I found that I can't see the ui in Maya when i load the ps_initial.mel in scripteditor and run the scripts.after run the function ps_initial() in mel.there was a lot of information about the format "# pyside2uic.uiparser : ................................... # ".
who can tell me why and help me to test the piSquare...
