The solution was to install PyQt5 /EnvironmentDirectoryPath/pip3 install PyQt5 .

Found details at https://www.riverbankcomputing.com/static/Docs/PyQt5/installation.html#understanding-the-correct-version-to-install

I also installed it system wide with sudo apt-get install python-qt4 with no ill effects.
