clinfo shows "Number of platforms 0"

Question

I'm developing on Centos 7.6 64bit and Nvidia graphic card. I've installed Nvidia driver and cuda driver.

But, when I run "clinfo", it shows:

Number of platforms                               0

What should I check and how can I solve it?

Answer 1

The cuda's nvidia driver and your display nvidia-driver should match. I faced this problem yesterday and solved it but installing nvidia-driver suggested in cuda run file. make sure that /var/lib/dkms/nvidia/<version> links properly with kernels. see my topic for more info.
