python - 错误无效输入数据类型 : Input of type 'Unknown' is not supported in azure (azureml. train.automl)

Question

我有一个 pandas 的 DataFrame 创建者:

TB_HISTORICO_MODELO = pd.read_sql("""select DAT_INICIO_SEMANA_PLAN
,COD_NEGOCIO
,VENDA
,LUCRO
,MODULADO
,RUPTURA
,QTD_ESTOQUE_MEDIO
,PECAS from TB""", cursor)

TB_HISTORICO_MODELO["DAT_INICIO_SEMANA_PLAN"] = pd.to_datetime(TB_HISTORICO_MODELO["DAT_INICIO_SEMANA_PLAN"])

dataset = TB_HISTORICO_MODELO[TB_HISTORICO_MODELO['COD_NEGOCIO']=='A101'].drop(columns=['COD_NEGOCIO']) .reset_index(drop=True)

一切看起来都很正确。

>>> dataset.dtypes
DAT_INICIO_SEMANA_PLAN    datetime64[ns]
VENDA                            float64
LUCRO                            float64
MODULADO                           int64
RUPTURA                            int64
QTD_ESTOQUE_MEDIO                  int64
PECAS                            float64
dtype: object

但是当我朗诵这个时:

#%% Create the AutoML Config file and run the experiment on Azure

from azureml.train.automl import AutoMLConfig

time_series_settings = {
   'time_column_name': 'DAT_INICIO_SEMANA_PLAN',

   'country_or_region': 'BR',
   'target_lags': 'auto'
}

automl_config = AutoMLConfig(task='forecasting',
                            primary_metric='normalized_root_mean_squared_error',
                            blocked_models=['ExtremeRandomTrees'],

                            label_column_name='VENDA',
                            compute_target = compute_cluster,
                            enable_early_stopping=True,

                            # max_cores_per_iteration=-1,
                            verbosity=logging.INFO,
                            **time_series_settings)

remote_run = Experimento.submit(automl_config, show_output=True)

我收到消息了

>>> remote_run = Experimento.submit(automl_config, show_output=True)

                }
            }
        }
    }
}

哪里错了？

Configure AutoML Doc说:

For remote experiments, training data must be accessible from the remote compute. AutoML only accepts Azure Machine Learning TabularDatasets when working on a remote compute.

看起来您的dataset对象是一个Pandas DataFrame，而实际上它应该是一个Azure ML Dataset。查看this doc关于创建数据集。
