The text was updated … WebMay 13, 2024 · 1 Answer Sorted by: -2 Actually it is quite easy. You can access the gradient stored in a leaf tensor simply doing foo.grad.data. So, if you want to copy the gradient from one leaf to another, just do bar.grad.data.copy_ (foo.grad.data) after calling backward. Note that data is used to avoid keeping track of this operation in the computation graph.
