PyQT5 legacy version support

[Kyle Altendorf]

Wheels were only published ever for Python 3 as I recall.  And source
distributions were only available on PyPI since 5.14 I think.  You can
get development snapshots on the Riverbanks site, but that's only latest
and only development. 

https://riverbankcomputing.com/software/pyqt/download5 

But...  you can get old stuff from sourceforge it seems. 

https://sourceforge.net/projects/pyqt/files/PyQt5/PyQt-5.5.1/ 

So basically, you can do something but you are asking for trouble when
you have old compiled libraries that you can't rebuild... :|  (referring
to your own .so) 

Best of luck. 

Cheers,

However, that is a very difficult option, as part of the application imports a .so module, which is C++ code compiled and wrapped for use in a python application. This application was built with python2 libraries and will not import if the application is built with Python3.
