管理模型

使用集合让一切井井有条 根据您的偏好保存内容并对其进行分类。

本页面介绍如何使用 AutoML Tables 部署、取消部署、列出、删除和获取自定义模型的相关信息。

如需了解如何训练新模型,请参阅训练模型

部署模型

训练模型后,您必须先部署模型,然后才能使用该模型请求在线预测。可以从未部署的模型请求批量预测。

部署模型会产生费用。如需了解详情,请参阅价格页面。

控制台

  1. 转到 Google Cloud Console 中的 AutoML Tables 页面。

    转到 AutoML Tables 页面

  2. 在左侧导航窗格中,选择模型标签页,然后选择区域

  3. 在要部署的模型的更多操作菜单中,点击部署模型

    部署的“更多操作”菜单

REST

使用 models.deploy 方法部署模型。

在使用任何请求数据之前,请先进行以下替换:

  • endpoint:全球位置为 automl.googleapis.com,欧盟地区为 eu-automl.googleapis.com
  • project-id:您的 Google Cloud 项目 ID。
  • location:资源的位置:全球位置为 us-central1,欧盟位置为 eu
  • model-id:要部署的模型的 ID。例如,TBL543

HTTP 方法和网址:

POST https://endpoint/v1beta1/projects/project-id/locations/location/models/model-id:deploy

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 print-access-token)" \
-H "x-goog-user-project: project-id" \
-H "Content-Type: application/json; charset=utf-8" \
-d "" \
"https://endpoint/v1beta1/projects/project-id/locations/location/models/model-id:deploy"

PowerShell

执行以下命令:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "project-id" }

Invoke-WebRequest `
-Method POST `
-Headers $headers `
-Uri "https://endpoint/v1beta1/projects/project-id/locations/location/models/model-id:deploy" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应:

AutoML Tables 的客户端库包含其他 Python 方法,这些方法使用 AutoML Tables API 进行简化。这些方法按名称而不是 ID 来引用数据集和模型。您的数据集和模型的名称必须是唯一的。如需了解详情,请参阅客户端参考

删除模型

删除模型会将该模型从项目中永久移除。

控制台

  1. AutoML Tables 界面中,点击左侧导航菜单中的模型标签页并选择区域,以显示该区域的可用模型的列表。

  2. 点击待删除行最右侧的三点状菜单,然后选择删除模型

  3. 在确认对话框中点击删除

REST

您可以使用 models.delete 方法删除模型。

在使用任何请求数据之前,请先进行以下替换:

  • endpoint:全球位置为 automl.googleapis.com,欧盟地区为 eu-automl.googleapis.com
  • project-id:您的 Google Cloud 项目 ID。
  • location:资源的位置:全球位置为 us-central1,欧盟位置为 eu
  • model-id:要删除的模型的 ID。例如,TBL543

HTTP 方法和网址:

DELETE https://endpoint/v1beta1/projects/project-id/locations/location/models/model-id

如需发送请求,请选择以下方式之一:

curl

执行以下命令:

curl -X DELETE \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "x-goog-user-project: project-id" \
"https://endpoint/v1beta1/projects/project-id/locations/location/models/model-id"

PowerShell

执行以下命令:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred"; "x-goog-user-project" = "project-id" }

Invoke-WebRequest `
-Method DELETE `
-Headers $headers `
-Uri "https://endpoint/v1beta1/projects/project-id/locations/location/models/model-id" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应:

{
  "name": "projects/29452381/locations/us-central1/operations/TBL543",
  "metadata": {
    "@type": "type.googleapis.com/google.cloud.automl.v1beta1.OperationMetadata",
    "createTime": "2019-12-26T17:19:50.684850Z",
    "updateTime": "2019-12-26T17:19:50.684850Z",
    "deleteDetails": {},
    "worksOn": [
      "projects/29452381/locations/us-central1/models/TBL543"
    ],
    "state": "DONE"
  },
  "done": true,
  "response": {
    "@type": "type.googleapis.com/google.protobuf.Empty"
  }
}

删除模型是一项长时间运行的操作。您可以轮询操作状态或等待操作返回。了解详情
