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 4 new columns ({'timestamp', 'period', 'mjd', 'id'}) and 4 missing columns ({'country', 'variability', 'name', 'mmt_id'}).

This happened while the csv dataset builder was generating data using

hf://datasets/kyselica/MMT_snapshot_csv/tracks.csv (at revision 390e12a61289bb86a3bc215db562efa3ed104e41)

Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://huggingface.co/docs/hub/datasets-manual-configuration#multiple-configurations)
