    Okay, I used pyuic5 -x window.ui -o window.py in the same directory as my window.py, but it gives me

    Fatal error in launcher: Unable to create process using '"d:\python\python.exe"  "D:\Python\Scripts\pyuic5.exe" -x window.ui -o window.py': The system cannot find the file specified.
    

    I'm not sure why it can't find the file. It doesn't work if I provide a direct file path either.

    I don't know. But have a Google for, say, pyuic5 Fatal error in launcher. I'm getting a few hits for you to look through. I think one possible suggestion was make sure everything is either 32- or 64-bit?

    I think the pyuic on your PATH is a pyuic.bat, which runs python.exe to execute the pyuic5.exe. Try just running D:\Python\Scripts\pyuic5.exe directly and see whether you get an error from that?

      I can only find an instance of pyuic5.bat in an anaconda folder, which I do not use. I was originally running pyuic5.exe, which returns the error I'm getting. Sorry for not elaborating better. As for 32-bit vs. 64-bit, I have verified everything is 64-bit.

        How did you install PySide2 exactly ?

          With pip install pyside6 (I use PySide6 but I was told they were the same but with more features so I'm not sure it matters)

            PySide6 is not the same as PySide2, hence the 6 instead of 2! It's PySide for Qt6, instead of for Qt5. It's new. It does not yet have all features either.

            And I notice you are running pyuic5, which I assume from the 5 is for Qt5.

            Anyway, if it were me, I would scrub (uninstall, remove) anything Qt6/PySide6, and install Qt 5.15-ish (latest) + PySide2. (If the PySide2 comes with its own version of Qt5 [I don't know if that's how it works] that's fine, you don't need to do Qt5 separately.) And try again, at least to see how that fares in comparison.

              Is it your system pip ? Conda ?

                @JonB I have uninstalled PySide6 and installed PySide2 and I get the same error.
                @SGaist I don't think it is but I'm not sure how to tell

                I attempted to use a mix of PySide6's normal features with PyQt5's uic module, but using

                class TexasHoldEmServerWindow(QMainWindow):
                    def __init__(self):
                        super(TexasHoldEmServerWindow, self).__init__()
                        uic.loadUi(os.path.join(os.path.dirname(__file__), "window.ui"), self)
                

                Raises this error:

                Exception has occurred: TypeError
                ('Wrong base class of toplevel widget', (<class 'topaz.server.texas_hold_em.server_window.TexasHoldEmServerWindow'>, 'QMainWindow'))

                  Isn't the original base widget a QWidget ?

                      Then what base class did you select in designer ?

                        The main window is QMainWindow but I have a layout inside the window (grid) which is QWidget. Inheriting either gives the same error however.

                          I was able to get it working by using pyuic6 window.ui -o window.py
                          I have this:

                                  super(TexasHoldEmServerWindow, self).__init__()
                                  self.window = Ui_MainWindow
                                  self.window.setupUi(self)
                          

                          But setupUi() also needs to passed a parameter called MainWindow, but I'm not sure what to give it here.

                            I got it sort of working using a bit of code someone put in a stack overflow post:

                            from PySide6.QtCore import QMetaObject
                            from PySide6.QtUiTools import QUiLoader
                            
                            class UiLoader(QUiLoader):
                                def __init__(self, baseinstance, customWidgets=None):
                                    QUiLoader.__init__(self, baseinstance)
                                    self.baseinstance = baseinstance
                                    self.customWidgets = customWidgets
                            
                                def createWidget(self, class_name, parent=None, name=''):
                                    if parent is None and self.baseinstance:
                                        return self.baseinstance
                                    else:
                                        if class_name in self.availableWidgets():
                                            widget = QUiLoader.createWidget(self, class_name, parent, name)
                                        else:
                                            try:
                                                widget = self.customWidgets[class_name](parent)
                                            except (TypeError, KeyError) as e:
                                                #raise Exception('No custom widget ' + class_name + ' found in customWidgets param of UiLoader __init__.')
                                                pass
                                        if self.baseinstance:
                                            setattr(self.baseinstance, name, widget)
                                        return widget
                            
                            def loadUi(uifile, baseinstance=None, customWidgets=None,
                                       workingDirectory=None):
                            
                                loader = UiLoader(baseinstance, customWidgets)
                            
                                if workingDirectory is not None:
                                    loader.setWorkingDirectory(workingDirectory)
                            
                                widget = loader.load(uifile)
                                QMetaObject.connectSlotsByName(widget)
                                return widget
                            

                            Then I add this to my UI Class:

                                    QMainWindow.__init__(self)
                                    loadUi(os.path.join(os.path.dirname(__file__), "window.ui"), self)
                            

                            But it keeps saying the widget creation fails.

                                AFAIK, you can't close the thread however you can either delete your post or post a link to the new thread.
