Glad you found a solution, Marcel.
The issue is that a FaceGradVariable doesn't pickle itself properly. It stores
the state for a generic FaceVariable, but then it doesn't know how to rebuild
itself from that.
It either should
- pickle the correct information, which would also involve pickling phi
OR
- pickle itself as a plain FaceVariable, losing connection to phi on unpickling
(which is what your solution does)
Do you have an opinion on which behavior you'd like?
