Data collators are objects that will form a batch by using a list of dataset elements as input. These elements are of
the same type as the elements of :obj:`train_dataset` or :obj:`eval_dataset`.
A data collator will default to :func:`transformers.data.data_collator.default_data_collator` if no `tokenizer` has
been provided. This is a function that takes a list of samples from a Dataset as input and collates them into a batch
of a dict-like object. The default collator performs special handling of potential keys:
To be able to build batches, data collators may apply some processing (like padding). Some of them (like
:class:`~transformers.DataCollatorForLanguageModeling`) also apply some random data augmentation (like random masking)
oin the formed batch.
- ``label``: handles a single value (int or float) per object
- ``label_ids``: handles a list of values per object
This function does not perform any preprocessing. An example of use can be found in glue and ner.
Examples of use can be found in the :doc:`example scripts <../examples>` or :doc:`example notebooks <../notebooks>`.
