I am trying to have a bootable USB stick that starts a python app with a Qt interface. I get an error on loading QtCore :

# code object from 'X:\\Python313\\Lib\\__pycache__\\string.cpython-313.pyc'
import '_string' # <class '_frozen_importlib.BuiltinImporter'>

Traceback (most recent call last):

ImportError: DLL load failed while importing QtCore: The specified procedure could not be found.

I use WinPE v 10.0.14393.0

Any idea what could be the issue ?

Best,

  • Python wasn't created to make .exe and programs like PyInstaller sometimes have problem to find all needed Python modules and C/C++ libraries (.dll). It may need to manually add missing file to config file .spec before running PyInstaller. Using Spec Files — PyInstaller 6.16.0 documentation, When Things Go Wrong — PyInstaller 6.16.0 documentation Commented Sep 18 at 19:55
  • Thanks, but I have the same issue when I do not use PyInstaller and I run the script with python.exe. So there is another problem. Commented Sep 19 at 12:23
  • if you have the same problem before using pyinstaller then maybe remove information about pyinstaller because pyinstaller can be missleading in this problem. Commented Sep 19 at 13:18
  • Was pretty clear but I did it anyway. Thanks Commented Sep 19 at 14:47
  • I'm not familiar with QT, but is your issue similar to that one? stackoverflow.com/questions/65746847/… Commented Sep 22 at 5:32
