Getting Started as a Developer in Python 3 - Error

Hi,

I have followed these instructions: https://github.com/USEPA/SWMM-EPANET_User_Interface/wiki/Getting-Started-as-a-Developer-in-Python-3

What is the version of these packages? PyQt5 PyQt5-sip sip QScintilla

I have this error:

    import qgis.gui
  File "C:\OSGeo4W64\apps\qgis\python\qgis\gui\__init__.py", line 25, in <module>
    from qgis._gui import *
ValueError: PyCapsule_GetPointer called with incorrect name

Thanks
