Pytorch_geometric sparse to dense
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.. In code, this would look … WebApr 13, 2024 · README.md.

WebNote. Our sparse tensor format permits uncoalesced sparse tensors, where there may be duplicate coordinates in the indices; in this case, the interpretation is that the value at that index is the sum of all duplicate value entries. Uncoalesced tensors permit us to implement certain operators more efficiently. For the most part, you shouldn’t have to care whether … WebJul 4, 2024 · You can implement this multiplication yourself def sparse_dense_mul (s, d): i = s._indices () v = s._values () dv = d [i [0,:], i [1,:]] # get values from relevant entries of dense matrix return torch.sparse.FloatTensor (i, v * dv, s.size ())
