Just start learning python tools making in Houdini. Knowing that houdini been using PySide2 with Python27 to create UI.And I have pip configured in my Houdini. It's possible to use the latest PySide6 to create UI without compatibility problems? :/
Houdini 20.0 is using QT5(5.15.2), which still uses Pyside2. On Windows, if you look in C:\Program Files\Side Effects Software\Houdini 20.0.724\bin you will find all the QT5 dlls.
