WebAug 30, 2024 · because torch.sum (torch.autograd.grad (Y [0],X) equals 2 and torch.sum (torch.autograd.grad (Y [1],X) equals 2 as well. It would be easy to calculate the Jacobian of Y w.r.t X and just sum over the dimensions of X. However, this is unfeasible memory-wise, as the functions I work with are neural networks with huge inputs and outputs.
