In this link I found some pooling layers modules：https://docs.dgl.ai/api/python/nn.pytorch.html#module-dgl.nn.pytorch.glob
feature is (N,∗) shaped and the return value of the forward function is (∗) shaped，I’m confused about the return value, what’s the significance of the result？
And there are some model implemented such as
，do you have some plan to add models such as
graph U-net or can I implement the model by myself with existing pooling layers relatively convenient?
