Question

Does the code only show the SAGPooling hierarchical model?

psp3dcg opened this issue 5 years ago · comments

Congratulation for your paper is accepted by ICML2019! I have run the code successfully but when I compare the results in your paper and run by your code, it seems that only the SAGPooling hierarchical mode is implemented. So I have some questions......
(1)I see torch-geometric document and find the implementations of ChebConv, SAGEConv and GATConv. Should I import them and replace GCNConv in class SAGPool in layer.py if I want to test SAGPool with other GNN methods?
(2)How can I implement the Global SAGPooling? Should I use three continue GCNConv , one Pooling layer and one readout layer to build the model. Could you ofter the source code?
(3)If I want to use SAGPooling(argument or 2-hop), how can I add sqaure adjacency matrix to "self.nhid"(I guess it is mixture of feature matrix and adjacency matrix,maybe I am wrong......)? For serial SAGPooling and parallel Pooling, how can I implement them, especially which GNNs are used in parallel Pooling?
Thanks~

oh, I failed running the code (SAGPooling uses GCNConv)on Proteins and NCI 109

the error message of Proteins shows like this:

Traceback (most recent call last):

test_acc,test_loss = test(model,test_loader)

IndexError: dimension specified as 0 but tensor has no dimensions

and the error message of NCI 109 is like this:

At first, I guess the dataset may has wrong data, but when I test SAGEConv on NCI 109,it succeeds......so I am confused......

I may find the problem, the computation in layer.py lacks of activate funtion tanh, in function forward(), score = self.score_layer(x,edge_index).squeeze()
score = self.non_linearity(score)#what the code loss but exists in paper,you should add it yourself
perm = topk(score, self.ratio, batch)

Without tanh, in i-th epoch the topk computation will overflow and return an index out of bounds of x
eg: index(2021) is out of bounds(0,2010)
