Yesterday, @jschueller added pyside2-feedstock to conda-forge. This means we can now finally install PySide2 easily in Python 2.7, 3.5 and 3.6 on Windows, Linux and macOS using conda.

An alternative to building PySide2 from source

I’ve received questions lately on the issues that people are having while attempting to build PySide2 on Windows, macOS and Linux. Instead of building PySide2, there’s actually a workaround which works just as well for some people…

Dealing with Maya 2017 and PySide2

Mon, 25 Jul 2016 00:00:00 +0000

Maya 2017 was released today and with it comes a big change; PySide (and PyQt4) no longer works with Maya.

This guide explains how to deal with that and make your Python and PySide/PyQt scripts compatible with Maya 2017 as well as older Maya versions.

This guide is also applicable to e.g. Nuke or any other Python-enabled DCC app which uses Qt.

Background (Qt4 vs Qt5)

Starting with Maya 2011, Maya’s user interface is built using the Qt toolkit. Up until and including Maya 2016, Qt of version 4 (“Qt4”) which was released in 2005 has been used. Today, roughly 11 years after the Qt4 release, and starting with Maya 2017, Qt was upgraded to version 5 (“Qt5”) to enable a host of enhancements to Maya. Unfortunately, this also breaks backwards compatibility to Qt4.
