Web3 apr. 2024 · This worked because the loss calculation has happened before the no_grad and you keep calculating the gradients according to that loss calculation (which calculation had gradient enabled). Basically, you continue update the weights of your layers using the gradients calculated outside of the no_grad. When you actually use the no_grad: Web11 mei 2024 · To ensure that the overall activations are on the same scale during training and prediction, the activations of the active neurons have to be scaled appropriately.
