'multiclass_classification' is not a valid ModelMode

[WHYz919]

I try to implement the task of map classification in GNNExplainer, but the above error will be reported. My configuration is pytorch1.11.0+cuda11.3.

The interface changed slightly in current PyG master. You can either upgrade to PyG master, or use the interface from PyG 2.2, see https://github.com/pyg-team/pytorch_geometric/blob/2.2.0/examples/gnn_explainer.py.
