To summarize: Plain python cannot pickle inner classes or functions: >>> class outer(object): ... class inner(object): ... pass >>> o = outer() >>> pickle.dumps(o) (works) >>> i = o.inner() >>> pickle.dumps(i) (ERROR)
The work-around is to make the cone factory a top-level class (or function), then it can be pickled just fine.
