You need to create a class that inherits from QMainWindow and your form, you also need to call setupUi. Next, run as a normal PyQt application:

import sys

from PyQt5.QtWidgets import QMainWindow, QApplication
from Ui_Form import Ui_Form  # Замените на импорт вашего класса


class MainWindow(QMainWindow, Ui_Form):
    def __init__(self):
        super().__init__()
        self.setupUi()


app = QApplication(sys.argv)
main_window = MainWindow()

main_window.show()
sys.exit(app.exec_())
