Setup QtGui error

[diorn]

Hi, I keep running in this error when i try to run prism setup on Linux mint, Prism was working ok a few days ago but i did some system restore and can't get it back working because of this install error

Traceback (most recent call last): File "Scripts/PrismInstaller.py", line 66, in from PySide.QtGui import * ImportError: No module named QtGui Traceback (most recent call last): File "Scripts/PrismCore.py", line 69, in from PySide.QtGui import * ImportError: No module named QtGui

Try installing PySide from pip first: pip install PySide2
