有N卡但是nvidia-smi命令不显示信息出现NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA d

问题描述：使用nvidia-smi命令出现NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running

1 cd /usr/src/
2 
3 ls

然后查看nvidia-xxx，xxx为版本号，记下

1 sudo apt-get install dkms
2 
3 sudo dkms install -m nvidia -v xxx（你的nVidia版本号）

然后就可以用nvidia-smi命令查看信息啦

标签：because,显示信息,xxx,driver,版本号,smi,nvidia,NVIDIA
