So pickle complains about the class PeriodicGrid not being found in the
module hyper, but a dir()
proves that python can find it. Has anyone an idea what's going wrong
here?
These symptomps are pretty weird -- let's try to pin things down a bit more. The relevant few lines of pickle.py are:
try: __import__(module) mod = sys.modules[module] klass = getattr(mod, name) except (ImportError, KeyError, AttributeError): raise PicklingError(
so, could you please edit your pickle.py to provide VASTLY more info,

and let us know exactly what his modified pickle.py outputs...?
Here it goes...:
OOPS, error (exceptions.ImportError): No module named hyper

I have noticed that the error does not occur, when the imported module ('hyper') is in the same directory as the script that pickles. When it is imported from a subpackage (like in the code
I sent you) it goes wrong.
