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 US government has revealed a list of items Americans should keep on hand in case of an emergency.
Officials warned that households should be prepared to survive on their own for several days if disaster strikes, with no immediate access to outside help.
The Department of Homeland Security recommends storing enough water, food, and medical supplies to sustain every person in a household during an extended emergency.
At the top of the list is water, at least one gallon per person per day, along with several days' worth of non-perishable food. Americans are also urged to keep critical safety items such as flashlights, radios, batteries, and first-aid kits readily available in a portable emergency supply kit.
Officials said the supplies should be stored in airtight containers and kept in easy-to-carry bins or bags in case families need to evacuate quickly.
The checklist also includes tools to signal for help, sanitation supplies, and equipment to shelter safely indoors if conditions outside become dangerous.
While the Trump administration has not urged Americans to stockpile large quantities of supplies, federal officials and preparedness experts recommend keeping essential items on hand in case of an emergency.
