I just pip installed PySide under the unreal engine installed python.


C:\Program Files\Epic Games\UE_4.21\Engine\Source\ThirdParty\Python\Win64>python -m pip install --upgrade pip
C:\Program Files\Epic Games\UE_4.21\Engine\Source\ThirdParty\Python\Win64>python -m pip install PySide

Thanks, that did the trick. I had not realised that UE was using its own Python installation instead of the one from the OS, which makes complete sense now that I think about it.
