At a guess I'd say that the Sverchok folks have updated their API and self.idtree or self.idname no longer does what it once did :)

Hi topologic, just followed your 'Topologic Sverchok: Finding Adjacent Cells in a CellComplex' Youtube video. It works as demonstrated on Windows 10 without the "cppyy" errors I was

Also if you are on Windows a much improved version is available from the same location on https://topologic.app. Topologic Sverchok has the following optional python libraries dependencies:

The second tutorial from the series "Classical Rhino-Grasshopper algorithms translated into Blender-Sverchok" is ready.

I think OsArch and others with YouTube courses could offer Certificates in Cursa or individually to impulse open-source popularity, specially Blender, FreeCAD, BlenderBim, Sverchok, Inkscape, etc, and
