        do_eval (`bool`, *optional*):
            Whether to run evaluation on the validation set or not. Will be set to `True` if `evaluation_strategy` is
            different from `"no"`. This argument is not directly used by [`Trainer`], it's intended to be used by your
            training/evaluation scripts instead. See the [example
            scripts](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/examples) for more details.
        do_predict (`bool`, *optional*, defaults to `False`):

        ignore_data_skip (`bool`, *optional*, defaults to `False`):
            When resuming training, whether or not to skip the epochs and batches to get the data loading at the same
            stage as in the previous training. If set to `True`, the training will begin faster (as that skipping step
            can take a long time) but will not yield the same results as the interrupted training would have.
        optim (`str` or [`training_args.OptimizerNames`], *optional*, defaults to `"adamw"`):
            The optimizer to use: adamw, or adafactor.
        length_column_name (`str`, *optional*, defaults to `"length"`):
            Column name for precomputed lengths. If the column exists, grouping by length will use these values rather
            than computing them on train startup. Ignored unless `group_by_length` is `True` and the dataset is an
            instance of `Dataset`.
        report_to (`str` or `List[str]`, *optional*, defaults to `"visualdl"`):
            The list of integrations to report the results and logs to.
            Supported platforms are `"visualdl"`/`"wandb"`/`"tensorboard"`.
            `"none"` for no integrations.
        wandb_api_key (`str`, *optional*):
            Weights & Biases (WandB) API key(s) for authentication with the WandB service.
        resume_from_checkpoint (`str`, *optional*):
            The path to a folder with a valid checkpoint for your model. This argument is not directly used by
            [`Trainer`], it's intended to be used by your training/evaluation scripts instead. See the [example
            scripts](https://github.com/PaddlePaddle/PaddleNLP/tree/develop/examples) for more details.
        flatten_param_grads (`bool`, *optional*):
            Whether use flatten_param_grads method in optimizer, only used on NPU devices. Default is `False`.
        skip_profile_timer (`bool`, *optional*):
            Whether skip profile timer, timer will record time usage of forward/ backward/ step, etc.
        distributed_dataloader (`bool`, *optional*):
            Whether to use distributed dataloader. Default is `False`.
