I’d like to reference a feature tensor that is not node or edge feature, but a feature of the graph.
The options I understand I have are:
a) create a special type of node and put the graph-level features there.
b) have an external mechanism to look up the the feature tensor of the graph.
I’m wondering if there is any recommended way to handle graph level features. I’ve seen some older topics where the answer was that this is not supported. Is this still true? If yes, is there any reference implementation that deals with this?
