def __call__(self, batch):
    lengths = [len(instance["input_ids"]) for instance in batch]
    batch_max_len = max(lengths)

    input_ids_batch, labels_batch = [], []
    for instance in batch:
        input_ids = instance["input_ids"]
        labels = instance["labels"]

        padding_len = batch_max_len - len(input_ids)
        input_ids = input_ids + [self.pad_token_id] * padding_len
        labels = labels + [-100] * padding_len

        input_ids_batch.append(input_ids)
        labels_batch.append(labels)

   input_ids不应该在左面填充pad吗
