GPU cards not detected

Graphics / Linux Linux

Hi there,

I have 4 GPU cards (GTX 1080Ti) installed on my Linux workstation (CentOS 7). I can see them when I run lspci.
#lspci | grep -i nvidia
05:00.0 VGA compatible controller: NVIDIA Corporation Device 1b06 (rev a1)
05:00.1 Audio device: NVIDIA Corporation Device 10ef (rev a1)
06:00.0 VGA compatible controller: NVIDIA Corporation Device 1b06 (rev a1)
06:00.1 Audio device: NVIDIA Corporation Device 10ef (rev a1)
09:00.0 VGA compatible controller: NVIDIA Corporation Device 1b06 (rev a1)
09:00.1 Audio device: NVIDIA Corporation Device 10ef (rev a1)
0a:00.0 VGA compatible controller: NVIDIA Corporation Device 1b06 (rev a1)
0a:00.1 Audio device: NVIDIA Corporation Device 10ef (rev a1)

However, after I installed the CUDA-8.0 driver and toolkits, I did not see the names when I ran “nvidia-smi”

Instead of showing GTX 1080Ti, it shows ERR!.

Could you help me figure out what the problem is? Thanks! Please let me know if additional information is needed.

Thanks,
Alex

Did you install the nvidia driver at all, just cuda is not enough? if so, which version? Run nvidia-bug-report.sh and attach output file to your post then.

Yes, the version I used was 375.26 in yum repository. I just updated it to 375.66 from nvidia’s website. Now it works. Thanks!
