WebAug 6, 2024 · It is correct that you lose gradients that way. In order to backpropagate through sparse matrices, you need to compute both edge_index and edge_weight (the first one holding the COO index and the second one holding the value for each edge). This way, gradients flow from edge_weight to your dense adjacency matrix..
