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 3 new columns ({'Lending Fee', 'Lending Volume', 'Date'}) and 4 missing columns ({'Trading Value', 'Trading Volume.1', 'Trading Volume', 'Trading Value.1'}).

This happened while the csv dataset builder was generating data using

hf://datasets/johnmatters/Data/dayTrading-BFIF8U/BFIF8U_20150501.csv (at revision 74fedd48bef26b96a11540753bda24bd8c6eff29)

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)
