Thanks for the files!
Both throw an error:

ModuleNotFoundError: No module named ‘torch_geometric’

I’ll try to install the missing lib and try it again.
EDIT: After installing the missing lib, I could load the files:
>>> a = torch.load('data_0.pt')
>>> a
Data(edge_attr=Unsupported attribute type., edge_index=Unsupported attribute type., x=Unsupported attribute type., y=Unsupported attribute type.)
>>> b = torch.load('data_99.pth')
>>> b
Data(edge_attr=Unsupported attribute type., edge_index=Unsupported attribute type., x=Unsupported attribute type., y=Unsupported attribute type.)

Could you re-download the files and try it again or did you just upload your local files?
