The dataset generation failed because of a cast error
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 5 new columns ({'2', 'hello', '4', '1', '3'}) and 5 missing columns ({'b', 'c', 'd', 'a', 'message'}).
This happened while the csv dataset builder was generating data using
hf://datasets/jianboy/demo-data/ex2.csv (at revision 27ad86b20b06fc060b4fc841cc6183ead8def0e5)
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)
