The TrainingArguments class has arguments do\_train, do\_eval, do\_predict that “are not directly used by the Trainer class”.  
They are allegedly intended to be used by my training scripts. But how? If I write a training script to train a model it will train the model. Why do I need an extra argument for that?  
The examples link does not point to any specific example with explanation.
