.exe file created with PyInstaller does not show its GUI

Question

I wrote a password generator and built a GUI for it using the PyQt5 designer. The script calls the .ui in its initiator and both are in the same folder.

def __init__(self, parent=None):
    super().__init__(parent)
    self.ui = uic.loadUi('Generator.ui', self)

However, after converting both to an .exe file via PyInstaller, after extracting the .exe file from its dist folder and executing it, a console pops up and closes immediately, without showing the GUI.

How can I fix this without manually adding the .ui code to the Generator.py script??

Thank you

I made this an answer show I could show an example. Use the pyuic tool to convert the .ui file to a .py file. The .py file this creates will have a class in it that is the name of the widget built in Qt Designer. Import and subclass this class into the GUI class that you are creating.

from designer_file import Ui_Gui  # Designer file is the converted .ui file and Ui_Gui is the ui class it created

class GUIWindow(QtWidgets.QWidget, Ui_Gui):

    def __init__(self):
        QtWidgets.QWidget.__init__(self)
        self.setupUi(self)  # This is necessary to setup the ui when using this method
        # Code here...
