Re: [Modeling-users] problems with inheritance

[<seb...@nu...>]

  I think that the pb. here is that the root package, named
after the model's package nale (here: 'Person' AFAIK) isn't
in the python path.

  Could you check whether you get the same error with
/home/lgs/proyectos/pruebas-modeling/
in your PYTHONPATH (before '.', in case you have in the py-path),
and report back?  Thanks.

(I can't check it here right now, despite the fact that you
 send us the whole code, sorry).
