# 使用 Step Functions 创建和管理亚马逊 SageMaker AI 任务
学习如何使用 Step Functions 在 SageMaker AI 上创建和管理作业。本页列出了支持的 SageMaker AI API 操作，并提供了创建 SageMaker AI 转换、训练、标记和处理任务的示例`Task`状态。
要了解如何在 Step Functions 中与AWS服务集成，请参阅[集成 服务](integrate-services.md)和[在 Step Functions 中将参数传递给服务 API](connect-parameters.md)。
**优化的 A SageMaker I 集成的主要功能**
支持[运行作业 (.sync)](connect-to-resource.md#connect-sync) 集成模式。
没有针对 [请求响应](connect-to-resource.md#connect-default) 集成模式的特定优化。
不支持[等待具有任务令牌的回调](connect-to-resource.md#connect-wait-token)集成模式。

**注意**
AWS Step Functions不会自动为创建策略`CreateTransformJob`。您必须将内联策略附加到创建的角色。有关更多信息，请参阅此示例 IAM 策略：[`CreateTrainingJob`](#sagemaker-iam-createtrainingjob)。

## 用于调用 Amazon A SageMaker I 的 IAM 政策
以下示例模板展示了如何根据状态机定义中的资源AWS Step Functions生成 IAM 策略。有关更多信息，请参阅[Step Functions 如何为集成服务生成 IAM 策略](service-integration-iam-templates.md)和[探索 Step Functions 中的服务集成模式](connect-to-resource.md)。
**注意**
对于这些示例，`roleArn`请参阅 IAM 角色的 Amazon 资源名称 (ARN)，A SageMaker I 使用该角色访问模型工件和 docker 镜像，以便在 ML 计算实例上部署，或用于批量转换任务。有关更多信息，请参阅 [Amazon SageMaker 角色](https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-roles.html)。
