This solved issues for me.

I mostly randomly enabled and disabled Attach to subprocess automatically while debugging and PyQt compatible until I found a version that was stable for me. Eventually it was stable at Attach to subprocess automatically while debugging enabled and PyQt compatible enabled at auto.

 - Second install matplotlib

I did change Pycharm from 2017.1.4 to Pycharm EAP 2017.2, but with no effect.

I solved the problem by making new python virtual environment and changing default Pycharm interpreter to it. Not the fastest solution I guess, but at least it worked.

Pycharm now again gives suggestions of building something for Cython, but now I just ignore it.
