WebApr 8, 2024 · There are many learning rate scheduler provided by PyTorch in torch.optim.lr_scheduler submodule. All the scheduler needs the optimizer to update as first argument. Depends on the scheduler, you may need to provide more arguments to set up one. Let’s start with an example model. WebThe model is defined in two steps. We first specify the parameters of the model, and then outline how they are applied to the inputs. For operations that do not involve trainable parameters (activation functions such as ReLU, operations like maxpool), we generally use the torch.nn.functional module.
