docker - Docker 容器中的 nvidia-docker GPU

Question

我正在尝试复制需要我遵循 this particular tutorial on setting up Jupyter + Tensorflow + Nvidia GPU + Docker + Google Compute Engine 的工作/实验. '

我可以成功安装nvidia-docker .然而，在 tutorial ，在 Verify the GPU is Visible from a Docker Container 部分下，当我尝试运行时

sudo nvidia-docker-plugin

我收到以下错误(见最后一行):

nvidia-docker-plugin | 2019/04/23 15:17:47 Loading NVIDIA unified memory
nvidia-docker-plugin | 2019/04/23 15:17:47 Loading NVIDIA management library

nvidia-docker-plugin | 2019/04/23 15:17:47 Error: listen tcp 127.0.0.1:3476: bind: address already in use

当我运行时

sudo nvidia-docker run --rm nvidia/cuda nvidia-smi

我碰巧得到以下 executable file not found in $PATH": unknown错误:

docker: Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"nvidia-smi\": executable file not found in $PATH": unknown.
ERRO[0000] error waiting for container: context canceled 

我对 docker 很陌生；因此，如果有人可以帮助我完成解决方案，那就太好了。我试过搜索 for answers ，但解决问题的实际过程却让我望而却步。任何帮助将不胜感激。

编辑:我按照教程中的说明设置 GCE 实例(即 Ubuntu 16.04 LTS，50GB 引导磁盘，1 个 GPU，带有 jupyter 和 tensorboard)

Answer 1

要解决第一个问题，看起来 nvidia-docker-plugin 已经在运行。要查找此服务，请使用:

sudo netstat -tlpn | grep 3476

并杀死它:

sudo pkill nvidia-docker

第二，安装 nvidia-docker2 并重新加载 Docker 守护进程配置:

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

# Install nvidia-docker2 and reload the Docker daemon configuration
sudo apt-get install -y nvidia-docker2
sudo pkill -SIGHUP dockerd
