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

1. 问题描述

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

本机运行镜像容器报错：找不到GPU。通常问题在于执行程序需要GPU，但是镜像中是没有GPU的，只能调用本机的GPU。

2. 解决方法

1. 更新apt库，加载nvidia-docker(注意我这里是ubuntu18.04版本的)

$ curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
$ curl -s -L https://nvidia.github.io/nvidia-docker/ubuntu18.04/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
$ sudo apt-get update

2. 安装nvidia-docker2软件包并重新加载docker守护进程配置

$ sudo apt-get install nvidia-docker2
$ sudo pkill -SIGHUP dockerd
$ sudo systemctl restart docker

这里多说一句：在运行容器的时候调用GPU直接使用--gpus all即可
