I have some Designer .ui-files that have nothing that needs translation. Currently when I do:

uic -g python untitled.ui -o untitled_ui.py

I get code like
    def retranslateUi(self, Form):
    # retranslateUi
when trying to import one gets:

Traceback (most recent call last):
{{ File "<stdin>", line 1, in <module>}}
{{ File "C:\Python38\lib\site-packages\PySide2\untitled_ui.py", line 37}}

^
SyntaxError: unexpected EOF while parsing

suggested result

There could be multiple ways this could be solved:

1. like pyside2uic used to just add a pass to these empty functions. So the code would look like:

    def retranslateUi(self, Form):
{{        pass
    # retranslateUi}}

1. Empty functions and calls to them could be removed alltogether!

I personally would suggest the latter.
