Import error in init.py and client.py

[Crims-on]

init.py error:
from PyQt5.QtGui import QPalette, QColor
ImportError: No module named PyQt5.QtGui

client.py error:
from PyQt5 import QtWidgets
ImportError: No module named PyQt5

I have installed PyQt5 and uninstalled it multiple times using different methods. I have tried installing pytq which was a possible solution in a previous issue thread, but apparently, there is no such distribution
