not much detailed tutorial for 2.0.

Before talking about the installation of nvidia-docker 2.0, I would like to mention about the difference between 1.0 and 2.0 first.

In the past, when we were using 1.0, another nvidia-docker daemon was used to replace docker to run the GPU image. And right now, with 2.0, we do not need to replace docker. Instead, we can choose to enable nvidia-docker at runtime in the command.

To know more details about the differences, you can have a look on
https://github.com/NVIDIA/nvidia-docker/wiki/About-version-2.0

Installation Procedures

Though I followed the installation guideline from NVIDIA, I got a little bit different procedures since I cannot install nvidia-docker 2.0 at the very beginning. Let’s see how I install it.

0. If there is nvidia-docker 1.0 already, it needs to be removed. (But I do not have it.)

docker volume ls -q -f driver=nvidia-docker | xargs -r -I{} -n1 docker ps -q -a -f volume={} | xargs -r docker rm -f
sudo apt-get purge nvidia-docker

Set the repository and update. I am using Ubuntu 18.04, so I follow the Debian settings:

curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | \
  sudo apt-key add -
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | \
  sudo tee /etc/apt/sources.list.d/nvidia-docker.list
sudo apt-get update
