取消部署模型

部署和预测后,您可手动取消部署模型,以避免产生更多费用。

通过取消部署模型,您可以避免产生更多的模型托管使用费用。 如需了解详情,请参阅价格页面

网页界面

  1. 打开 AutoML Vision Object Detection UI,然后在左侧导航栏中选择模型标签页(带有灯泡图标)以显示可用的模型。

    如需查看其他项目的模型,请从标题栏右上角的下拉列表中选择该项目。

  2. 选择要用于为图片添加标签的模型所对应的行。
  3. 选择标题栏正下方的测试和使用标签页。
  4. 从模型名称下方的横幅中选择移除部署,以打开取消部署选项窗口。

    取消部署弹出式菜单
  5. 选择删除部署以取消部署该模型。

    模型部署
  6. 模型取消部署完成后,您会收到电子邮件通知。

    “部署已完成”电子邮件

REST 和命令行

在使用下面的任何请求数据之前,请先进行以下替换:

  • project-id:您的 GCP 项目 ID。
  • model-id:您的模型的 ID(从创建模型时返回的响应中获取)。此 ID 是模型名称的最后一个元素。 例如:
    • 模型名称:projects/project-id/locations/location-id/models/IOD4412217016962778756
    • 模型 ID:IOD4412217016962778756

HTTP 方法和网址:

POST https://automl.googleapis.com/v1/projects/project-id/locations/us-central1/models/model-id:undeploy

如需发送请求,请选择以下方式之一:

curl

执行以下命令:

curl -X POST \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d "" \
https://automl.googleapis.com/v1/projects/project-id/locations/us-central1/models/model-id:undeploy

PowerShell

执行以下命令:

$cred = gcloud auth application-default print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
-Method POST `
-Headers $headers `
-Uri "https://automl.googleapis.com/v1/projects/project-id/locations/us-central1/models/model-id:undeploy" | Select-Object -Expand Content
您应该会收到包含部署操作 ID 的响应:
{
  "name": "projects/project-id/locations/us-central1/operations/operation-id",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.automl.v1.OperationMetadata",
    "createTime": "2019-08-07T22:19:50.828033Z",
    "updateTime": "2019-08-07T22:19:50.828033Z",
    "undeployModelDetails": {}
  }
}

您可以通过以下 HTTP 方法和网址获取操作的状态:

GET https://automl.googleapis.com/v1/projects/project-id/locations/us-central1/operations/operation-id

操作完成的状态将类似于以下内容:

{
  "name": "projects/project-id/locations/us-central1/operations/operation-id",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.automl.v1.OperationMetadata",
    "createTime": "2019-06-21T16:47:21.704674Z",
    "updateTime": "2019-06-21T17:01:00.802505Z",
    "deployModelDetails": {}
  },
  "done": true,
  "response": {
    "@type": "type.googleapis.com/google.protobuf.Empty"
  }
}
