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 8 new columns ({'has_electricity', 'site_id', 'site_name', 'road_number', 'site_type', 'ely_region', 'winter_maintenance', 'parking_capacity'}) and 9 missing columns ({'non_stop_express_bus', 'stop_id', 'municipality_code', 'special_needs', 'virtual_stop', 'local_bus', 'reachability', 'stop_name', 'express_bus'}).

This happened while the csv dataset builder was generating data using

hf://datasets/data-sci-project/road-attributes/service_areas.csv (at revision f18915d9bcb1c4bca12803a74df8ba4f5977fe8a), ['hf://datasets/data-sci-project/road-attributes@f18915d9bcb1c4bca12803a74df8ba4f5977fe8a/public_transport_stops.csv', 'hf://datasets/data-sci-project/road-attributes@f18915d9bcb1c4bca12803a74df8ba4f5977fe8a/service_areas.csv', 'hf://datasets/data-sci-project/road-attributes@f18915d9bcb1c4bca12803a74df8ba4f5977fe8a/speed_limits.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)
