make the dataset featureless

[cxw-droid]

Hi,

How can I make a dataset (e.g,. MUTAG) featureless (e.g. make all features be 1) after I get the dataset from TUDataset(). When I tried to set each graph Data by data.x = torch.Tensor([1]*len(data.x)), the original graph Data.x is not changed, and when I tried to create a new list of graphs Data, the new list has no properties such as num_features.

So my questions is: Is there a convenient way to transform the default MUTAG dataset to a featureless one, at the same time keeping the original properties like num_features etc? Thanks.

transform = T.Constant(cat=False)
dataset = TUDataset(path, name='MUTAG', transform=transform)
