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 ({'CameraID', 'Lat', 'ImageLink', 'Lon'}) and 7 missing columns ({'StartPoint', 'EstTimeMin', 'Direction', 'Expressway', 'FarEndPoint', 'EndPoint', 'dow'}).
