We should add an option to the PyTorch linker: coerce_to_numpy that defaults to True, and will apply to either CPU or GPU tensors? When False we don't force any conversion.
This mixed behavior is just unpredictable no?

Description
When doing an integration pass with pymc, there were type issues on the pymc side when given a torch tensor. To mitigate this, I migrated the linker to always return a numpy ndarray instead, and in the else case leave the tensor alone instead of forcing a device transfer.
