Nvidia-smi says:no devices were found

I just fixed the problem that the kernel modules and the libraries have different versions by seeing the topic : failed-to-initialize-nvml-driver-library-version-mismatch/190421
then I reboot and get this problem
nvidia-bug-report.log.gz (404.3 KB)

Please also check for a bios update.

kern.log (1.4 MB)
yes, I also met ’ RmInitAdapter failed! (0x26:0x56:1429)', but I am not clear what I should do to fix it because I am a beginner, could you give me some advice?should I reduce kernel version and libraries version both? thank for your patience!

Please unistall the packaged nvidia driver first, then use the runfile driver of mentioned driver version from here:
run it with --dkms option.

Which version should I use?

and is it ok to use ‘sudo apt purge nvidia* libnvidia*’ to uninstall the driver? I am not sure about that…

I need guidance very urgently, could you give me a replay? thank you very much

You could use Software&Updates to switch to nouveau driver, this should remove the nvidia packages. Or run
sudo apt remove nvidia*
sudo apt autoremove

I fix it! thank you again!
