停止您的 Amazon Lookout for Vision 模型

要停止正在运行的模型,您可以调用 StopModel 操作并传递以下项:

  • 项目:包含要停止的模型的项目的名称。

  • ModelVersion:要停止的模型版本。

Amazon Lookout for Vision 控制台提供了示例代码,可用于停止模型。

注意

您需要按照模型的运行时间量付费。

停止您的模型(控制台)

执行以下过程中的步骤,可以使用控制台停止您的模型。

停止您的模型(控制台)
  1. 安装并配置 AWS CLI 和 AWS SDK(如果尚未如此)。有关更多信息,请参阅 步骤 4:设置 AWS CLI 和 AWS 软件开发工具包

  2. 打开 Amazon Lookout for Vision 控制台,网址为 https://console.aws.amazon.com/lookoutvision/

  3. 选择开始使用

  4. 在左侧导航窗格中,选择项目

  5. 项目资源页面上,选择包含要停止的运行中模型的项目。

  6. 模型部分,选择要停止的模型。

  7. 在模型的详细信息页面上,选择使用模型,然后选择将 API 集成到云

  8. Amazon CLI 命令下,复制用于调用 stop-model 的 AWS CLI 命令。

  9. 在命令提示符处,输入您在上一步中复制的 stop-model 命令。如果您使用 lookoutvision 配置文件来获取凭证,请添加 --profile lookoutvision-access 参数。

  10. 在控制台,选择左侧导航页面中的模型

  11. 查看状态列以了解模型的当前状态。当状态列的值为训练完成时,表示模型已停止。

停止您的 Amazon Lookout for Vision 模型 (SDK)

您可以通过调用 StopModel 操作来停止模型。

模型可能需要一段时间才能停止。要检查当前状态,请使用 DescribeModel

停止您的模型 (SDK)
  1. 安装并配置 AWS CLI 和 AWS SDK(如果尚未如此)。有关更多信息,请参阅 步骤 4:设置 AWS CLI 和 AWS 软件开发工具包

  2. 使用以下示例代码停止正在运行的模型。

    CLI

    更改以下值:

    • project-name 更改为包含要停止的模型的项目的名称。

    • model-version 更改为要停止的模型版本。

    aws lookoutvision stop-model --project-name "project name"\ --model-version model version \ --profile lookoutvision-access
