Need to add a Loop here?

[talkingwallace]

In data.py, process_text2text_datasets

‘’‘python
def process_text2text_datasets(raw_datasets, args, tokenizer, accelerator):
task = task_dict[args.dataset_name]

column_names = raw_datasets["train"].column_names

def tokenize_function(examples):
    context = task.get_context(examples)
    target = task.get_target(examples)

    context = tokenizer(context)
    target = tokenizer(target)

    
    # if context is ending with special token, remove it
    if len(context['input_ids'][0]) > 0 and context['input_ids'][0][-1] in tokenizer.all_special_ids:
        print('1')
        context['input_ids'] = [i[:-1] for i in context['input_ids']]
        context['attention_mask'] = [a[:-1]
                                     for a in context['attention_mask']]

    # if target is starting with special token, remove it
    if len(target['input_ids'][0]) > 0 and target['input_ids'][0][0] in tokenizer.all_special_ids:
        print('2')
        target['input_ids'] = [i[1:] for i in target['input_ids']]
        target['attention_mask'] = [a[1:]
                                    for a in target['attention_mask']]

Do we need to add an outer loop for the special token removing codes, since "example" is a batch of samples?
