WebbDecays the learning rate of each parameter group by gamma every step_size epochs. Notice that such decay can happen simultaneously with other changes to the learning rate from outside this scheduler. When last_epoch=-1, sets initial lr as lr. Parameters: optimizer ( Optimizer) – Wrapped optimizer. step_size ( int) – Period of learning rate decay. WebbThis can be useful when fine tuning a pre-trained network as frozen layers can be made trainable and added to the Optimizer as training progresses. Parameters: param_group ( dict) – Specifies what Tensors should be optimized along with group specific optimization options. load_state_dict(state_dict) Loads the optimizer state. Parameters:
