class dgl.dataloading.DistNodeDataLoader(g, nids, graph_sampler, device=None, **kwargs)[source]

Bases: dgl.distributed.dist_dataloader.DistDataLoader

Sampled graph data loader over nodes for distributed graph storage.

It wraps an iterable over a set of nodes, generating the list of message flow graphs (MFGs) as computation dependency of the said minibatch, on a distributed graph.

All the arguments have the same meaning as the single-machine counterpart dgl.dataloading.DataLoader except the first argument g which must be a dgl.distributed.DistGraph.
