A graph only contains one node

[nuaawh]

If a graph only contains one node (i.e., no edges, edges=[]), can the GCNConv layer be applied to such a problem ?
If so, will the GCNConv layer degenerate into the fully connected layer ?

Yes, for empty edge_index, GCNConv is indeed equivalent to a single torch.nn.Linear layer.
