Hi @rijobro ,
I think maybe you can simply use the convert_data_type utility here to convert to numpy array with wrap_sequence arg?
Thanks.

Sometimes after the dataloader,
transform[TraceKeys.ORIG_SIZE]is given as a list oftorch.Tensor. Callingnp.asarrayon this will return a numpy array containing a list (dtype=object), which causes problems. This fix will convert to a singletorch.Tensorif necessary and then convert that to a numpy array.I'm not quite sure the best way to add a test for this. I suspect all our inverses should also be run through the DataLoader, maybe with and
EnsureTypeat the end to simulate the numpy->torch conversion that we normally experience.Status
