When running clinfo and opencl programs, both prompt that no platform can be found.

Describe the bug

When I try to type clinfo, it shows

Number of platforms 0

Then I type "dmesg | grep NVRM", it reports error. So I started to think it might be a version mismatch issue.

But when I checked the driver and kernel versions, I didn't find any mismatch. What is the cause of this or do I need to provide more information?

You have some part of 570.86.15 installed. Mine shows platforms 0 because drivers do not match and I can't install cuda runtime properly. Yet another reason why taking random driver versions by themselves and patching them is shitty.

[Ph0rk0z]

ok.. so missing file is under /etc/OpenCL/vendors

you gotta make an nvidia.icd with libnvidia-opencl.so.1

Also need the mesa ICD loader package that creates the folder and allows clinfo to run. This file is in the arch package but for ubuntu MIA. Was hard to track down but now my openCL is working, even with the mismatched driver.
