if __name__ == '__main__':
    app=QApplication(sys.argv)
    ex=MainWindow()
    ex.show()
    sys.exit(app.exec_())

这是生成的加更改后的文件
更改的地方是

import sys
from PyQt5.QtWidgets import QApplication

class MainWindow(QtWidgets.QMainWindow):
    def __init__(self):
        QtWidgets.QMainWindow.__init__(self)
        self.setupUi(self)
        self.retranslateUi(self)

if __name__ == '__main__':
    app=QApplication(sys.argv)
    ex=MainWindow()
    ex.show()
    sys.exit(app.exec_())
