WebMar 4, 2024 · torch.matmul often returns different gradients for the same matrices, when the computation is done with an additional dimension (batched version). So if A and B are 2D matrices: C = torch. matmul ( A, B ) D = torch. matmul ( A. unsqueeze ( 0 ), B. unsqueeze ( 0 )). squeeze ( 0) Computing the gradient from C and D will give different results. WebSep 21, 2024 · I think most people know numpy. In numpy the transpose function does only transpose (Beside doing slightly different things). When reading the literature, many people say "conjugate transpose" (e.g. [1]), so implementing the transpose operation to do also a conjugate, it would lead to confusion.. I agree with @boeddeker here. I think we should …
