Runtime Error When Calling A .exe Made With Pyinstaller Including Pyqt4

So, I have two .py files, one generated by QtDesigner and another which basically implements the functionality of the GUI. Using, pyinstaller, I generated a .exe file to use it on

Solution 1:

So, I finally made it to work. Not the ideal case, where I don't have to change the library to PyQt5 and make sure everything is in order with PyInstaller, but it works. So here is what I did:

1. Installed Python version 3.5 - This was because after I updated to the latest PyInstaller version (3.4) and tried to run on python 3.4, I was getting a new error where it was not able to find Qt plugins. After some searching, I figured that since I installed PyQt5 on Python version (3.4) using a .whl file I found on Python Extension Packages for Windows, the installation didn't come bundled with sip. Additionally, when I tried to install PyQt5 on Python 3.4 using pip, it wouldn't install.

2. Installed PyQt5 and all other libraries on the new Python version using pip. Note: This version of python doesn't have a PyQt4 installed, so it is quite possible that this was the reason. I will install PyQt4 on this python version and try making the .exe again using PyInstaller and see what happens.

So, to summarize, PyQt5 + Pyinstaller works only for Python version >= 3.5. Hope it helps others!
