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 3 new columns ({'yy-3', 'yy-2', 'yy-1'}) and 3 missing columns ({'xx-3', 'xx-2', 'xx-1'}).

This happened while the csv dataset builder was generating data using

hf://datasets/aamnaa123/cfd-surroagte-data/yy_combined.csv (at revision c3583a94ed5e09cccb4ecf5f65550675d3bd9ee8), ['hf://datasets/aamnaa123/cfd-surroagte-data@c3583a94ed5e09cccb4ecf5f65550675d3bd9ee8/xx_combined.csv', 'hf://datasets/aamnaa123/cfd-surroagte-data@c3583a94ed5e09cccb4ecf5f65550675d3bd9ee8/yy_combined.csv', 'hf://datasets/aamnaa123/cfd-surroagte-data@c3583a94ed5e09cccb4ecf5f65550675d3bd9ee8/zz_combined.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)
