BUG in static_graph_collate function

[k-markov]

Hi, tried to make a StaticBatch from a list of Data objects and it crashed with:

    72 out = out.stores_as(elem)
    74 pattern = elem.pattern

---> 76 for key in elem.keys:
77 if key == 'transform':
78 out[key] = static_scaler_collate([data[key] for data in data_list])

TypeError: 'method' object is not iterable

Putting () after elem.keys fixes the problem.

Hi, this is due to an update to PyG's Data object in the last versions. They changed Data.keys from property to method. We'll find a solution for tsl's Data accordingly, thanks for the feedback!
