NVIDIA-SMI has failed because it couldn‘t communicate with the NVIDIA driver.

(base) jzzz@jzzz-System-Product-Name:~$ 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.

第一步，使用nvcc -V检查驱动和cuda。
如图发现驱动是存在的，于是进行下一步

第二步，查看已安装驱动的版本信息
ls /usr/src | grep nvidia

比如我的驱动版本是：nvidia-580.82.07

第三步，依次输入以下命令
sudo apt-get install dkms
 
sudo dkms install -m nvidia -v nvidia-580.82.07

出现报错
Error! Your kernel headers for kernel 6.14.0-29-generic cannot be found at /lib/modules/6.14.0-29-generic/build or /lib/modules/6.14.0-29-generic/source. Please install the linux-headers-6.14.0-29-generic package or use the --kernelsourcedir option to tell DKMS where it's located.

找到解决办法如下：

 

sudo apt install linux-headers-6.14.0-29-generic

实际上我运行完，安装好后这个后，再次nvidia-smi已经成功
