Arguments:

• predictor (Predictor[Any, Any]): Predictor that will be used in task.

• preprocess (Optional[Component], optional): Component executed before predictor.

• postprocess (Optional[Component], optional): Component executed after predictor.

• input_class (Type[Input]): Class for input validation.

• output_class (Type[Output]): Class for output validation.

• name (Optional[str], optional): Name for identification. If equals to None, class name will be used. Defaults to None.
