В прошлом посте говоря "Все вызовы теперь одинаковы" я несколько слукавил. Всё-таки есть в этом зоопарке версий некоторая несовместимость вызов которой просто так не унифицировать. Эти моменты вынесены в отдельный модуль QtCompat (compatibility). Там не так много функций но они довольно полезны.
Этот модуль содержит унификаци модуля shiboken2, функций loadUi, translate и несколько переименованных функций классов или изменённую сигнатуру аргументов и возвращаемых значений. Это единственное исключение из правила когда вам потребуется где-то изменить свой код кроме импортов и этот код не похож на обычный код PySide2.
Например, в PyQt4 и PySide есть метод
QHeaderView.setResizeMode
Для PyQt5 и PySide2 они были благополучно переименованы в
QHeaderView.setSectionResizeMode
Чтобы применить этот метод следует использовать такой код
from Qt import QtCompath
header = self.horizontalHeader()
QtCompat.QHeaderView.setSectionResizeMode(header, QtWidgets.QHeaderView.Fixed)
Унификация загрузки UI файлов:
# PySide2
from PySide2.QtUiTools import QUiLoader
loader = QUiLoader()
widget = loader.load(ui_file)
# PyQt5
from PyQt5 import uic
widget = uic.loadUi(ui_file)
# Qt.py
from Qt import QtCompat
widget = QtCompat.loadUi(ui_file)
Хорошо что таких моментов не много и их легко запомнить.
Полный список можно посмотреть в таблице.

More thoughts on spinning.
I hope you'll indulge me with this detour/personal journey of mine.
Processing and spinning wool seems an unnecessary and tedious task when there is everything else to worry about. However, some animals, like sheep, can be dual purpose. Why not learn to utilize what else they have to offer?
For some of us, the fiber is so worthwhile that we'd keep animals just for that purpose alone! (Hence my alpaca obsession - plus they are cheap therapy!)
The reason why I'm starting to love spinning is because it is a mindful, yet mindless task that you can simply pick up and tend to without thought. Just feeling, stretching, twirling.
With knitting, you must actively think. Processing and spinning fiber is a perfect complement to the art, a duty to put thoughts to rest and focus only on how the fiber feels.
It's not about getting it done quickly, it's not about profit. It's about enjoying your time and feeling empowered in what you're able to create with your own hands.

Elaborating on the Removal of Vegetable Matter (specifically when there's a lot of it)
And thoughts on your environment's impact on how dirty your fleece gets

How things are going.
This is a Golding top whorl drop spindle. They kindly sent me some kind of hideous fiber to experiment with, which I gladly did, although I found it awful to work with. Probably not the best intro to spinning.
I skirted and clouded a small portion of Obsidian's fleece to see how it does in comparison. My hand carders are still sitting in my PO box, so I still have to wait for that - it makes the fluffing easier. No wash, just taking bits of vegetable matter out, and I gotta tell ya, it is really messy. Fluffing and picking seemed to get a lot of dust out, so spinning isn't that dirty, actually. It may even be giving it more grip.
It is far easier to spin that I expected. People say alpaca is not a good wool to start with because it's too slippery, but I found it extremely easy to draft and spin evenly. It may have something to do with the generous 3" of staple length.
I will try to record a short video of the skirting process tomorrow.
Still new, but learning.

Thus begins the processing of raw alpaca wool for the first time - just so you know what my time is occupied by.
Once I master this, I will be happy to share the process.
I am learning to spin as well, and hopefully will produce a skein in not too much time.
This comes from our alpaca Obsidian, a gentle fellow who's very intelligent and sensitive.
