读取数据集报错

当读取数据的时候，遇到了以下问题：

Generating train split: 112142 examples [00:00, 160735.47 examples/s]

because column names don't match

During handling of the above exception, another exception occurred:

datasets.exceptions.DatasetGenerationCastError: An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 1 new columns ({'type'})

This happened while the json dataset builder was generating data using

/home/lj/datasets/rolebench/rolebench-eng/instruction-generalization/role_specific/train.jsonl

Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)
