@eddiebergman @karibbov are the tests passsing adequate a check for this to be merged?

[eddiebergman]

Good enough given what we've got I would say, if it causes issues. Then these issues should have an associated test so we can catch them in the future.

@eddiebergman
Do you wanna merge or I go with it?

[karibbov]

Updating torch > 2.0.0 requires torchvision >= 0.16. Then, we get an error from import torchvision. Anyone can decrypt the traceback?

Turns out AttributeError: 'int' object has no attribute 'nodes'
originates from here. When the dimension of the nested list -
graphs is 2 _nested_graphs.ndims sometimes returns 3 if the graphs in the dimension 2 are consistent, which causes the if clause to be taken and graphs list to be corrupted.
Made a short fix to it, that doesn't seem to break any tests

[Neeratyoy]

That's a great catch!
