RuntimeError: Invalid index in scatterAdd
See original GitHub issue❓ Questions & Help
Hi, I created my own dataset in the way of ‘Cora’ dataset. And my dataset is Data(edge_index=[2, 24729], x=[803, 1], y=[803]). When I tried to run the example/gcn.py using my dataset, I got this error:
What’s the reason?

I’m not sure what you are trying to achieve. You do not need to save node indices in
x, but instead node features. Therefore,xshould have shape[num_nodes, num_features], so that each node hasnum_featuresfeatures. In your case,xshould therefore have size1004in the first dimension.You need to either filter out invalid edges in
edge_indexor add node features to all nodes, e.g., with shape [1004, 1].
