PyQt5: The specified module could not be found I try to start learning PyQt5 in blender but i've got this error when i try to import a module.

ImportError: DLL load failed: The specified module could not be found


This is my import line:

import sys

sys.path.append('C:\\Users\\pistiwique\\AppData\\Local\\Programs\\Python\\Python35\\Lib\\site-packages')

from PyQt5 import QtGui


If i test these lines whith PyCharm, there is no probleme so it seems to come from Blender but why ?
I remember that i ran into this error too. I think the problem was the qwindow.dll. 

For me the necessary steps were: install the correct PyQt5 version directly into the python directory of the binary. For 2.76 the PyQt folder has to be in the 2.76\python\lib\site-packages directory.Then you need to grab the qwindow.dll, put it into a folder called platforms, and put it asides the Blender exe. And you should be ready to go.
