Failed to initialize NVML: Driver/library version mismatch

The client version is higher than version of kernel module

Hi there @nb4 and welcome to the NVIDIA developer forums.

I am not sure what you are asking, you have mismatching driver versions in your Linux installation. The client, that is the NVML installed apps, has an older version than the installed kernel module.

So the simplest solution is to update your client, the NVML apps and likely the driver package, to the same version as the kernel module. Or alternatively just remove the current NVIDIA driver completely and install it from scratch based on the latest recommended version for your system.
