Error code:   DatasetGenerationCastError
Exception:    DatasetGenerationCastError
Message:      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 ({'stats'}) and 2 missing columns ({'length', 'tasks'}).

This happened while the json dataset builder was generating data using

hf://datasets/HeyuGuo/grasp_2_cam_3_test/meta/episodes_stats.jsonl (at revision 434a991b2054a855eb9c040af8822d69a7e5f755)

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)
