docs: Same as :meth:`train()`, except:
  
          1. Add `extra_callbacks` to callbacks. The default value for
             `extra_callbacks` is :meth:`DEFAULT_CALLBACKS()`.
          2. Default value for `monitors` is :meth:`DEFAULT_MONITORS()`.
          3. Provide default values for every option except `steps_per_epoch`.
