Hey @gusseppe,

What is the exact error u see?

[gusseppe]

Apologize for the late response, but the error is similar to the related bug #1131:

RuntimeError: The default implementation of __deepcopy__() for non-wrapper subclasses only works for subclass types that implement new_empty() and for which that function returns another instance of the same subclass. You should either properly implement new_empty() for your subclass or override __deepcopy__() if it is intended behavior for new_empty() to return an instance of a different type.

Super great! thanks!
