Dgl batch_size
WebAs such, batch holds a total of 28,187 nodes involved for computing the embeddings of 128 “paper” nodes. Sampled nodes are always sorted based on the order in which they were sampled. Thus, the first batch ['paper'].batch_size nodes represent the set of original mini-batch nodes, making it easy to obtain the final output embeddings via slicing.
