PyQt5 No Error But GUI Window Not Loading

[digitalmatic7]

Hey guys any ideas whats up with this?



It's not using QtGui in the code yet its been imported (see above pic) - could that be causing the problem?

Code below:

Hide/Show

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'myfirstbutton.ui'
#
# Created by: PyQt5 UI code generator 5.9
#
# WARNING! All changes made in this file will be lost!

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(671, 309)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.myfirstButton = QtWidgets.QPushButton(self.centralwidget)
        self.myfirstButton.setGeometry(QtCore.QRect(240, 90, 181, 81))
        self.myfirstButton.setObjectName("myfirstButton")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 671, 21))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.myfirstButton.setText(_translate("MainWindow", "My Button"))

Am I supposed to call one of those defines or the class or something? I was watching some tutorials and they just run the code and the window pops up. Not sure why its not working for me lol.

UPDATE:
-------
Got it working by uninstalling an old version of Python (2.7) guess there was some kinda conflict.

Could also be that I wasn't using -x

pyuic5.exe -x myfirstbutton.ui -o myfirstbutton.py
