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 ({'Expiry', 'Vols', 'Strike'}) and 2 missing columns ({'Swap Rate', 'Start Date'}).

This happened while the csv dataset builder was generating data using

hf://datasets/Carzit/UBS-RAN/market-data-swaption-vols.csv (at revision 74ab6fdb0f23a87edebb155013b074ad410864c8)

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)
