NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
sudo dkms status
nvidia, 460.39, 5.8.0-40-generic, x86_64: installed
I’ve tried uninstalling and reinstalling the driver several times.
My system specs are -
Processor - AMD Ryzen 5 3550H
RAM - 8 GB
