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 12 new columns ({'img_id', 'answer', 'answer_type', 'qid', 'img_name', 'content_type', 'modality', 'base_type', 'triple', 'location', 'q_lang', 'question'}) and 2 missing columns ({'image', 'conversations'}).

This happened while the json dataset builder was generating data using

hf://datasets/WOOJYE/ccpo_slake/train_lung.json (at revision 51b26dd4a918434f6f638a18f62ae2e2eec7cdf8), ['hf://datasets/WOOJYE/ccpo_slake@51b26dd4a918434f6f638a18f62ae2e2eec7cdf8/train_data_slake.json', 'hf://datasets/WOOJYE/ccpo_slake@51b26dd4a918434f6f638a18f62ae2e2eec7cdf8/train_lung.json'], ['hf://datasets/WOOJYE/ccpo_slake@51b26dd4a918434f6f638a18f62ae2e2eec7cdf8/train_data_slake.json', 'hf://datasets/WOOJYE/ccpo_slake@51b26dd4a918434f6f638a18f62ae2e2eec7cdf8/train_lung.json']

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)
