I'm trying to make my Jupyter integration work with both stable and daily. Stable works fine, currently.
What the "kernel" does is to configure an IPyKernel application, using PyQt5 integration, and adding "/usr/lib/freecad/","/usr/lib/freecad/lib/" and "/usr/lib/freecad/Ext" to the Python path. Then I can import FreeCAD, FreeCADGui, shuffle the stdoutput streams a little, and optionally show the main window.
With FreeCAD stable I get some error messages about trying to import PySide2. However, the FreeCAD window appears to work normally, with all Workbenches...
With FreeCAD daily the Window is blank and does not seem to load any Addons or Workbenches. No error messages, though.
Any idea how to properly start FreeCAD daily from the system Python interpreter?
