Nvidia Docker安装后，使用镜像创建容器时出错，命令如下

docker run -it -gpus all ubuntu nvidia-smi

错误提示：

Error response from daemon: could not select device driver "" with capabilities: [[gpu]]

这是由于没有配置好docker运行环境导致的，执行安装容器运行环境（Ubuntu为例）

apt-get install nvidia-container-toolkit

如果找不到，请添加

$ distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
$ curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
$ 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 && sudo apt-get install -y nvidia-container-toolkit
$ sudo systemctl restart docker

安装后重新启动docker

systemctl restart docker
