How to solve the error reported by directly running /Graph-Unlearning-main/lib_gnn_model/node_classifier.py?

If we change out = torch.matmul(out, self.weight) to out = self.lin(out) in Graph-Unlearning-main/lib_gnn_model/gcn/gcn_net_batch.py, it works, but by default citeseer training set set the accuracy is only about 40%.

What experiments did you run? I just ran the partition experiment, but I had some problems with the node_edge_unlearning experiment. Do you know if you have encountered, or have solved?

Hi, it seems you're using Python 3.8, which might be causing compatibility issues with certain packages, such as torch_geometric. I recommend checking the package versions to ensure they align with the supported Python version. I used to test on Python 3.6.10 and it should work.
