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 new columns ({'description'}) and 23 missing columns ({'band_gap', 'formation_energy_per_atom', 'density', 'chemsys', 'nsites', 'symmetry', 'point_group', 'point_group_order', 'lattice_beta', 'lattice_a', 'is_centrosymmetric', 'lattice_c', 'lattice_alpha', 'ordering', 'nelements', 'lattice_b', 'bravais_lattice', 'density_atomic', 'formula_pretty', 'total_magnetization', 'num_magnetic_sites', 'lattice_gamma', 'space_group_number'}).

This happened while the csv dataset builder was generating data using

hf://datasets/Godseye1311/alignn-band-gap/text_data.csv (at revision 7bb6f33a9634e21d3cf3a5839377d977d1e1b3bb), ['hf://datasets/Godseye1311/alignn-band-gap@7bb6f33a9634e21d3cf3a5839377d977d1e1b3bb/materials_tabular.csv', 'hf://datasets/Godseye1311/alignn-band-gap@7bb6f33a9634e21d3cf3a5839377d977d1e1b3bb/text_data.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)
