You use the Neptune ML `modeltransform` command to create a model transform job, check its status, stop it, or list all active model-transform jobs.

## Creating a model-transform job using the Neptune ML `modeltransform` command
<a name="machine-learning-api-modeltransform-create-job"></a>

A Neptune ML `modeltransform` command for creating an incremental transform job, without model retraining, looks like this:

------
#### [ 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 job-id of a completed data-processing job)" \
  --ml-model-training-job-id "(the job-id of a completed model-training job)" \
  --model-transform-output-s3-location "s3://(your S3 bucket)/neptune-model-transform"
```

+ **`mlModelTrainingJobId`**   –   The job Id of a completed model-training job.

  *Type*: string.

  *Note*: You must include either both `dataProcessingJobId` and `mlModelTrainingJobId`, or `trainingJobName`.
+ **`trainingJobName`**   –   The name of a completed SageMaker AI training job.

  *Type*: string. *Note*: This must be listed in your DB cluster parameter group or an error will occur.
+ **`neptuneIamRoleArn`**   –   (*Optional*) The ARN of an IAM role that provides Neptune access to SageMaker AI and Amazon S3 resources.

  *Type*: string. *Note*: This must be listed in your DB cluster parameter group or an error will occur.
+ **`customModelTransformParameters `**   –   (*Optional*) Configuration information for a model transform using a custom model. The `customModelTransformParameters` object contains the following fields, which must have values compatible with the saved model parameters from the training job:
  + **`sourceS3DirectoryPath`**   –   (*Required*) The path to the Amazon S3 location where the Python module implementing your model is located. This must point to a valid existing Amazon S3 location that contains, at a minimum, a training script, a transform script, and a `model-hpo-configuration.json` file.
  + **`transformEntryPointScript`**   –   (*Optional*) The name of the entry point in your module of a script that should be run after the best model from the hyperparameter search has been identified, to compute the model artifacts necessary for model deployment. It should be able to run with no command-line arguments.

    *Default*: `transform.py`.

  *Type*: integer. *Default*: `0`.

  *Note*: If not specified or 0, Neptune ML selects a disk volume size based on the recommendation generated in the data processing step. See [Selecting an instance for model training and model transform](machine-learning-on-graphs-instance-selection.md#machine-learning-on-graphs-training-transform-instance-size).
+ **`subnets`**   –   (*Optional*) The IDs of the subnets in the Neptune VPC.

  *Type*: string. *Default*: *none*.
+ **`enableInterContainerTrafficEncryption`**   –   (*Optional*) Enable or disable inter-container traffic encryption in training or hyper-parameter tuning jobs.

  *Type*: boolean. *Default*: *True*.
**Note**  
The `enableInterContainerTrafficEncryption` parameter is only available in [engine release 1.2.0.2.R3](engine-releases-1.2.0.2.R3.md).
+ **`s3OutputEncryptionKMSKey`**   –   (*Optional*) The AWS Key Management Service (AWS KMS) key that SageMaker AI uses to encrypt the output of the processing job.
