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):

Try installing PySide from pip first:
pip install PySide2
