Awesome library, thank you for the good work!
I have a question about working with the Sampler. In particular, it doesn’t seem obvious how I can get a flat graph from NodeFlow. I’m looking to create a subgraph from a set of vertices, and then feed that subgraph into a GCN or the likes. I think the way to do that is to use the neighborhood sampler, but it returns a NodeFlow, and it’s not clear in the documentation how I can get a regular DGLGraph from it.
