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 8 new columns ({'monthly_spend', 'churn', 'customer_id', 'last_login', 'signup_date', 'plan', 'tenure_months', 'support_tickets'}) and 17 missing columns ({'CALC', 'Height', 'NCP', 'SCC', 'Gender', 'FAF', 'NObeyesdad', 'Weight', 'FCVC', 'TUE', 'MTRANS', 'CAEC', 'SMOKE', 'family_history_with_overweight', 'FAVC', 'Age', 'CH2O'}).
This happened while the csv dataset builder was generating data using
