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。
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)
-
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。
打开 Amazon Lookout for Vision 控制台,网址为 https://console.aws.amazon.com/lookoutvision/。
选择开始使用。
在左侧导航窗格中,选择项目。
在项目资源页面上,选择包含要停止的运行中模型的项目。
在模型部分,选择要停止的模型。
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。
在 Amazon CLI 命令下,复制用于调用 stop-model
的 AWS CLI 命令。
-
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。
在控制台,选择左侧导航页面中的模型。
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)
-
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。
使用以下示例代码停止正在运行的模型。
- CLI
-
更改以下值:
aws lookoutvision stop-model --project-name "project name
"\
--model-version model version
\
--profile lookoutvision-access
- Python
