错误 InvalidInputDatatype：天蓝色不支持 'Unknown' 类型的输入 (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)

一切看起来都不错。

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

但是当我朗姆酒时：

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

from azureml.train.automl import AutoMLConfig

                            **time_series_settings)

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

我收到消息

                }
            }
        }
    }
}

哪里错了？

Answer 1

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 创建数据集。
