DescribePredictor

注意

此操作仅对使用创建的传统预测变量有效 CreatePredictor。如果您不使用传统预测变量，请使用DescribeAutoPredictor。

描述使用该CreatePredictor运算创建的预测变量。

除了列出CreatePredictor请求中提供的属性外，此操作还列出了以下属性：

DatasetImportJobArns-用于导入训练数据的数据集导入作业。
AutoMLAlgorithmArns-如果执行 AutoML，则为已评估的算法。
CreationTime
LastModificationTime
Status
Message-如果发生错误，则为有关错误的信息。

请求语法


{
   "PredictorArn": "string"
}

请求参数

请求接受采用 JSON 格式的以下数据。

PredictorArn

您要获取相关信息的预测变量的 Amazon Resource Name (ARN)。

类型：字符串

长度限制：最大长度为 256。

模式：arn:([a-z\d-]+):forecast:.*:.*:.+

必需：是
