Solving GPU Problems¶

After updating drivers or software in Ubuntu, an NVML error occurs: Driver/library version mismatch¶

If you encounter an error like Failed to initialize NVML: Driver/library version mismatch after installation, it is necessary to reconnect the Nvidia kernel modules by deleting them and running nvidia-smi again for reinitialization:

sudo rmmod -f nvidia-modeset
sudo rmmod nvidia_uvm
sudo rmmod nvidia_drm
sudo rmmod nvidia-peermem
sudo rmmod nvidia
sudo nvidia-smi

The error can also occur due to the /boot partition being full during simultaneous system kernel updates and an inability to build new initial RAM disks (initrd) with video card modules. To fix this, use this instruction.

If the error persists, it is recommended to remove Nvidia driver packages

sudo apt purge -s "nvidia*" "libnvidia*"
sudo apt autoremove
sudo apt --fix-broken install

and reinstall them (and CUDA) anew.
