+            ----------
+            optimizer (Optimizer): Wrapped optimizer.
+            max_lr (float or list): Upper learning rate boundaries in the cycle
+                for each parameter group.
+            total_steps (int): The total number of steps in the cycle. Note
+                that if a value is provided here, then it must be inferred by
+                providing a value for epochs and steps_per_epoch.
+                Default: None
+            epochs (int): The number of epochs to train for. This is used along
+                with steps_per_epoch in order to infer the total number of
+                steps in the cycle if a value for total_steps is not provided.
+                Default: None
+            steps_per_epoch (int): The number of steps per epoch to train for.
+                This is used along with epochs in order to infer the total
+                number of steps in the cycle if a value for total_steps is
+                not provided.
+                Default: None
+            pct_start (float): The percentage of the cycle (in number of steps)
+                spent increasing the learning rate.
+                Default: 0.3
+            anneal_strategy (str): {'cos', 'linear'}
+                Specifies the annealing strategy.
+                Default: 'cos'
+            cycle_momentum (bool): If ``True``, momentum is cycled inversely
+                to learning rate between 'base_momentum' and 'max_momentum'.
+                Default: True
+            base_momentum (float or list): Lower momentum boundaries in the
+                cycle for each parameter group. Note that momentum is cycled
+                inversely to learning rate; at the peak of a cycle, momentum is
+                'base_momentum' and learning rate is 'max_lr'.
+                Default: 0.85
+            max_momentum (float or list): Upper momentum boundaries in the
+                cycle for each parameter group. Functionally,
+                it defines the cycle amplitude (max_momentum - base_momentum).
+                Note that momentum is cycled inversely
+                to learning rate; at the start of a cycle, momentum is
+                'max_momentum' and learning rate is 'base_lr'
+                Default: 0.95
+            div_factor (float): Determines the initial learning rate via
+                initial_lr = max_lr/div_factor
+                Default: 25
+            final_div_factor (float): Determines the minimum learning rate via
+                min_lr = initial_lr/final_div_factor
+                Default: 1e4
+            last_epoch (int): The index of the last batch. This parameter is
+                used when resuming a training job. Since `step()` should be
+                invoked after each batch instead of after each epoch, this
+                number represents the total number of *batches* computed,
+                not the total number of epochs computed.
+                When last_epoch=-1, the schedule is started from the
+                beginning.
