I've recently installed Cuda and, as far as I'm aware, it is working correctly.

which nvcc returns

/usr/local/cuda-8.0/bin/nvcc

running tf.Session() returns

dpkg --get-selections | grep nvidia returns

enter image description here

nvidia-smi, however, returns

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. 
Make sure that the latest NVIDIA driver is installed and running.

and

lspci -v | grep "VGA controller" returns

00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 06) (prog-if 00 [VGA controller])

which seems to indicate that the nvidia isn't being used?

Could someone point me in the right direction to getting this sorted?

Thank you very much

EDIT: IMPORTANT

nvidia-settings reported that the NVIDIA driver is not loaded and that it could not find the registry key file

nvidia is known for being buggy with linix. you need the proprietary drivers. the most common nvidia drivers are available in the restricted/non-free repo. istalling the drivers should fix all the nvidia issues.

  • Will this not cause issue with my cuda installation? – tryingtolearn Jun 16 '17 at 16:38
  • I don't think so.the last line you posted shows that it is looking for the driver. >>>>tensorflow/stream_executor/cuda/cuda_diagnostics.cc:145] kernel driver does not appear to be running on this host: /proc/driver/nvidia/version does not exis – ravery Jun 16 '17 at 17:22
  • I found this, maybe it will help. https://askubuntu.com/a/134961/694267 – ravery Jun 16 '17 at 17:29
