https://your-neptune-endpoint:port \ --id "(a unique model-training job ID)" \ --data-processing-job-id "(the data-processing job-id of a completed job)" \ --train-model-s3-location "s3://(your S3 bucket)/neptune-model-graph-autotrainer" ``` 如需詳細資訊，請參閱《 AWS CLI 命令參考》中的 [start-ml-model-training-job](https://docs.aws.amazon.com/cli/latest/reference/neptunedata/start-ml-model-training-job.html)。 ------ #### [ SDK ] ``` 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_training_job( id='(a unique model-training job ID)', dataProcessingJobId='(the data-processing job-id of a completed job)', trainModelS3Location='s3://(your S3 bucket)/neptune-model-graph-autotrainer' ) print(response) ``` ------ #### [ awscurl ] ``` awscurl https://your-neptune-endpoint:port/ml/modeltraining \ --region us-east-1 \ --service neptune-db \ -X POST \ -H 'Content-Type: application/json' \ -d '{ "id" : "(a unique model-training job ID)", "dataProcessingJobId" : "(the data-processing job-id of a completed job)", "trainModelS3Location" : "s3://(your S3 bucket)/neptune-model-graph-autotrainer" }' ``` **注意** 此範例假設您的 AWS 登入資料已在您的環境中設定。將 *us-east-1* 取代為 Neptune 叢集的區域。 ------ #### [ curl ] ``` curl \ -X POST https://your-neptune-endpoint:port/ml/modeltraining \ -H 'Content-Type: application/json' \ -d '{ "id" : "(a unique model-training job ID)", "dataProcessingJobId" : "(the data-processing job-id of a completed job)", "trainModelS3Location" : "s3://(your S3 bucket)/neptune-model-graph-autotrainer" }' ``` ------ 如何使用此命令的詳細資訊會在 [modeltraining 指令](machine-learning-api-modeltraining.md) 中加以說明，伴隨如何取得執行中工作狀態、如何停止執行中工作，以及如何列出所有執行中工作的相關資訊。 您也可以提供一個 `previousModelTrainingJobId`，使用來自已完成 Neptune ML 模型訓練工作的資訊，以在新的訓練工作中加速超參數搜尋。在[對新圖形資料進行模型重新訓練](machine-learning-overview-evolving-data-incremental.md#machine-learning-overview-model-retraining)期間，以及在[對相同圖形資料進行增量訓練](machine-learning-overview-evolving-data-incremental.md#machine-learning-overview-incremental)期間，這樣做很有用。使用像這樣的命令： ------ #### [ AWS CLI ] ``` aws neptunedata start-ml-model-training-job \ --endpoint-url https://your-neptune-endpoint:port \ --id "(a unique model-training job ID)" \ --data-processing-job-id "(the data-processing job-id of a completed job)" \ --train-model-s3-location "s3://(your S3 bucket)/neptune-model-graph-autotrainer" \ --previous-model-training-job-id "(the model-training job-id of a completed job)" ``` 如需詳細資訊，請參閱《 AWS CLI 命令參考》中的 [start-ml-model-training-job](https://docs.aws.amazon.com/cli/latest/reference/neptunedata/start-ml-model-training-job.html)。 ------ #### [ SDK ] ``` 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_training_job( id='(a unique model-training job ID)', dataProcessingJobId='(the data-processing job-id of a completed job)', trainModelS3Location='s3://(your S3 bucket)/neptune-model-graph-autotrainer', previousModelTrainingJobId='(the model-training job-id of a completed job)' ) print(response) ``` ------ #### [ awscurl ] ``` awscurl https://your-neptune-endpoint:port/ml/modeltraining \ --region us-east-1 \ --service neptune-db \ -X POST \ -H 'Content-Type: application/json' \ -d '{ "id" : "(a unique model-training job ID)", "dataProcessingJobId" : "(the data-processing job-id of a completed job)", "trainModelS3Location" : "s3://(your S3 bucket)/neptune-model-graph-autotrainer", "previousModelTrainingJobId" : "(the model-training job-id of a completed job)" }' ``` **注意** 此範例假設您的 AWS 登入資料已在您的環境中設定。將 *us-east-1* 取代為 Neptune 叢集的區域。 ------ #### [ curl ] ``` curl \ -X POST

completed job)", "trainModelS3Location" : "s3://(your S3 bucket)/neptune-model-graph-autotrainer", "previousModelTrainingJobId" : "(the model-training job-id of a completed job)" }' ``` ------ 您可以提供 `customModelTrainingParameters` 物件，在 Neptune ML 訓練基礎結構上訓練自己的模型實作，如下所示： ------ #### [ AWS CLI ] ``` aws neptunedata start-ml-model-training-job \ --endpoint-url https://your-neptune-endpoint:port \ --id "(a unique model-training job ID)" \ --data-processing-job-id "(the data-processing job-id of a completed job)" \ --train-model-s3-location "s3://(your Amazon S3 bucket)/neptune-model-graph-autotrainer" \ --model-name "custom" \ --custom-model-training-parameters '{ "sourceS3DirectoryPath": "s3://(your Amazon S3 bucket)/(path to your Python module)", "trainingEntryPointScript": "(your training script entry-point name in the Python module)", "transformEntryPointScript": "(your transform script entry-point name in the Python module)" }' ``` 如需詳細資訊，請參閱《 AWS CLI 命令參考》中的 [start-ml-model-training-job](https://docs.aws.amazon.com/cli/latest/reference/neptunedata/start-ml-model-training-job.html)。 ------ #### [ SDK ] ```
