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 14 new columns ({'HIGH_PRICE', 'PRICE_CHANGE', 'CLOSE_PRICE', 'VOLUME', 'STOCK', 'MA_30', 'LOW_PRICE', 'RETURN', 'MA_7', 'MOMENTUM', 'TREND', 'VOLATILITY_7D', 'DATE', 'OPEN_PRICE'}) and 7 missing columns ({'Close', 'Volume', 'Scrip', 'Date', 'Low', 'High', 'Open'}).

This happened while the csv dataset builder was generating data using
