About Sampler

[ljhOfGithub]

Hello! I am the beginner of the graph neural network. I don't find the neighbor sampler in your repo, so how do you implement the algorithm:

Do you finish it in your own GCNConv class or the benchmark datasets? And how do you process the message passing between different layers? I can't find the parameter related to the layers, including the file gcon.py.
Thx.
