WebOct 14, 2024 · 1. The difference between edge_weight and edge_attr is that edge_weight is the non-binary representation of the edge connecting two nodes, without edge_weight the edge connecting two nodes either exists or it doesn't (0 or 1) but with the weight the edge connecting the nodes can have arbitrary value. Whereas edge_attr means the features …
