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.

🌎 The mysterious "terror bird" Titanis walleri once roamed North America about 2 million years ago. Standing nearly 2.5 meters tall, it was a flightless predator with a massive hooked beak. Fossils show it preyed on small mammals, and its closest living relatives are modern seriemas of South America. ✨

🌎 Ice Age cave lions once roamed across Europe and Asia, hunting mammoths and bison in frigid steppe. Larger than today’s lions, these extinct predators are known from beautifully preserved cave paintings and even mummified cubs found in Siberian permafrost. ✨

🌎 The chambered nautilus, often called a “living fossil,” has survived nearly unchanged for over 500 million years. Its spiral shell and tentacled, squid-like body resemble fossils from the early Paleozoic era. Living nautiluses inhabit deep reefs in the Indo-Pacific and can have over 90 tentacles. ✨

🌎 The Gomphothere, an ancient cousin of elephants, once roamed the Americas with shovel-shaped lower jaws. These extinct giants sported four tusks instead of two, thriving for millions of years before vanishing at the end of the last Ice Age. ✨

🌎 Long before trees, Earth was covered in giant mushrooms called Prototaxites, some reaching up to 8 meters tall. These towering fungi dominated ancient landscapes 420 million years ago, before forests appeared. ✨

🌎 The pikaia, a tiny worm-like creature from 500 million years ago, may be one of our earliest known ancestors. Its flexible, cord-like structure helped pave the way for the backbone found in all vertebrates today. ✨

🌎 Australian megafauna like Diprotodon, the largest marsupial ever, disappeared about 46,000 years ago. These giant wombat relatives weighed up to 2,750 kilograms. The cause of their extinction is debated—some studies suggest climate shifts, while others blame human hunting. Diprotodon fossils have been found at over 100 sites across Australia. ✨

🌎 The mysterious extinction of the “Siberian unicorn,” or Elasmotherium sibiricum, puzzles paleontologists. This massive Ice Age mammal, related to modern rhinos, had a large forehead horn and grazed Eurasian steppes. DNA studies show it survived until about 39,000 years ago—much later than once thought. ✨

🌎 The woolly rhinoceros, Coelodonta antiquitatis, roamed Ice Age Eurasia with a thick fur coat and massive horn. Fossils found in Siberian permafrost show it survived extreme cold; its extinction about 14,000 years ago is linked to climate warming and human hunting. ✨

🌎 The giant short-faced bear, Arctodus simus, roamed North America during the last Ice Age. Standing up to 1.5 meters at the shoulder, it was one of the largest terrestrial mammalian carnivores ever, yet paleontologists debate if it was mainly a predator or a scavenger. Fossils suggest it vanished around 11,000 years ago, along with much other megafauna. ✨

🌎 The Siberian unicorn, or Elasmotherium, was a massive prehistoric rhinoceros with a single huge horn on its forehead. Fossils show it roamed Eurasia until about 39,000 years ago, much later than once believed. ✨
