The dataset generation failed because of a cast error
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 7 new columns ({'Coolant temp', 'Engine Condition', 'Fuel pressure', 'lub oil temp', 'Coolant pressure', 'Lub oil pressure', 'Engine rpm'}) and 12 missing columns ({'NumberOfFollowups', 'MonthlyIncome', 'PreferredPropertyStar', 'Age', 'CityTier', 'Passport', 'PitchSatisfactionScore', 'NumberOfChildrenVisiting', 'NumberOfTrips', 'DurationOfPitch', 'OwnCar', 'NumberOfPersonVisiting'}).

This happened while the csv dataset builder was generating data using

hf://datasets/vinaykumartv/tourism-project-data/engine.csv (at revision a3dd686dac1568b980d2c3a576927e5f71b9e719), ['hf://datasets/vinaykumartv/tourism-project-data@a3dd686dac1568b980d2c3a576927e5f71b9e719/Xtest.csv', 'hf://datasets/vinaykumartv/tourism-project-data@a3dd686dac1568b980d2c3a576927e5f71b9e719/Xtrain.csv', 'hf://datasets/vinaykumartv/tourism-project-data@a3dd686dac1568b980d2c3a576927e5f71b9e719/engine.csv', 'hf://datasets/vinaykumartv/tourism-project-data@a3dd686dac1568b980d2c3a576927e5f71b9e719/tourism.csv', 'hf://datasets/vinaykumartv/tourism-project-data@a3dd686dac1568b980d2c3a576927e5f71b9e719/ytest.csv', 'hf://datasets/vinaykumartv/tourism-project-data@a3dd686dac1568b980d2c3a576927e5f71b9e719/ytrain.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)
