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.

tv ("#textview") is a small tool to quickly view high-resolution multi-band imagery directly in your terminal. It was designed for working with (very large) #satellite imagery data over a low-bandwidth connection. For example, you can directly visualise a Himawari 8 (11K x 11K pixel) image of the Earth directly from its URL:
It is built upon the wonderful #GDAL library so it is able to load a large variety of image formats (GeoTiff, PNG, Jpeg, NetCDF, ...) and subsample the image as it reads from disk so it can handle very large files quickly. It has the ability to read filenames (or URLs) from stdin and load files directly from URLs without writing locally to disk. Command line options are styled after gdal_translate such as:
-b to specify the bands (and ordering) to use,
-srcwin xoff yoff xsize ysize to view a subset of the image,
-r to specify the subsampling algorithm (nearest, bilinear, cubic, cubicspline, lanczos, average, mode).
