DeprecationWarning：sipPyTypeDict（） 已弃用 PyQt5

问：

我正在编写最简单的代码来运行一些小应用程序。

我收到了下一条警告消息：

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

我的代码：

# 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_()

该警告是什么意思？
