Webedge_weight ( torch.Tensor) – Unnormalized scalar weights on the edges. The shape is expected to be ( E ). Returns The normalized edge weight. Return type torch.Tensor Raises DGLError – Case 1: The edge weight is multi-dimensional. Currently this module only supports a scalar weight on each edge. WebDec 29, 2024 · So, we create a networkx graph by treating links in CORA as an edge list. Note that this creates the necessary nodes automatically. Note that this creates the necessary nodes automatically. We then add content-based features to each node by parsing cora.content file and indexing each unique word from 1 to the number of unique …
