Previously, if a graph module returned nested tuples (which end up being flattened per #6809), the GraphExecutor would not unflatten the result and instead naively returned only the first
k
of the flattened outputs (wherek = original top-level tuple size
). This PR fixes the output behavior of GraphExecutor to be the same as the VMExecutor ,by returning the outputs unflattened into nested lists respecting the original return type structure.cc @masahi @jroesch
I'm not super happy with the unflattening code, let me know if there's an easier/cleaner approach.Edit: I think it's clean enough now
