Subgraphx mismatch number of nodes for `BA2Motifs` dataset

[alirezadizaji]

Hi, I have tried subgraphx on ba2motif dataset to capture 50% of nodes, it mostly works well but sometimes it didn't like the following image. here is my subgraphx config: SubgraphX(self.model, num_classes=2, device=..., explain_graph=True, reward_method='mc_l_shapley', min_atoms=12, high2low=True, subgraph_building_method='split', verbose=True)

I have fixed it by replacing 'mc_shapley' with 'mc_l_shapley' for reward_method

Sorry the problem still remains with changing reward method
