运行Azure数据工厂管道时出错。未找到链接服务参考

Question

我在创建Azure机器学习批处理执行活动以执行评分ML实验时面临以下问题。请帮忙：

如果需要任何其他相关信息，请与我们联系。我是新手，请帮助

1. 创建AzureML链接服务，如下所示：

   {
   "name": "PredictionAzureML",
   "properties": {
   "typeProperties": {
   "mlEndpoint": "https://ussouthcentral.services.azureml.net/workspaces/xxxxx/jobs",
   "apiKey": "xxxxxxxx=="
   },
   "type": "AzureML"
   }
   }
   

2. 创建的管道如下：

   {
   "name": "pipeline1",
   "properties": {
   "description": "use AzureML model",
   "activities": [
   {
   "name": "MLActivity",
   "description": "description",
   "type": "AzureMLBatchExecution",
   "policy": {
   "timeout": "02:00:00",
   "retry": 1,
   "retryIntervalInSeconds": 30
   },
   "typeProperties": {
   "webServiceInput": "PredictionInputDataset",
   "webServiceOutputs": {
   "output1": "PredictionOutputDataset"
   }
   },
   "inputs": [
   {
   "name": "PredictionInputDataset"
   }
   ],
   "outputs": [
   {
   "name": "PredictionOutputDataset"
   }
   ],
   "linkedServiceName": "PredictionAzureML"
   }
   ]
   }
   }
   

3. 获取以下错误：

    {
   "errorCode": "2109",
   "message": "'linkedservicereference' with reference name 'PredictionAzureML' can't be found.",
   "failureType": "UserError",
   "target": "MLActivity"
   }
   

Answer 1

请使用＆＃34;触发＆＃34;而不是＆＃34; Debug＆＃34;在UX中。在点击＆＃34; Trigger＆＃34;之前，您需要首先发布您的管道。按钮。 请按照this doc更新您的有效负载。它应该如下所示。 { "name": "AzureMLExecutionActivityTemplate", "description": "description", "type": "AzureMLBatchExecution", "linkedServiceName": { "referenceName": "AzureMLLinkedService", "type": "LinkedServiceReference" }, "typeProperties": { "webServiceInputs": { "<web service input name 1>": { "LinkedServiceName":{ "referenceName": "AzureStorageLinkedService1", "type": "LinkedServiceReference" }, "FilePath":"path1" }, "<web service input name 2>": { "LinkedServiceName":{ "referenceName": "AzureStorageLinkedService1", "type": "LinkedServiceReference" }, "FilePath":"path2" }
}, "webServiceOutputs": { "<web service output name 1>": { "LinkedServiceName":{ "referenceName": "AzureStorageLinkedService2", "type": "LinkedServiceReference"
}, "FilePath":"path3" }, "<web service output name 2>": { "LinkedServiceName":{ "referenceName": "AzureStorageLinkedService2", "type": "LinkedServiceReference"
}, "FilePath":"path4" }
}, "globalParameters": { "<Parameter 1 Name>": "<parameter value>", "<parameter 2 name>": "<parameter 2 value>" } } }

Answer 2

我在Data Factory v2中使用了这个，所以如果你使用v1，请道歉。

尝试将linkedServiceName作为对象放在typeProperties之外的JSON中，并使用以下结构：

"linkedServiceName": {
  "referenceName": "PredictionAzureML",
  "type": "LinkedServiceReference"
}

希望有所帮助！
