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 missing columns ({'certified '})

This happened while the csv dataset builder was generating data using

hf://datasets/VerisimilitudeX/edX/edx_test.csv (at revision c747badede350def34047bfc23d01f6e4d119c2b)

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)
