Before submitting
This is just a proposed solution for sending namedtuples to the GPU without converting them to regular tuples. I am open to suggestions.
Sending data to devices seems to fit the pattern of recursively doing a thing to the elements of contaners. Good examples of this are
default_collate
anddefault_convert
in pytorch.https://github.com/pytorch/pytorch/blob/master/torch/utils/data/_utils/collate.py#L15
We could take this PR further by following the pattern in pytorch so that lightning works with all the same types. On the other hand, I'm not sure if this pattern satisfies the 'Simple code' requirement.
