    "To instantiate a `ORTTrainer`, we will need to define two more things. The most important is the [`ORTTrainingArguments`](https://huggingface.co/docs/optimum/onnxruntime/trainer#optimum.onnxruntime.ORTTrainingArguments), which is a class that contains all the attributes to customize the training. You can also use `TrainingArguments` in Transformers, but `ORTTrainingArguments` enables more optimized features of ONNX Runtime. It requires one folder name, which will be used to save the checkpoints of the model, and all other arguments are optional:"

This is because we will use it once last time to make all the samples we gather the same length by applying padding, which requires knowing the model's preferences regarding padding (to the left or right? with which token?). The `tokenizer` has a pad method that will do all of this right for us, and the `ORTTrainer` will use it.
