(self, value: float, step: int)
Interface of report function.

        Since :class:`~optuna.trial.FrozenTrial` is not pruned,
        this report function does nothing.

            Please refer to :func:`~optuna.trial.FrozenTrial.should_prune`.

        Args:
            value:
                A value returned from the objective function.
            step:
                Step of the trial (e.g., Epoch of neural network training). Note that pruners
                assume that ``step`` starts at zero. For example,
                :class:`~optuna.pruners.MedianPruner` simply checks if ``step`` is less than
                ``n_warmup_steps`` as the warmup mechanism.
