DeprecationWarning: sipPyTypeDict() is deprecated PyQt5

Question

I was writing the most simplest piece of code to run some small app.

I got the next warning message:

~\PycharmProjects\LoggerTest\main.py:10: DeprecationWarning: sipPyTypeDict() is deprecated, the extension module should use sipPyTypeDictRef() instead
  class MainWindow(QMainWindow):

My code:

# Import libraries
import sys
# from PyQt5 import QtGui
# from PyQt5.QtCore import QEvent
from PyQt5.QtWidgets import QApplication, QMainWindow
# from PyQt5.QtCore import pyqtSignal #, pyqtSlot
from gui_ui import Ui_MainWindow


class MainWindow(QMainWindow):

    def __init__(self, parent=None, **kwargs):
        super(MainWindow, self).__init__(parent=parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)

        self.show()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    g = MainWindow()
    app.exec_()

What does that warning mean?

Answer 1

It is solved in python-3.12.0

After upgrading, the warning should be away.

If you don't want to upgrade your Python version, you can solve the problem by downgrading the PyQt5 module. For my Python 3.7.3 version, I fixed it by downloading PyQt5 version 5.15.4, PyQt5-Qt5 version 5.15.2, and PyQt5-sip version 12.12.1.
