# 使用 SageMaker API 更新 SageMaker HyperPod 集群的训练计划，或者 Amazon CLI
<a name="use-training-plan-for-hyperpod-update-using-api-cli-sdk"></a>

您可以使用`update-cluster` Amazon CLI 命令更新现有集群的实例组，从而添加、更新或删除训练计划。以下示例说明了如何更新集 SageMaker HyperPod 群并为实例组提供新的训练计划。

```
# Update a cluster
aws sagemaker update-cluster \
  --cluster-name {{cluster-name}} \
  --instance-groups '[ \
        { \
            "InstanceCount": {{1}},\
            "InstanceGroupName": "{{controller-nodes}}",\
            "InstanceType": "{{ml.t3.xlarge}}",\
            "LifeCycleConfig": {"SourceS3Uri": {{source_s3_uri}}, "OnCreate": "on_create.sh"},\
            "ExecutionRole": "arn:aws:iam::{{customer_account_id}}:role/{{execution_role}}",\
            "ThreadsPerCore": {{1}},\
        },\
        { \
            "InstanceCount": {{2}}, \
            "InstanceGroupName": "{{worker-nodes}}",\
            "InstanceType": "{{p4d.24xlarge}}",\
            "LifeCycleConfig": {"SourceS3Uri": {{source_s3_uri}}, "OnCreate": "on_create.sh"},\
            "ExecutionRole": "arn:aws:iam::{{customer_account_id}}}:role/{{execution_role}}}",\
            "ThreadsPerCore": {{1}},\
            "TrainingPlanArn": {{training_plan_arn}},\
        },\
        {\
            "InstanceCount": {{1}},\
            "InstanceGroupName": "{{worker-nodes-2}}",\
            "InstanceType": "{{p4d.24xlarge}}",\
            "LifeCycleConfig": {"SourceS3Uri": {{source_s3_uri}}, "OnCreate": "on_create.sh"},\
            "ExecutionRole": "arn:aws:iam::{{customer_account_id}}:role/{{execution_role}}",\
            "ThreadsPerCore": {{1}},\
            "TrainingPlanArn": {{training_plan_arn}},\
        }\
    ]'
