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 ({'book', 'user_id', 'rating', 'user'}) and 1 missing columns ({'title'}).

This happened while the csv dataset builder was generating data using

hf://datasets/hqasmei/collaborative-filtering-dataset/filtered_data.csv (at revision 5a7d4e2cc6481ebd711f42b0c0397d1fc3d07a15)

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)
