Witryna26 lis 2024 · I thought gradients were supposed to accumulate in leaf_variables and this could only happen if requires_grad = True. For instance, weights and biases of layers such as conv and linear are leaf variables and require grad and when you do backward, grads will be accumulated for them and optimizer will update those leaf variables.
