class TrainingArguments:
    """
    Configuration class for controlling all aspects of model training with the Trainer.
    TrainingArguments centralizes all hyperparameters, optimization settings, logging preferences, and infrastructure choices needed for training.

    [`HfArgumentParser`] can turn this class into
    [argparse](https://docs.python.org/3/library/argparse#module-argparse) arguments that can be specified on the
    command line.

    Parameters:
        output_dir (`str`, *optional*, defaults to `"trainer_output"`):
            The output directory where the model predictions and checkpoints will be written.

        > Training Duration and Batch Size

        per_device_train_batch_size (`int`, *optional*, defaults to 8):
            The batch size *per device*. The **global batch size** is computed as:
            `per_device_train_batch_size * number_of_devices` in multi-GPU or distributed setups.
        num_train_epochs(`float`, *optional*, defaults to 3.0):
            Total number of training epochs to perform (if not an integer, will perform the decimal part percents of
            the last epoch before stopping training).
        max_steps (`int`, *optional*, defaults to -1):
            Overrides `num_train_epochs`. If set to a positive number, the total number of training steps to perform.
            For a finite dataset, training is reiterated through the dataset (if all data is exhausted) until
            `max_steps` is reached.

        > Learning Rate & Scheduler

        learning_rate (`float`, *optional*, defaults to 5e-5):
            The initial learning rate for the optimizer. This is typically the peak learning rate when using a scheduler with warmup.
        lr_scheduler_type (`str` or [`SchedulerType`], *optional*, defaults to `"linear"`):
            The learning rate scheduler type to use. See [`SchedulerType`] for all possible values. Common choices:
                - "linear" = [`get_linear_schedule_with_warmup`]
                - "cosine" = [`get_cosine_schedule_with_warmup`]
                - "constant" =  [`get_constant_schedule`]
                - "constant_with_warmup" = [`get_constant_schedule_with_warmup`]

            The extra arguments for the lr_scheduler. See the documentation of each scheduler for possible values.
        warmup_steps (`int` or `float`, *optional*, defaults to 0):
            Number of steps for a linear warmup from 0 to `learning_rate`. Warmup helps stabilize training in the initial phase. Can be:
                - An integer: exact number of warmup steps
                - A float in range [0, 1): interpreted as ratio of total training steps

        > Optimizer

        optim (`str` or [`training_args.OptimizerNames`], *optional*, defaults to `"adamw_torch"` (for torch>=2.8 `"adamw_torch_fused"`)):
            The optimizer to use. Common options:
                - `"adamw_torch"`: PyTorch's AdamW (recommended default)
                - `"adamw_torch_fused"`: Fused AdamW kernel
                - `"adamw_hf"`: HuggingFace's AdamW implementation
                - `"sgd"`: Stochastic Gradient Descent with momentum
                - `"adafactor"`: Memory-efficient optimizer for large models
                - `"adamw_8bit"`: 8-bit AdamW (requires bitsandbytes)
                See [`OptimizerNames`] for the complete list.
        optim_args (`str`, *optional*):
            Optional arguments that are supplied to optimizers such as AnyPrecisionAdamW, AdEMAMix, and GaLore.
        weight_decay (`float`, *optional*, defaults to 0):
            Weight decay coefficient applied by the optimizer (not the loss function). Adds L2
            regularization to prevent overfitting by penalizing large weights. Automatically
            excluded from bias and LayerNorm parameters. Typical values: 0.01 (standard), 0.1
            (stronger regularization), 0.0 (no regularization).
        adam_beta1 (`float`, *optional*, defaults to 0.9):
            The exponential decay rate for the first moment estimates (momentum) in Adam-based
            optimizers. Controls how much history of gradients to retain.
        adam_beta2 (`float`, *optional*, defaults to 0.999):
            The exponential decay rate for the second moment estimates (variance) in Adam-based
            optimizers. Controls adaptive learning rate scaling.
        adam_epsilon (`float`, *optional*, defaults to 1e-8):
            Epsilon value for numerical stability in Adam-based optimizers. Prevents division by
            zero in the denominator of the update rule.
        optim_target_modules (`Union[str, list[str]]`, *optional*):
            The target modules to optimize, i.e. the module names that you would like to train.
            Currently used for the [GaLore algorithm](https://huggingface.co/papers/2403.03507) and [APOLLO algorithm](https://huggingface.co/papers/2412.05270).
            See [GaLore implementation](https://github.com/jiaweizzhao/GaLore) and [APOLLO implementation](https://github.com/zhuhanqing/APOLLO) for more details.
            You need to make sure to pass a valid GaLore or APOLLO optimizer, e.g., one of: "apollo_adamw", "galore_adamw", "galore_adamw_8bit", "galore_adafactor" and make sure that the target modules are `nn.Linear` modules only.

        > Regularization & Training Stability

        gradient_accumulation_steps (`int`, *optional*, defaults to 1):
            Number of update steps to accumulate gradients before performing a backward/update pass.
            Simulates larger batch sizes without additional memory. Effective batch size =
            `per_device_train_batch_size × num_devices × gradient_accumulation_steps`.
            > [!TIP]
            > When using gradient accumulation, one "step" is counted as one step with a backward pass. Therefore, logging, evaluation, and saving will occur every `gradient_accumulation_steps × xxx_step` training examples.
        average_tokens_across_devices (`bool`, *optional*, defaults to `True`):
            Whether or not to average tokens across devices. If enabled, will use all_reduce to synchronize
            num_tokens_in_batch for precise loss calculation. Reference:
            https://github.com/huggingface/transformers/issues/34242
        max_grad_norm (`float`, *optional*, defaults to 1.0):
            Maximum gradient norm for gradient clipping. Applied after backward pass, before
            optimizer step. Prevents gradient explosion by scaling down gradients when their global
            norm exceeds this threshold. Set to 0 to disable clipping. Typical values:
            1.0 (standard), 0.5 (more conservative), 5.0 (less aggressive).
        label_smoothing_factor (`float`, *optional*, defaults to 0.0):
            Label smoothing factor to prevent overconfidence. Replaces hard 0/1 targets with soft
            targets: 0 becomes `ε/num_labels` and 1 becomes `1 - ε + ε/num_labels`, where
            ε = `label_smoothing_factor`. Zero means no smoothing. Typical range: 0.0 to 0.1.

        > Mixed Precision Training

        bf16 (`bool`, *optional*, defaults to `False`):
            Enable bfloat16 (BF16) mixed precision training
            Generally preferred over FP16 due to better numerical stability and no loss scaling required.
        fp16 (`bool`, *optional*, defaults to `False`):
            Enable float16 (FP16) mixed precision training.
            Consider using BF16 instead if your hardware supports it.
        bf16_full_eval (`bool`, *optional*, defaults to `False`):
            Use full BF16 precision for evaluation (not just mixed precision). Faster and saves
            memory but may affect metric values slightly. Only applies during evaluation.
        fp16_full_eval (`bool`, *optional*, defaults to `False`):
            Use full FP16 precision for evaluation (not just mixed precision). Faster and saves
            memory but may affect metric values slightly. Only applies during evaluation.
        tf32 (`bool`, *optional*):
            Enable TensorFloat-32 (TF32) mode on Ampere and newer GPUs. TF32 uses 19-bit precision
            for matrix multiplications (instead of FP32's 23-bit), providing up to 8x speedup with
            negligible accuracy loss. Default depends on PyTorch version. See
            [TF32 docs](https://huggingface.co/docs/transformers/perf_train_gpu_one#tf32).

        > Gradient Checkpointing

        gradient_checkpointing (`bool`, *optional*, defaults to `False`):
            Enable gradient checkpointing to trade compute for memory. Reduces memory usage by
            clearing activations during forward pass and recomputing them during backward pass.
            Enables training larger models or batch sizes at the cost of ~20% slower training.
        gradient_checkpointing_kwargs (`dict`, *optional*, defaults to `None`):
            Keyword arguments passed to `gradient_checkpointing_enable()`.

        > Compilation

        torch_compile (`bool`, *optional*, defaults to `False`):
            Compile the model using PyTorch 2.0's `torch.compile()` for faster training. Can provide
            20-50% speedup with no code changes. Uses default compilation settings unless
            `torch_compile_backend` or `torch_compile_mode` are specified.
        torch_compile_backend (`str`, *optional*):
            Backend for `torch.compile()`. If set, automatically enables `torch_compile`. Options
            include `"inductor"` (default), `"aot_eager"`, `"cudagraphs"`. Backends vary by PyTorch
            version - see PyTorch docs for available options.
        torch_compile_mode (`str`, *optional*):
            Compilation mode for `torch.compile()`. If set, automatically enables `torch_compile`.
            Options: `"default"`, `"reduce-overhead"` (minimize Python overhead), `"max-autotune"`
            (aggressive optimization, slower compile time).

        > Kernels

        use_liger_kernel (`bool`, *optional*, defaults to `False`):
            Enable [Liger Kernel](https://github.com/linkedin/Liger-Kernel) optimizations. Increases
            multi-GPU throughput by ~20% and reduces memory usage by ~60%. Works with Flash Attention,
            FSDP, and DeepSpeed. Currently supports Llama, Mistral, Mixtral, and Gemma models.
        liger_kernel_config (`Optional[dict]`, *optional*):
            Configuration for Liger Kernel. Passed as kwargs to `_apply_liger_kernel_to_instance()`.
            Options typically include: `"rope"`, `"swiglu"`, `"cross_entropy"`,
            `"fused_linear_cross_entropy"`, `"rms_norm"`. If `None`, uses default configuration.

        > Additional Optimizations

        use_cache (`bool`, *optional*, defaults to `False`):
            Whether or not to enable cache for the model. For training, this is usually not needed apart from some PEFT methods that uses `past_key_values`.
        neftune_noise_alpha (`Optional[float]`):
            If not `None`, this will activate NEFTune noise embeddings. This can drastically improve model performance
            for instruction fine-tuning. Check out the [original paper](https://huggingface.co/papers/2310.05914) and the
            [original code](https://github.com/neelsjain/NEFTune). Support transformers `PreTrainedModel` and also
            `PeftModel` from peft. The original paper used values in the range [5.0, 15.0].
        torch_empty_cache_steps (`int`, *optional*):
            Number of steps to wait before calling `torch.<device>.empty_cache()`. If left unset or set to None, cache will not be emptied.
            This can help avoid CUDA out-of-memory errors by lowering peak VRAM usage at a cost of about [10% slower performance](https://github.com/huggingface/transformers/issues/31372).
        auto_find_batch_size (`bool`, *optional*, defaults to `False`)
            Whether to find a batch size that will fit into memory automatically through exponential decay, avoiding
            CUDA Out-of-Memory errors.

        > Logging & Monitoring Training

        logging_strategy (`str` or [`~trainer_utils.IntervalStrategy`], *optional*, defaults to `"steps"`):
            The logging strategy to adopt during training. Possible values are:
                - `"no"`: No logging is done during training.
                - `"epoch"`: Logging is done at the end of each epoch.
                - `"steps"`: Logging is done every `logging_steps`.
        logging_steps (`int` or `float`, *optional*, defaults to 500):
            Number of update steps between two logs if `logging_strategy="steps"`. Should be an integer or a float in
            range `[0,1)`. If smaller than 1, will be interpreted as ratio of total training steps.
        logging_first_step (`bool`, *optional*, defaults to `False`):
            Whether to log the first `global_step` or not.
        log_on_each_node (`bool`, *optional*, defaults to `True`):
            In multinode distributed training, whether to log using `log_level` once per node, or only on the main
            node.
        logging_nan_inf_filter (`bool`, *optional*, defaults to `True`):
             Filter out NaN and Inf losses when logging. If `True`, replaces NaN/Inf losses with the
            average of recent valid losses. Does not affect gradient computation, only logging.
        include_num_input_tokens_seen (`Optional[Union[str, bool]]`, *optional*, defaults to "no"):
            Whether to track the number of input tokens seen. Must be one of ["all", "non_padding", "no"] or a boolean value which map to "all" or "no".
            May be slower in distributed training as gather operations must be called.

        > Logging

        log_level (`str`, *optional*, defaults to `passive`):
            Logging level for the main process. Options: `"debug"`, `"info"`, `"warning"`, `"error"`,
            `"critical"`, or `"passive"` (doesn't change the current Transformers logging level,
            which defaults to `"warning"`)
        log_level_replica (`str`, *optional*, defaults to `"warning"`):
            Logging level for replica processes in distributed training. Same options as `log_level`.
        disable_tqdm (`bool`, *optional*):
            Disable tqdm progress bars. Defaults to `True` if `log_level` is warning or lower, `False` otherwise.

        > Experiment Tracking Integration

        report_to (`str` or `list[str]`, *optional*, defaults to `"none"`):
            The list of integrations to report the results and logs to. Supported platforms are `"azure_ml"`,
            `"clearml"`, `"codecarbon"`, `"comet_ml"`, `"dagshub"`, `"dvclive"`, `"flyte"`, `"mlflow"`, `"swanlab"`,
            `"tensorboard"`, `"trackio"` and `"wandb"`. Use `"all"` to report to all integrations installed, `"none"`
            for no integrations.
        run_name (`str`, *optional*):
            A descriptor for the run. Typically used for [trackio](https://github.com/gradio-app/trackio),
            [wandb](https://www.wandb.com/), [mlflow](https://www.mlflow.org/), [comet](https://www.comet.com/site) and
            [swanlab](https://swanlab.cn) logging.
        project (`str`, *optional*, defaults to `"huggingface"`):

            `'username/reponame'` or `'orgname/reponame'`, or just `'reponame'` in which case the Space will be
            created in the currently-logged-in Hugging Face user's namespace. If `None`, will log to a local directory.
            Note that this Space will be public unless you set `hub_private_repo=True` or your organization's default
            is to create private Spaces."

        > Evaluation

        eval_strategy (`str` or [`~trainer_utils.IntervalStrategy`], *optional*, defaults to `"no"`):
            When to run evaluation. Options:
            - `"no"`: No evaluation during training
            - `"steps"`: Evaluate every `eval_steps`
            - `"epoch"`: Evaluate at the end of each epoch
        eval_steps (`int` or `float`, *optional*):
            Number of update steps between two evaluations if `eval_strategy="steps"`. Will default to the same
            value as `logging_steps` if not set. Should be an integer or a float in range `[0,1)`. If smaller than 1,
            will be interpreted as ratio of total training steps.
        eval_delay (`float`, *optional*):
            Number of epochs or steps to wait for before the first evaluation can be performed, depending on the
            eval_strategy.
        per_device_eval_batch_size (`int`, *optional*, defaults to 8):
            The batch size per device accelerator core/CPU for evaluation.
        prediction_loss_only (`bool`, *optional*, defaults to `False`):
            When performing evaluation and generating predictions, only returns the loss.
        eval_on_start (`bool`, *optional*, defaults to `False`):
            Whether to perform a evaluation step (sanity check) before the training to ensure the validation steps works correctly.
        eval_do_concat_batches (`bool`, *optional*, defaults to `True`):
            Whether to recursively concat inputs/losses/labels/predictions across batches. If `False`,
            will instead store them as lists, with each batch kept separate.
        eval_use_gather_object (`bool`, *optional*, defaults to `False`):
            Whether to run recursively gather object in a nested list/tuple/dictionary of objects from all devices. This should only be enabled if users are not just returning tensors, and this is actively discouraged by PyTorch.
            This is useful when the labels structure is non standard, like in computer vision tasks.
        eval_accumulation_steps (`int`, *optional*):
            Number of predictions steps to accumulate the output tensors for, before moving the results to the CPU. If
            left unset, the whole predictions are accumulated on the device accelerator before being moved to the CPU (faster but
            requires more memory).

        > Metrics Computation

        include_for_metrics (`list[str]`, *optional*, defaults to `[]`):
            Include additional data in the `compute_metrics` function if needed for metrics computation.
            Possible options to add to `include_for_metrics` list:
            - `"inputs"`: Input data passed to the model, intended for calculating input dependent metrics.
            - `"loss"`: Loss values computed during evaluation, intended for calculating loss dependent metrics.
        batch_eval_metrics (`bool`, *optional*, defaults to `False`):
            If set to `True`, evaluation will call compute_metrics at the end of each batch to accumulate statistics
            rather than saving all eval logits in memory. When set to `True`, you must pass a compute_metrics function
            that takes a boolean argument `compute_result`, which when passed `True`, will trigger the final global
            summary statistics from the batch-level summary statistics you've accumulated over the evaluation set.

        > Checkpointing & Saving

        save_only_model (`bool`, *optional*, defaults to `False`):
            Save only model weights, not optimizer/scheduler/RNG state. Significantly reduces
            checkpoint size but prevents resuming training from the checkpoint. Use when you only
            need the trained model for inference, not continued training.
            You can only load the model using `from_pretrained` with this option set to `True`.
        save_strategy (`str` or [`~trainer_utils.SaveStrategy`], *optional*, defaults to `"steps"`):
            The checkpoint save strategy to adopt during training. Possible values are:
                - `"no"`: No save is done during training.
                - `"epoch"`: Save is done at the end of each epoch.
                - `"steps"`: Save is done every `save_steps`.
                - `"best"`: Save is done whenever a new `best_metric` is achieved.
        save_steps (`int` or `float`, *optional*, defaults to 500):
            Number of updates steps before two checkpoint saves if `save_strategy="steps"`. Should be an integer or a
            float in range `[0,1)`. If smaller than 1, will be interpreted as ratio of total training steps.
        save_on_each_node (`bool`, *optional*, defaults to `False`):
            When doing multi-node distributed training, whether to save models and checkpoints on each node, or only on
            the main one.
            This should not be activated when the different nodes use the same storage as the files will be saved with
            the same names for each node.
        save_total_limit (`int`, *optional*):
            Maximum number of checkpoints to keep. Deletes older checkpoints in `output_dir`. When
            `load_best_model_at_end=True`, the best checkpoint is always retained plus the most
            recent ones. For example, `save_total_limit=5` keeps the 4 most recent plus the best
        enable_jit_checkpoint (`bool`, *optional*, defaults to `False`):
            Enable Just-In-Time checkpointing on SIGTERM signal for graceful termination on
            preemptible workloads. **Important**: Configure your orchestrator's graceful shutdown
            period to allow sufficient time. For Kubernetes, set `terminationGracePeriodSeconds`
            (default 30s is usually insufficient). For Slurm, use `--signal=USR1@<seconds>`.
            Required grace period ≥ longest iteration time + checkpoint save time.

        > Hugging Face Hub Integration

        push_to_hub (`bool`, *optional*, defaults to `False`):
            Whether or not to push the model to the Hub every time the model is saved. If this is activated,
            `output_dir` will begin a git directory synced with the repo (determined by `hub_model_id`) and the content
            will be pushed each time a save is triggered (depending on your `save_strategy`). Calling
            [`~Trainer.save_model`] will also trigger a push.
        hub_token (`str`, *optional*):
            The token to use to push the model to the Hub. Will default to the token in the cache folder obtained with
            `hf auth login`.
        hub_private_repo (`bool`, *optional*):
            Whether to make the repo private. If `None` (default), the repo will be public unless the organization's
            default is private. This value is ignored if the repo already exists. If reporting to Trackio with
            deployment to Hugging Face Spaces enabled, the same logic determines whether the Space is private.
        hub_model_id (`str`, *optional*):
            The name of the repository to keep in sync with the local *output_dir*. It can be a simple model ID in
            which case the model will be pushed in your namespace. Otherwise it should be the whole repository name,
            for instance `"user_name/model"`, which allows you to push to an organization you are a member of with
            `"organization_name/model"`. Will default to `user_name/output_dir_name` with *output_dir_name* being the
            name of `output_dir`.
        hub_strategy (`str` or [`~trainer_utils.HubStrategy`], *optional*, defaults to `"every_save"`):
            Defines what and when to push to Hub. Options:
                - `"end"`: Push only at the end of training
                - `"every_save"`: Push on each save (async to not block training)
                - `"checkpoint"`: Like `"every_save"` plus push latest checkpoint to `"last-checkpoint"` subfolder for easy resuming
                - `"all_checkpoints"`: Push all checkpoints as they appear
        hub_always_push (`bool`, *optional*, defaults to `False`):
            Unless this is `True`, the `Trainer` will skip pushing a checkpoint when the previous push is not finished.
        hub_revision (`str`, *optional*):
            The revision to use when pushing to the Hub. Can be a branch name, a tag, or a commit hash.

        > Best Model Tracking

        load_best_model_at_end (`bool`, *optional*, defaults to `False`):
            Load the best checkpoint at the end of training. Requires `eval_strategy` to be set.
            When enabled, the best checkpoint is always saved (see `save_total_limit`).
            <Tip>
            When `True`, `save_strategy` must match `eval_strategy` (unless `save_strategy` is `"best"`), and if using `"steps"`,
            `save_steps` must be a multiple of `eval_steps`.
            </Tip>
        metric_for_best_model (`str`, *optional*):
            Metric to use for comparing models when `load_best_model_at_end=True`. Must be a metric
            name returned by evaluation, with or without the `"eval_"` prefix. Defaults to `"loss"`.
            If you set this, `greater_is_better` will default to `True` unless the name ends with
            `"loss"`. Examples: `"accuracy"`, `"f1"`, `"eval_bleu"`.
        greater_is_better (`bool`, *optional*):
            Whether higher metric values are better. Defaults based on `metric_for_best_model`:
            `True` if the metric name doesn't end in `"loss"`, `False` otherwise.

        > Resuming Training

        ignore_data_skip (`bool`, *optional*, defaults to `False`):
            When resuming training, skip fast-forwarding through the dataset to reach the previous
            state. If `True`, training starts from the beginning of the dataset (faster resume but
            results won't match interrupted training). If `False`, skips seen data (slower resume
            but exact continuation).
        restore_callback_states_from_checkpoint (`bool`, *optional*, defaults to `False`):
            Restore callback states from checkpoint when resuming. If `True`, will override callbacks
            passed to Trainer if they exist in the checkpoint.

        > Reproducibility

        full_determinism (`bool`, *optional*, defaults to `False`)
            If `True`, [`enable_full_determinism`] is called instead of [`set_seed`] to ensure reproducible results in
            distributed training. Important: this will negatively impact the performance, so only use it for debugging.
        seed (`int`, *optional*, defaults to 42):
            Random seed that will be set at the beginning of training. To ensure reproducibility across runs, use the
            [`~Trainer.model_init`] function to instantiate the model if it has some randomly initialized parameters.
        data_seed (`int`, *optional*):
            Random seed to be used with data samplers. If not set, random generators for data sampling will use the
            same seed as `seed`. This can be used to ensure reproducibility of data sampling, independent of the model
            seed.

        > Hardware Configuration

        use_cpu (`bool`, *optional*, defaults to `False`):
            Whether or not to use cpu. If set to False, we will use the available torch device/backend.

        > Accelerate Configuration

        accelerator_config (`str`, `dict`, or `AcceleratorConfig`, *optional*):
            Configuration for the internal Accelerate integration. Can be:
                - Path to JSON config file: `"accelerator_config.json"`
                - Dictionary with config options
                - `AcceleratorConfig` instance
            Key options:
                - `split_batches` (`bool`, defaults to `False`): Whether to split batches across devices.
                    If `True`, actual batch size is the same on all devices (total must be divisible by
                    num_processes). If `False`, each device gets the specified batch size.
                - `dispatch_batches` (`bool`): If `True`, only main process iterates through dataloader
                    and dispatches batches to devices. Defaults to `True` for `IterableDataset`, `False`
                    otherwise.
                - `even_batches` (`bool`, defaults to `True`): Duplicate samples from dataset start to
                    ensure all workers get equal batch sizes.
                - `use_seedable_sampler` (`bool`, defaults to `True`): Use fully seedable random sampler
                    for reproducibility.
                - `use_configured_state` (`bool`, defaults to `False`): Use pre-initialized
                    `AcceleratorState`/`PartialState` instead of creating new one. May cause issues with
                    hyperparameter tuning.

        parallelism_config (`ParallelismConfig`, *optional*):
            Parallelism configuration for the training run. Requires Accelerate `1.10.1`

        > Dataloader

        dataloader_drop_last (`bool`, *optional*, defaults to `False`):
            Whether to drop the last incomplete batch (if the length of the dataset is not divisible by the batch size)
            or not.
        dataloader_num_workers (`int`, *optional*, defaults to 0):
            Number of subprocesses to use for data loading (PyTorch only). 0 means that the data will be loaded in the
            main process.
        dataloader_pin_memory (`bool`, *optional*, defaults to `True`):
            Whether you want to pin memory in data loaders or not. Will default to `True`.
        dataloader_persistent_workers (`bool`, *optional*, defaults to `False`):
            If True, the data loader will not shut down the worker processes after a dataset has been consumed once.
            This allows to maintain the workers Dataset instances alive. Can potentially speed up training, but will
            increase RAM usage. Will default to `False`.
        dataloader_prefetch_factor (`int`, *optional*):
            Number of batches loaded in advance by each worker.
            2 means there will be a total of 2 * num_workers batches prefetched across all workers.
        remove_unused_columns (`bool`, *optional*, defaults to `True`):
            Whether or not to automatically remove the columns unused by the model forward method.
        label_names (`list[str]`, *optional*):
            The list of keys in your dictionary of inputs that correspond to the labels.
            Will eventually default to the list of argument names accepted by the model that contain the word "label",
            except if the model used is one of the `XxxForQuestionAnswering` in which case it will also include the
            `["start_positions", "end_positions"]` keys.
            You should only specify `label_names` if you're using custom label names or if your model's `forward` consumes multiple label tensors (e.g., extractive QA).
        train_sampling_strategy (`str`, *optional*, defaults to `"random"`):
            The sampler to use for the training dataloader. Possible values are:

                - `"random"`: Uses `RandomSampler` (default).
                - `"sequential"`: Uses `SequentialSampler`.
                - `"group_by_length"`: Uses `LengthGroupedSampler` to group samples of roughly the same length
                  together (to minimize padding and be more efficient).

            Note: When using an `IterableDataset`, this argument is ignored.
        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 `train_sampling_strategy` is `"group_by_length"` and the dataset
            is an instance of `Dataset`.

        > DDP (DistributedDataParallel)

        ddp_find_unused_parameters (`bool`, *optional*):
            When using distributed training, the value of the flag `find_unused_parameters` passed to
            `DistributedDataParallel`. Will default to `False` if gradient checkpointing is used, `True` otherwise.
        ddp_bucket_cap_mb (`int`, *optional*):
            When using distributed training, the value of the flag `bucket_cap_mb` passed to `DistributedDataParallel`.
        ddp_broadcast_buffers (`bool`, *optional*):
            When using distributed training, the value of the flag `broadcast_buffers` passed to
            `DistributedDataParallel`. Will default to `False` if gradient checkpointing is used, `True` otherwise.
        ddp_backend (`str`, *optional*):
            The backend to use for distributed training. Must be one of `"nccl"`, `"mpi"`, `"xccl"`, `"gloo"`, `"hccl"`.
        ddp_timeout (`int`, *optional*, defaults to 1800):
            The timeout for `torch.distributed.init_process_group` calls, used to avoid GPU socket timeouts when
            performing slow operations in distributed runnings. Please refer to the [PyTorch documentation](https://pytorch.org/docs/stable/distributed.html#torch.distributed.init_process_group) for more
            information.

        > FSDP (Fully Sharded Data Parallel)

        fsdp (`bool`, `str` or list of [`~trainer_utils.FSDPOption`], *optional*, defaults to `None`):

                - `"full_shard"`: Shard parameters, gradients, and optimizer states (most memory efficient)
                - `"shard_grad_op"`: Shard only optimizer states and gradients (ZeRO-2)
                - `"hybrid_shard"`: Full shard within nodes, replicate across nodes
                - `"hybrid_shard_zero2"`: Shard gradients/optimizer within nodes, replicate across nodes
                - `"offload"`: Offload parameters and gradients to CPU (only with `"full_shard"` or
                    `"shard_grad_op"`)
                - `"auto_wrap"`: Automatically wrap layers using `default_auto_wrap_policy`
        fsdp_config (`str` or `dict`, *optional*):
            Config to be used with fsdp (Pytorch Distributed Parallel Training). The value is either a location of
            fsdp json config file (e.g., `fsdp_config.json`) or an already loaded json file as `dict`.

            A List of config and its options:
                - fsdp_version (`int`, *optional*, defaults to `1`):
                    The version of FSDP to use. Defaults to 1.

                    FSDP's minimum number of parameters for Default Auto Wrapping. (useful only when `fsdp` field is
                    passed).
                - transformer_layer_cls_to_wrap (`list[str]`, *optional*):
                    List of transformer layer class names (case-sensitive) to wrap, e.g, `BertLayer`, `GPTJBlock`,
                    `T5Block` .... (useful only when `fsdp` flag is passed).
                - backward_prefetch (`str`, *optional*)
                    FSDP's backward prefetch mode. Controls when to prefetch next set of parameters (useful only when
                    `fsdp` field is passed).

                    A list of options along the following:

                    - `"backward_pre"` : Prefetches the next set of parameters before the current set of parameter's
                      gradient computation.
                    - `"backward_post"` : This prefetches the next set of parameters after the current set of
                      parameter's gradient computation.
                - forward_prefetch (`bool`, *optional*, defaults to `False`)
                    FSDP's forward prefetch mode (useful only when `fsdp` field is passed).
                     If `"True"`, then FSDP explicitly prefetches the next upcoming all-gather while executing in the
                     forward pass.
                - limit_all_gathers (`bool`, *optional*, defaults to `False`)
                    FSDP's limit_all_gathers (useful only when `fsdp` field is passed).
                     If `"True"`, FSDP explicitly synchronizes the CPU thread to prevent too many in-flight
                     all-gathers.
                - use_orig_params (`bool`, *optional*, defaults to `True`)
                    If `"True"`, allows non-uniform `requires_grad` during init, which means support for interspersed
                    frozen and trainable parameters. Useful in cases such as parameter-efficient fine-tuning. Please
                    refer this
                    [blog](https://dev-discuss.pytorch.org/t/rethinking-pytorch-fully-sharded-data-parallel-fsdp-from-first-principles/1019
                - sync_module_states (`bool`, *optional*, defaults to `True`)
                    If `"True"`, each individually wrapped FSDP unit will broadcast module parameters from rank 0 to
                    ensure they are the same across all ranks after initialization
                - cpu_ram_efficient_loading (`bool`, *optional*, defaults to `False`)
                    If `"True"`, only the first process loads the pretrained model checkpoint while all other processes
                    have empty weights.  When this setting as `"True"`, `sync_module_states` also must to be `"True"`,
                    otherwise all the processes except the main process would have random weights leading to unexpected
                    behaviour during training.
                - activation_checkpointing (`bool`, *optional*, defaults to `False`):
                    If `"True"`, activation checkpointing is a technique to reduce memory usage by clearing activations of
                    certain layers and recomputing them during a backward pass. Effectively, this trades extra
                    computation time for reduced memory usage.
                - xla (`bool`, *optional*, defaults to `False`):
                    Whether to use PyTorch/XLA Fully Sharded Data Parallel Training. This is an experimental feature
                    and its API may evolve in the future.
                - xla_fsdp_settings (`dict`, *optional*)
                    The value is a dictionary which stores the XLA FSDP wrapping parameters.

                    For a complete list of options, please see [here](
                    https://github.com/pytorch/xla/blob/master/torch_xla/distributed/fsdp/xla_fully_sharded_data_parallel.py).
                - xla_fsdp_grad_ckpt (`bool`, *optional*, defaults to `False`):
                    Will use gradient checkpointing over each nested XLA FSDP wrapped layer. This setting can only be
                    used when the xla flag is set to true, and an auto wrapping policy is specified through
                    fsdp_min_num_params or fsdp_transformer_layer_cls_to_wrap.

        > DeepSpeed

        deepspeed (`str` or `dict`, *optional*):
             Enable [DeepSpeed](https://github.com/deepspeedai/DeepSpeed) integration. Value is either:
                - Path to DeepSpeed JSON config file: `"ds_config.json"`
                - Loaded config as dictionary
          > [!TIP]
          > If using ZeRO initialization, instantiate your model *after* initializing
          `TrainingArguments`, otherwise ZeRO won't be applied.

        > Debugging & Profiling (Experimental)

        debug (`str` or list of [`~debug_utils.DebugOption`], *optional*, defaults to `""`):
            Enable one or more debug features. This is an experimental feature.
            Possible options are:
            - "underflow_overflow": detects overflow in model's input/outputs and reports the last frames that led to
              the event
            - "tpu_metrics_debug": print debug metrics on TPU
        skip_memory_metrics (`bool`, *optional*, defaults to `True`):
            Whether to skip adding of memory profiler reports to metrics. This is skipped by default because it slows
            down the training and evaluation speed.

        > External Script Flags (not used by Trainer)

        do_train (`bool`, *optional*, defaults to `False`):
            Whether to run training or not. 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/huggingface/transformers/tree/main/examples) for more details.
        do_eval (`bool`, *optional*):
            Whether to run evaluation on the validation set or not. Will be set to `True` if `eval_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

                gradient is computed or applied to the model.

        A method that regroups all arguments linked to synchronizing checkpoints with the Hub.

        <Tip>

        Calling this method will set `self.push_to_hub` to `True`, which means the `output_dir` will begin a git
        directory synced with the repo (determined by `model_id`) and the content will be pushed each time a save is
        triggered (depending on your `self.save_strategy`). Calling [`~Trainer.save_model`] will also trigger a push.

        </Tip>

        Args:
            model_id (`str`):
                The name of the repository to keep in sync with the local *output_dir*. It can be a simple model ID in
                which case the model will be pushed in your namespace. Otherwise it should be the whole repository
                name, for instance `"user_name/model"`, which allows you to push to an organization you are a member of
                with `"organization_name/model"`.
            strategy (`str` or [`~trainer_utils.HubStrategy`], *optional*, defaults to `"every_save"`):
                Defines the scope of what is pushed to the Hub and when. Possible values are:

                - `"end"`: push the model, its configuration, the processing_class e.g. tokenizer (if passed along to the [`Trainer`]) and a
                draft of a model card when the [`~Trainer.save_model`] method is called.
                - `"every_save"`: push the model, its configuration, the processing_class e.g. tokenizer (if passed along to the [`Trainer`])
                  and
                a draft of a model card each time there is a model save. The pushes are asynchronous to not block
                training, and in case the save are very frequent, a new push is only attempted if the previous one is
                finished. A last push is made with the final model at the end of training.
                - `"checkpoint"`: like `"every_save"` but the latest checkpoint is also pushed in a subfolder named
                last-checkpoint, allowing you to resume training easily with
                `trainer.train(resume_from_checkpoint="last-checkpoint")`.
                - `"all_checkpoints"`: like `"checkpoint"` but all checkpoints are pushed like they appear in the
                  output
                folder (so you will get one checkpoint folder per folder in your final repository)

            token (`str`, *optional*):
                The token to use to push the model to the Hub. Will default to the token in the cache folder obtained
                with `hf auth login`.
            private_repo (`bool`, *optional*, defaults to `False`):
                Whether to make the repo private. If `None` (default), the repo will be public unless the organization's default is private. This value is ignored if the repo already exists.
            always_push (`bool`, *optional*, defaults to `False`):
                Unless this is `True`, the `Trainer` will skip pushing a checkpoint when the previous push is not
                finished.
            revision (`str`, *optional*):
                The revision to use when pushing to the Hub. Can be a branch name, a tag, or a commit hash.

        Example:

        ```py
        >>> from transformers import TrainingArguments
