        checkpoint, please change your optimizer to
        `tf.keras.optimizers.legacy.XXX` (e.g.
        `tf.keras.optimizers.legacy.Adam`).
    *   **TF1 compatibility.** The new optimizer does not support TF1 any more,
        so please use the legacy optimizer `tf.keras.optimizer.legacy.XXX`.
        We highly recommend to migrate your workflow to TF2 for stable
        support and new features.
