centos7 安装 NVIDIA Docker

akyou56

　　安装环境：
　　1、centos7.3
　　2、NVIDIA Corporation GP106 [GeForce GTX 1060 6GB]
　　安装nvidia-docker
　　a、安装docker 可参考centos7 安装docker
　　b：



# Install nvidia-docker and nvidia-docker-plugin
wget -P /tmp https://github.com/NVIDIA/nvidia-docker/releases/download/v1.0.1/nvidia-docker-1.0.1-1.x86_64.rpm
sudo rpm -i /tmp/nvidia-docker*.rpm && rm /tmp/nvidia-docker*.rpm
sudo systemctl start nvidia-docker
# Test nvidia-smi
nvidia-docker run --rm nvidia/cuda nvidia-smi
　　如果出现异常：



[iyunv@localhost ~]# nvidia-docker run --rm nvidia/cuda nvidia-smi
/usr/bin/docker-current: Error response from daemon: create nvidia_driver_384.69: create nvidia_driver_384.69: Error looking up volume plugin nvidia-docker: plugin not found.
See '/usr/bin/docker-current run --help'.
　　则检查nvidia-docker是否启动：



[iyunv@localhost ~]# systemctl status nvidia-docker

　　如果出现以下情况：



[iyunv@localhost ~]# nvidia-docker run --rm nvidia/cuda nvidia-smi
NVIDIA-SMI couldn't find libnvidia-ml.so library in your system. Please make sure that the NVIDIA Display Driver is properly installed and present in your system.
Please also try adding directory that contains libnvidia-ml.so to your system PATH.key
　　可以尝试一下加参数--privileged=true ，如果没问题，则需要修改selinux配置,编辑/etc/selinux/config：



SELINUX=disabled
SELINUXTYPE=targeted

或者尝试selinux模式为permissive模式 setenforce 0
　　重启机器，重启服务器即可。
