PolyParamScheduler — mmengine 0.10.7 documentation

class mmengine.optim.PolyParamScheduler(optimizer, param_name, eta_min=0, power=1.0, begin=0, end=1000000000, last_step=-1, by_epoch=True, verbose=False)[source]¶

Decays the parameter value of each parameter group in a polynomial decay scheme.

Notice that such decay can happen simultaneously with other changes to the parameter value from outside this scheduler.

Parameters:

• optimizer (Optimizer or BaseOptimWrapper) – optimizer or Wrapped optimizer.

• param_name (str) – Name of the parameter to be adjusted, such as lr, momentum.

• eta_min (float) – Minimum parameter value at the end of scheduling. Defaults to 0.

• power (float) – The power of the polynomial. Defaults to 1.0.

• begin (int) – Step at which to start updating the parameters. Defaults to 0.

• end (int) – Step at which to stop updating the parameters. Defaults to INF.

• last_step (int) – The index of last step. Used for resume without state dict. Defaults to -1.

• by_epoch (bool) – Whether the scheduled parameters are updated by epochs. Defaults to True.

• verbose (bool) – Whether to print the value for each update. Defaults to False.

classmethod build_iter_from_epoch(*args, begin=0, end=1000000000, by_epoch=True, epoch_length=None, **kwargs)[source]¶

Build an iter-based instance of this scheduler from an epoch-based config.
