first solution:
第一个解决方案：
import sys
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
ex = Ui_MainWindow()
w = QtWidgets.QMainWindow()
ex.setupUi(w)
w.show()
sys.exit(app.exec_())
Second Solution:
第二种解决方案：
class MainWindow(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent=parent)
ui = Ui_MainWindow()
ui.setupUi(self)
import sys
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
w = MainWindow()
w.show()
sys.exit(app.exec_())

self.setupUi(self)
import sys
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
