Explainer for LightGCN

[samhjy]

Hi All, I am rather new to this and need some help. Does GNNExplainer work with LightGCN? I am using the lightgcn.py example and the gnn_explainer.py provided, but am not sure how to integrate them since there is no data.x in the dataset, which is required for the explainer class.

explanation = explainer(data.x, data.edge_index, index=node_index)

Appreciate any input, thank you!
