Does auto scheduler resume tuning load cost model necessary?

1 
def __init__(
    self,
    tasks,
    task_weights=None,
    objective_func=None,
    strategy="gradient",
    load_model_file: str = None,
    load_log_file: str = None,
    alpha: float = 0.2,
    beta: float = 2,
    gamma: float = 0.5,
    backward_window_size: int = 3,
    callbacks=None,
)

the init func has param load_model_file, so is it necessray to save the tuned model file and then import it?
