使用 Neptune ML 模型转换命令,您可以使用预训练的模型参数计算模型构件,例如已处理的图形数据上的节点嵌入。
在增量模型推理工作流程中,处理完从 Neptune 导出的更新图形数据后,可以使用如下命令启动模型转换作业:
- AWS CLI
-
aws neptunedata start-ml-model-transform-job \
--endpoint-url https://your-neptune-endpoint:port \
--id "(a unique model-transform job ID)" \
--data-processing-job-id "(the data-processing job-id of a completed job)" \
--ml-model-training-job-id "(the ML model training job-id)" \
--model-transform-output-s3-location "s3://(your S3 bucket)/neptune-model-transform/"
有关更多信息,请参阅《 AWS CLI 命令参考》中的 start-ml-model-transform-job。

import boto3
from botocore.config import Config
client = boto3.client(
'neptunedata',
endpoint_url='https://your-neptune-endpoint:port',
config=Config(read_timeout=None, retries={'total_max_attempts': 1})
)
response = client.start_ml_model_transform_job(
id='(a unique model-transform job ID)',
dataProcessingJobId='(the data-processing job-id of a completed job)',
mlModelTrainingJobId='(the ML model training job-id)',
modelTransformOutputS3Location='s3://(your S3 bucket)/neptune-model-transform/'
)
print(response)
- awscurl
-
awscurl https://your-neptune-endpoint:port/ml/modeltransform \
--region us-east-1 \
--service neptune-db \
-X POST \
-H 'Content-Type: application/json' \
-d '{
"id" : "(a unique model-transform job ID)",
"dataProcessingJobId" : "(the data-processing job-id of a completed job)",
"mlModelTrainingJobId": "(the ML model training job-id)",
"modelTransformOutputS3Location" : "s3://(your S3 bucket)/neptune-model-transform/"
}'
此示例假设您的 AWS 证书是在您的环境中配置的。us-east-1替换为 Neptune 集群的区域。

curl \
-X POST https://your-neptune-endpoint:port/ml/modeltransform \
-H 'Content-Type: application/json' \
-d '{
"id" : "(a unique model-transform job ID)",
"dataProcessingJobId" : "(the data-processing job-id of a completed job)",
"mlModelTrainingJobId": "(the ML model training job-id)",
"modelTransformOutputS3Location" : "s3://(your S3 bucket)/neptune-model-transform/"
}'
然后,您可以将此任务的 ID 传递给 create-endpoints API 调用,以创建新的端点,或者使用此任务生成的新模型构件更新现有端点。这允许新的或更新的端点为更新后的图形数据提供模型预测。
您还可以提供一个trainingJobName参数来为在 Neptune ML 模型训练期间启动的任何 SageMaker AI 训练作业生成模型工件。由于 Neptune ML 模型训练作业可能会启动许多 SageMaker AI 训练作业,因此您可以灵活地基于任何 SageMaker AI 训练作业创建推理端点。
例如:
- AWS CLI
-
aws neptunedata start-ml-model-transform-job \
--endpoint-url https://your-neptune-endpoint:port \
--id "(a unique model-transform job ID)" \
--training-job-name "(name of a completed SageMaker training job)" \
--model-transform-output-s3-location "s3://(your S3 bucket)/neptune-model-transform/"

如果原始训练任务是针对用户提供的自定义模型,则在调用模型转换时必须包含一个 customModelTransformParameters 对象。有关如何实现和使用自定义模型的信息,请参阅Neptune ML 中的自定义模型。
该modeltransform命令始终在最适合该训练的 SageMaker AI 训练作业上运行模型变换。
