unable to load nvidia nvml library

image-2021-04-28-10-45-28.pngHi, I've been using Arnold for a long time

A few days ago when I installed Maya 2022, when rendering, I encountered the error "unable to load nvidia nvml library"


I know the reason is that the graphics card driver is not updated

But the problem is that I just updated it yesterday.

You can also see the version of my driver in the picture

This looks like it could be a problematic driver install. Arnold expects the nvml executable to be in the windows driver store or %WINDOWS%/system32 folder, as per nvidia's recommendation. I've heard of a problem where the nvml tool will sometimes be installed elsewhere on windows 8.1 machines.

Running "where nvml.dll" in the console might give you some clues as to what's going on.

What should I do?c249.jpg

I would reinstall the graphic card driver, because that is what puts nvml.dll on your system. There should be several copies.

I did, but to no avail

I think installing the previous version of Maya and Arnold will solve the problem

Installing Maya, MtoA, or Arnold won't install nvml.dll

Is that dll still missing from the system?
