WebDeep Graph Library (DGL) is a Python package built for easy implementation of graph neural network model family, on top of existing DL frameworks (currently supporting PyTorch, MXNet and TensorFlow). WebThe dgl.sampling package contains operators and utilities for sampling from a graph via random walks, neighbor sampling, etc. They are typically used together with the DataLoader s in the dgl.dataloading package. The user guide Chapter 6: Stochastic Training on Large Graphs gives a holistic explanation on how different components work together. iron man gifts for boys
