I've installed the Project Pegasus Demo hda's/otls supplied with the Project Demo Files as a package & now whenever I open Houdini (20.0.625) I get this console message;

opdef:/Sop/PE_heightfield_paths::2.0?ViewerStateInstall (1): Unknown command: __import__

Anyone know how to fix this apart from uninstalling the hda?

I fixed it by installed it into a hda folder inside my Houdini Project folder instead of loading it from the package folder.

It seems `PE_heightfield_paths::2.0` has an error; it has an empty SOP inside named Pe Rolldown Heightfield, and I beleive this is causing both the warning on startup and the Postprocessing options not working..
