Instead of `List[float]` you can have tensors (numpy arrays, PyTorch tensors or TensorFlow tensors),
see the note above for the return type.
padding (`bool`, `str` or [`~utils.PaddingStrategy`], *optional*, defaults to `True`):
Select a strategy to pad the returned sequences (according to the model's padding side and padding
index) among:
| 177 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/feature_extraction_sequence_utils.py
|
- `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single
sequence if provided).
- `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum
acceptable input length for the model if that argument is not provided.
- `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different
lengths).
max_length (`int`, *optional*):
Maximum length of the returned list and optionally padding length (see above).
truncation (`bool`):
Activates truncation to cut input sequences longer than `max_length` to `max_length`.
pad_to_multiple_of (`int`, *optional*):
If set will pad the sequence to a multiple of the provided value.

This is especially useful to enable the use of Tensor Cores on NVIDIA hardware with compute capability
`>= 7.5` (Volta), or on TPUs which benefit from having sequence lengths be a multiple of 128.
return_attention_mask (`bool`, *optional*):
Whether to return the attention mask. If left to the default, will return the attention mask according
to the specific feature_extractor's default.
[What are attention masks?](../glossary#attention-mask)
return_tensors (`str` or [`~utils.TensorType`], *optional*):
If set, will return tensors instead of list of python integers. Acceptable values are:
| 177 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/feature_extraction_sequence_utils.py
|
- `'tf'`: Return TensorFlow `tf.constant` objects.
- `'pt'`: Return PyTorch `torch.Tensor` objects.
- `'np'`: Return Numpy `np.ndarray` objects.

Parameters:
output_dir (`str`):
The output directory where the model predictions and checkpoints will be written.
overwrite_output_dir (`bool`, *optional*, defaults to `False`):
If `True`, overwrite the content of the output directory. Use this to continue training if `output_dir`
points to a checkpoint directory.
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
| 179 |

training/evaluation scripts instead. See the [example
scripts](https://github.com/huggingface/transformers/tree/main/examples) for more details.
do_predict (`bool`, *optional*, defaults to `False`):
Whether to run predictions on the test set 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.
eval_strategy (`str` or [`~trainer_utils.IntervalStrategy`], *optional*, defaults to `"no"`):
The evaluation strategy to adopt during training. Possible values are:
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
- `"no"`: No evaluation is done during training.
- `"steps"`: Evaluation is done (and logged) every `eval_steps`.
- `"epoch"`: Evaluation is done at the end of each epoch.
prediction_loss_only (`bool`, *optional*, defaults to `False`):
When performing evaluation and generating predictions, only returns the loss.
per_device_train_batch_size (`int`, *optional*, defaults to 8):
The batch size per GPU/XPU/TPU/MPS/NPU core/CPU for training.
per_device_eval_batch_size (`int`, *optional*, defaults to 8):
The batch size per GPU/XPU/TPU/MPS/NPU core/CPU for evaluation.
gradient_accumulation_steps (`int`, *optional*, defaults to 1):

<Tip warning={true}>
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
When using gradient accumulation, one step is counted as one step with backward pass. Therefore, logging,
evaluation, save will be conducted every `gradient_accumulation_steps * xxx_step` training examples.
</Tip>
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 GPU/NPU/TPU before being moved to the CPU (faster but
requires more memory).
eval_delay (`float`, *optional*):
Number of epochs or steps to wait for before the first evaluation can be performed, depending on the
eval_strategy.
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.
<Tip>

|
the last epoch before stopping training).
max_steps (`int`, *optional*, defaults to -1):
If set to a positive number, the total number of training steps to perform. Overrides `num_train_epochs`.
For a finite dataset, training is reiterated through the dataset (if all data is exhausted) until
`max_steps` is reached.
lr_scheduler_type (`str` or [`SchedulerType`], *optional*, defaults to `"linear"`):
The scheduler type to use. See the documentation of [`SchedulerType`] for all possible values.
lr_scheduler_kwargs ('dict', *optional*, defaults to {}):
The extra arguments for the lr_scheduler. See the documentation of each scheduler for possible values.
warmup_ratio (`float`, *optional*, defaults to 0.0):
Ratio of total training steps used for a linear warmup from 0 to `learning_rate`.
warmup_steps (`int`, *optional*, defaults to 0):

/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
Number of steps used for a linear warmup from 0 to `learning_rate`. Overrides any effect of `warmup_ratio`.
log_level (`str`, *optional*, defaults to `passive`):
Logger log level to use on the main process. Possible choices are the log levels as strings: 'debug',
'info', 'warning', 'error' and 'critical', plus a 'passive' level which doesn't set anything and keeps the
current log level for the Transformers library (which will be `"warning"` by default).
log_level_replica (`str`, *optional*, defaults to `"warning"`):
Logger log level to use on replicas. Same choices as `log_level`"
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.

/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
*output_dir/runs/**CURRENT_DATETIME_HOSTNAME***.
logging_strategy (`str` or [`~trainer_utils.IntervalStrategy`], *optional*, defaults to `"steps"`):
The logging strategy to adopt during training. Possible values are:
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
- `"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_first_step (`bool`, *optional*, defaults to `False`):
Whether to log the first `global_step` or not.
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_nan_inf_filter (`bool`, *optional*, defaults to `True`):
Whether to filter `nan` and `inf` losses for logging. If set to `True` the loss of every step that is `nan`
or `inf` is filtered and the average loss of the current logging window is taken instead.
<Tip>
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
`logging_nan_inf_filter` only influences the logging of loss values, it does not change the behavior the
gradient is computed or applied to the model.
</Tip>
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.

very end of training, always.
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_total_limit (`int`, *optional*):
If a value is passed, will limit the total amount of checkpoints. Deletes the older checkpoints in
`output_dir`. When `load_best_model_at_end` is enabled, the "best" checkpoint according to
`metric_for_best_model` will always be retained in addition to the most recent ones. For example, for
`save_total_limit=5` and `load_best_model_at_end`, the four last checkpoints will always be retained
| 179 |

The timeout for `torch.distributed.init_process_group` calls, used to avoid GPU socket timeouts when
performing slow operations in distributed runnings. Please refer the [PyTorch documentation]
(https://pytorch.org/docs/stable/distributed.html#torch.distributed.init_process_group) for more
information.
use_mps_device (`bool`, *optional*, defaults to `False`):
This argument is deprecated.`mps` device will be used if it is available similar to `cuda` device.
torch_compile (`bool`, *optional*, defaults to `False`):
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
Whether or not to compile the model using PyTorch 2.0
[`torch.compile`](https://pytorch.org/get-started/pytorch-2.0/).
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
This will use the best defaults for the [`torch.compile`
API](https://pytorch.org/docs/stable/generated/torch.compile.html?highlight=torch+compile#torch.compile).
You can customize the defaults with the argument `torch_compile_backend` and `torch_compile_mode` but we
don't guarantee any of them will work as the support is progressively rolled in in PyTorch.
This flag and the whole compile API is experimental and subject to change in future releases.
torch_compile_backend (`str`, *optional*):
The backend to use in `torch.compile`. If set to any value, `torch_compile` will be set to `True`.
Refer to the PyTorch doc for possible values and note that they may change across PyTorch versions.
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
This flag is experimental and subject to change in future releases.
torch_compile_mode (`str`, *optional*):
The mode to use in `torch.compile`. If set to any value, `torch_compile` will be set to `True`.
Refer to the PyTorch doc for possible values and note that they may change across PyTorch versions.
This flag is experimental and subject to change in future releases.
split_batches (`bool`, *optional*):
Whether or not the accelerator should split the batches yielded by the dataloaders across the devices
during distributed training. If
set to `True`, the actual batch size used will be the same on any kind of distributed processes, but it
must be a
round multiple of the number of processes you are using (such as GPUs).
include_tokens_per_second (`bool`, *optional*):
Whether or not to compute the number of tokens per second per device for training speed metrics.
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
This will iterate over the entire training dataloader once beforehand,
and will slow down the entire process.
include_num_input_tokens_seen (`bool`, *optional*):
Whether or not to track the number of input tokens seen throughout training.
May be slower in distributed training as gather operations must be called.
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
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://arxiv.org/abs/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].
optim_target_modules (`Union[str, List[str]]`, *optional*):
The target modules to optimize, i.e. the module names that you would like to train, right now this is used only for GaLore algorithm
https://arxiv.org/abs/2403.03507
See: https://github.com/jiaweizzhao/GaLore for more details. You need to make sure to pass a valid GaloRe
optimizer, e.g. one of: "galore_adamw", "galore_adamw_8bit", "galore_adafactor" and make sure that the target modules are `nn.Linear` modules
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
only.
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
batch_eval_metrics (`Optional[bool]`, 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.
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.
| 179 |
/Users/nielsrogge/Documents/python_projecten/transformers/src/transformers/training_args.py
|
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.
use_liger_kernel (`bool`, *optional*, defaults to `False`):
Whether enable [Liger](https://github.com/linkedin/Liger-Kernel) Kernel for LLM model training.
It can effectively increase multi-GPU training throughput by ~20% and reduces memory usage by ~60%, works out of the box with
flash attention, PyTorch FSDP, and Microsoft DeepSpeed. Currently, it supports llama, mistral, mixtral and gemma models.
