NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running

问题描述

之前好好的,一段时间之后,在调用 nvidia-smi 的时候出现一下错误,大无语事件

详细状况:

$nvidia-smi

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

出错描述:在运行 nvidia-smi 查看显卡信息的时候报错 NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running

出错原因:Nvidia 驱动出了问题

问题处理

**(1)首先查看显卡驱动的型号 **

第一种:官网查询

如果知道自己的显卡信息,输入自己的显卡信息,然后查询对应的型号

NVIDIA-SMI has failed because it couldn‘t communicate with the NVIDIA driver. Make sure that the lat

例如 我这里查看我的型号支持为 470.94 需要记下来,到时候后面安装版本会用到

NVIDIA-SMI has failed because it couldn‘t communicate with the NVIDIA driver. Make sure that the lat

第二种:直接服务器上查询

ubuntu-drivers devices

可以看到,这边有多个,推荐的是安装495,其实这几种都可以

(2)看显卡驱动版本支持的cuda 官网查看

如果不想去官网,这里附上一个截屏下来的参考图

NVIDIA-SMI has failed because it couldn‘t communicate with the NVIDIA driver. Make sure that the lat

需要服务器安装符合要求的 CUDA 版本,CUDA安装与切换

(3)卸载与安装驱动

卸载驱动:

sudo apt-get autoremove --purge nvidia-*

# 卸载完之后在重新安装驱动,可以重新安装一下linux
sudo apt-get install --reinstall linux-headers-$(uname -r)

安装驱动:

# 安装驱动源
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
# 第一种:#直接安装推荐的驱动
sudo ubuntu-drivers autoinstall 
# 第一种:#直接指定版本的驱动
sudo apt-get install nvidia-384 

然后重启 再执行nvidia-smi 命令即可

文章传送门:

CUDA安装与切换

显卡驱动查看 官网查询

CUDA版本官网查看

gcc、g++安装、版本降级、升级
