編譯模型 (AWS Command Line Interface)
本節說明如何使用 AWS Command Line Interface () 管理機器學習模型的 Amazon SageMaker Neo 編譯任CLI務。您可以建立、描述、停止和列出編譯任務。
建立編譯任務
透過此CreateCompilationJobAPI作業,您可以指定資料輸入格式、用於存放模型的 S3 儲存貯體、要寫入編譯模型的 S3 儲存貯體,以及目標硬體裝置或平台。
下表演示瞭如何CreateCompilationJob
API根據您的目標是設備還是平台進行配置。
- Device Example
-
{
"CompilationJobName": "neo-compilation-job-demo
",
"RoleArn": "arn:aws:iam::<your-account>
:role/service-role/AmazonSageMaker-ExecutionRole-yyyymmddThhmmss
",
"InputConfig": {
"S3Uri": "s3://<your-bucket>
/sagemaker/neo-compilation-job-demo-data/train
",
"DataInputConfig": "{'data': [1,3,1024,1024]}
",
"Framework": "MXNET
"
},
"OutputConfig": {
"S3OutputLocation": "s3://<your-bucket>
/sagemaker/neo-compilation-job-demo-data/compile
",
# A target device specification example for a ml_c5 instance family
"TargetDevice": "ml_c5
"
},
"StoppingCondition": {
"MaxRuntimeInSeconds": 300
}
}
如果您使用框架來訓練模型,並且目標設備是目標,則可以選擇性地指定用於該FrameworkVersion
字段的 PyTorch 框架版本。ml_*
{
"CompilationJobName": "neo-compilation-job-demo",
"RoleArn": "arn:aws:iam::<your-account>
:role/service-role/AmazonSageMaker-ExecutionRole-yyyymmddThhmmss",
"InputConfig": {
"S3Uri": "s3://<your-bucket>
/sagemaker/neo-compilation-job-demo-data/train",
"DataInputConfig": "{'data': [1,3,1024,1024]}",
"Framework": "PYTORCH",
"FrameworkVersion": "1.6"
},
"OutputConfig": {
"S3OutputLocation": "s3://<your-bucket>
/sagemaker/neo-compilation-job-demo-data/compile",
# A target device specification example for a ml_c5 instance family
"TargetDevice": "ml_c5",
# When compiling for ml_* instances using PyTorch framework, use the "CompilerOptions" field in
# OutputConfig to provide the correct data type ("dtype") of the model’s input. Default assumed is "float32"
"CompilerOptions": "{'dtype': 'long'}"
},
"StoppingCondition": {
"MaxRuntimeInSeconds": 300
}
}
- Platform Example
-
{
"CompilationJobName": "neo-test-compilation-job
",
"RoleArn": "arn:aws:iam::<your-account>:
role/service-role/AmazonSageMaker-ExecutionRole-yyyymmddThhmmss
",
"InputConfig": {
"S3Uri": "s3://<your-bucket>
/sagemaker/neo-compilation-job-demo-data/train
",
"DataInputConfig": "{'data': [1,3,1024,1024]}
",
"Framework": "MXNET
"
},
"OutputConfig": {
"S3OutputLocation": "s3://<your-bucket>
/sagemaker/neo-compilation-job-demo-data/compile
",
# A target platform configuration example for a p3.2xlarge instance
"TargetPlatform": {
"Os": "LINUX
",
"Arch": "X86_64
",
"Accelerator": "NVIDIA
"
},
"CompilerOptions": "{'cuda-ver': '10.0', 'trt-ver': '6.0.1', 'gpu-code': 'sm_70'
}"
},
"StoppingCondition": {
"MaxRuntimeInSeconds": 300
}
}
對於OutputConfig
API作業而言,TargetDevice
和TargetPlatform
API運算是互斥的。您必須選擇兩個選項之一。
要查找取DataInputConfig
決於框架的JSON字符串示例,請參閱 Neo 期望的輸入數據形狀。
如需有關設定模型組態的詳細資訊 InputConfigOutputConfig,請參閱 SageMaker API參照中的、和TargetPlatformAPI操作。
設定JSON檔案後,請執行下列命令以建立編譯工作:
aws sagemaker create-compilation-job \
--cli-input-json file://job.json \
--region us-west-2
# You should get CompilationJobArn
執行下列命令,描述編譯任務:
aws sagemaker describe-compilation-job \
--compilation-job-name $JOB_NM \
--region us-west-2
執行下列命令,停止編譯任務:
aws sagemaker stop-compilation-job \
--compilation-job-name $JOB_NM \
--region us-west-2
# There is no output for compilation-job operation
執行下列命令,列出編譯任務:
aws sagemaker list-compilation-jobs \
--region us-west-2
