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 ({'texto_kanoe', 'traducao_pt', 'fk_id_bibliografia', 'id_frase', 'fk_id_palavra', 'contexto_uso', 'fk_id_significado'}) and 7 missing columns ({'id_fonte', 'tipo', 'arquivo_ref', 'titulo', 'ano', 'autores', 'notas'}).
