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 2 new columns ({'unique_id', 'Chemical Family'})

This happened while the csv dataset builder was generating data using

hf://datasets/suchonaakter/NaCAM-Atlas/gen2_voltage_ge_3_with_ids.csv (at revision 1c5ae16bdd9b1e0a0ddf4d7df71098735824c6ab), ['hf://datasets/suchonaakter/NaCAM-Atlas@1c5ae16bdd9b1e0a0ddf4d7df71098735824c6ab/gen2_final_voltage_predictions.csv', 'hf://datasets/suchonaakter/NaCAM-Atlas@1c5ae16bdd9b1e0a0ddf4d7df71098735824c6ab/gen2_voltage_ge_3_with_ids.csv']

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)
