Composable Graph Data Transforms - DGL
WebDeep Graph Library. First, setting up our environment. # All 78 edges are stored in two numpy arrays. One for source endpoints. # while the other for destination endpoints. # Edges are directional in DGL; Make them bi-directional. print('We have %d nodes.'. % G.number_of_nodes ()) print('We have %d edges.'. WebDGL represents a directed graph as a DGLGraph object. You can construct a graph by specifying the number of nodes in the graph as well as the list of source and destination … WebTo create a homogeneous graph from Tensor data, use dgl.graph(). To create a heterogeneous graph from Tensor data, use dgl.heterograph(). To create a graph from other data sources, use dgl.* create ops. See Graph Create Ops.
