undefined symbol: cuDevicePrimaryCtxGetState when importing tensorflow - python-2.7

Question

everyone!
I'm trying to install and run tensorflow (GPU-support). I followed the guide and installed cudnn 7 and cuda 9.0.
However, when trying to import tensorflow, I get the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

How can I fix it?

I had the same problem - I had already installed the required NVIDIA drivers on my Ubuntu machine, but when I tried to import Tensorflow I got the same error.
So for me the problem was that I was using the Nouveau driver instead of the NVIDIA driver. In order to fix the issue you need to go to System Settings->Software & Updates->Additional Drivers and select the option Using NVIDIA binary driver ... and then click at the Apply Changes button. Then just reboot and you're done.
