Error adapting code

Hey! I am facing some issues adapting your SimGNN code into my graph dataset. I keep encountering an error that says:

RuntimeError: Invalid index in scatterAdd at ../aten/src/TH/generic/THTensorEvenMoreMath.cpp:520

I even tried to change one of the training JSON files to the example of the labels and graph structure you gave. I also see a warning about size.

Am I missing something? Any help would be greatly appreciated.

When I add extra labels to match the number of nodes it seems to work:

{"graph_1": [[0, 1],[1, 2],[2, 3],[3, 4]],
"graph_2": [[0, 1], [1, 2], [1, 3], [3, 4], [2, 4]],
"labels_1": [2, 2, 2, 2, 1],
"labels_2": [2, 3, 2, 3 , 5],
"ged": 1}

I believe scatter has changed. Will take a look.

Hello,

I am also experiencing the same error. My graphs are similar but of different sizes. For your dataset, how did you pad the smaller graph to the larger graph? did you just add in extra "labels"?
