nvidia-docker：未知的运行时指定了nvidia

问题描述

我在安装docker-ce之后尝试安装nvidia-docker。我遵循以下步骤：安装nvidia-码头工人它似乎已正确安装。

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.

我尝试运行：

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

尽管如此，这可行（没有--runtime = nvidia）：

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

$ docker container run -ti ubuntu bash

我的系统上的一些其他信息：这是一个ubuntu服务器16.04，带有8个GPU（Titan Xp）和nvidia驱动程序版本387.26。我可以在主机系统上运行nvidia-smi -l 1，它可以按预期工作。

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)'

            "runtimeArgs": []
        }
    }
}

我遇到过：，但我不确定该怎么做。

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

推荐答案

实际上，您可以尝试通过以下命令重新启动docker daemon。

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

sudo systemctl daemon-reload
sudo systemctl restart docker

或者您可以尝试重新启动系统。
使nvidia-docker工作

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