WebIn a forward pass, autograd does two things simultaneously: run the requested operation to compute a resulting tensor, and. maintain the operation’s gradient function in the DAG. The backward pass kicks off when .backward() is called on the DAG root. autograd then: computes the gradients from each .grad_fn, WebForward pass. Let's have something resembling more a neural network. The computational graph has been given below. You are going to initialize 3 large random tensors, and then do the operations as given in the computational graph. The final operation is the mean of the tensor, given by torch.mean (your_tensor).
