I used qt designer to design my user interface. From kled widgets (I think it’s kde extension probably called kf5) and some other things.
Now, when I converted the .ui file to .py for use, Python cannot execute these lines:

from KTextBrowser import KTextBrowser from ktextedit import KTextEdit from KLed import KLed

I installed the kde5py package in Python, as well as kf5, but I did not get any results
