【问题描述】：

我使用clist=ComputeTarget.list(workspace=ws) 在工作区中查找计算目标列表，如下所示：

[{
   "id": "/subscriptions/94e14ad4-bf97-47e8-aae0-f9b85a7befa8/resourceGroups/.../providers/Microsoft.MachineLearningServices/workspaces/.../computes/std-ds3-v2",
   "name": "std-ds3-v2",
   "location": "southcentralus",
   "tags": null,
   "properties": {
     "description": null,
     "computeType": "ComputeInstance",
     "computeLocation": "southcentralus",
     "resourceId": null,
     "provisioningErrors": null,
     "provisioningState": "Succeeded",
     "properties": {
       "vmSize": "STANDARD_DS3_V2",
       "applications": [
         {
           "displayName": "Jupyter",
           "endpointUri": "https://std-ds3-v2.southcentralus.instances.azureml.ms"
         },
         {
           "displayName": "Jupyter Lab",
           "endpointUri": "https://std-ds3-v2.southcentralus.instances.azureml.ms/lab"
         },
         {
           "displayName": "RStudio",
           "endpointUri": "https://std-ds3-v2-8787.southcentralus.instances.azureml.ms"
         }
       ],
     ...
     ...
   }
 }]

clist 对象看起来像一个字典元素列表。我想动态检索字典元素"name": "std-ds3-v2"，所以我尝试了clist[0]['name']，但得到了这个错误：

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-101-df855b4d0107> in <module>
----> 1 clist[0]['name']

TypeError: 'ComputeInstance' object is not subscriptable

如何从clist 对象中检索"name": "std-ds3-v2"？

谢谢。

【解决方案1】：

>>> [x.name for x in ComputeTarget.list(workspace=ws)]
['aks-cluster', 'aks-a2-cluster', 'cpu-compute']

>>> list(ws.compute_targets.keys())
['aks-cluster', 'aks-a2-cluster', 'cpu-compute']
