由于未知原因, 显卡驱动丢失, 采用 nvidia-smi
命令查看, 错误提示如下:
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver.
Make sure that the latest NVIDIA driver is installed and running.
解决方案一:
参考: 无法连接NVIDIA驱动:NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver
#查看已安装驱动版本号
ls /usr/src | grep nvidia
#如:nvidia--460.32.03
sudo apt install dkms
sudo dkms install -m nvidia -v -460.32.03
解决方案二:
重新安装驱动, 并重启.
sudo apt install nvidia-driver-460
sudo reboot
