Creating a solution version

After you have completed Creating and configuring a solution, you are ready to create a solution version. A solution version refers to a trained machine learning model. A solution version is a custom resource. You can deploy a solution version with an Amazon Personalize campaign. You use the campaign to get recommendations for users. And you can use a solution version to get batch recommendations.

You can create a solution version using the console, AWS Command Line Interface (AWS CLI), or AWS SDKs. If your solution version has a status of CREATE_PENDING or CREATE_IN_PROGRESS, you can use the StopSolutionVersionCreation operation to stop the solution version creation process. See Stopping the creation of a solution version.

Creating a solution version (console)

When you initially create your solution with the Amazon Personalize console, you also create a solution version. On the solution details page, you can track training progress in the Solution versions section. When training is complete, the status is Active and you are ready to deploy a campaign and get recommendations. See Creating a campaign.

If you want to create an additional solution version for an existing solution, create a new solution version from the solution overview page as follows.

To create a new solution version

Open the Amazon Personalize console at https://console.aws.amazon.com/personalize/home and sign into your account.
Navigate to the dataset groups page and choose the dataset group with your new solution.
In the navigation pane, choose Solutions and recipes.
On the Solution and recipes page, choose the solution you want to create a solution version for.
On the solution overview page, choose Create solution version to start training a new model.

On the solution details page, you can track training progress in the Solution versions section. When training is complete, the status is Active you can evaluate it using metrics supplied by Amazon Personalize. For more information, see Evaluating a solution version with metrics.

If training does not complete because of an error, you are not charged for the training. If your solution version has a status of CREATE_PENDING or CREATE_IN_PROGRESS, you can stop the solution version creation process. To stop solution version creation, navigate to the solution version details page and choose Stop. See Stopping the creation of a solution version.

Creating a solution version (AWS CLI)

When your solution is ACTIVE, train the model by running the following command. Replace solution arn with the solution Amazon Resource Name (ARN) from Creating and configuring a solution.


aws personalize create-solution-version \
  --solution-arn solution arn

The solution version ARN is displayed, for example:


{
  "solutionVersionArn": "arn:aws:personalize:us-west-2:acct-id:solution/SolutionName/<version-id>"
}

Check the training status of the solution version by using the describe-solution-version command. Provide the solution version ARN that was returned in the previous step. For more information about the API, see DescribeSolutionVersion.


aws personalize describe-solution-version \
  --solution-version-arn solution version arn

The properties of the solution version and the training status are displayed. Initially, the status shows as CREATE PENDING, for example:


{
  "solutionVersion": {
      "solutionVersionArn": "arn:aws:personalize:us-west-2:acct-id:solution/solutionName/<version-id>",
      ...,
      "status": "CREATE PENDING"
  }
}

Training is complete when the status is ACTIVE and you can evaluate it using metrics supplied by Amazon Personalize. For more information, see Evaluating a solution version with metrics. If training does not complete because of an error, you are not charged for the training.

If your solution version has a status of CREATE_PENDING or CREATE_IN_PROGRESS, you can use the StopSolutionVersionCreation operation to stop the solution version creation process. See Stopping the creation of a solution version.

Creating a solution version (AWS SDKs)

When your solution is ACTIVE, use the following code to create a solution version. Specify the Amazon Resource Name (ARN) from Creating and configuring a solution. Use the DescribeSolutionVersion operation to retrieve the solution version's status.

SDK for Python (Boto3)


import boto3

personalize = boto3.client('personalize')
# Store the solution ARN
solution_arn = 'solution arn'
        
# Use the solution ARN to get the solution status.
solution_description = personalize.describe_solution(solutionArn = 'solution_arn')['solution']
print('Solution status: ' + solution_description['status'])

# Use the solution ARN to create a solution version.
print ('Creating solution version')
response = personalize.create_solution_version(solutionArn = solution_arn)
solution_version_arn = response['solutionVersionArn']
print('Solution version ARN: ' + solution_version_arn)

# Use the solution version ARN to get the solution version status.
solution_version_description = personalize.describe_solution_version(
    solutionVersionArn = solution_version_arn)['solutionVersion']
print('Solution version status: ' + solution_version_description['status'])

SDK for Java 2.x

                    solutionVersionStatus = personalizeClient.describeSolutionVersion(describeSolutionVersionRequest).solutionVersion().status();
                    System.out.println("Solution version status: " + solutionVersionStatus);

SDK for JavaScript v3


// Get service clients module and commands using ES6 syntax.
import { CreateSolutionVersionCommand } from
  "@aws-sdk/client-personalize";
import { personalizeClient } from "./libs/personalizeClients.js";
// Or, create the client here.
// const personalizeClient = new PersonalizeClient({ region: "REGION"});

// Set the solution version parameters.
export const solutionVersionParam = {
  solutionArn: 'SOLUTION_ARN' /* required */
}

export const run = async () => {
  try {
    const response = await personalizeClient.send(new CreateSolutionVersionCommand(solutionVersionParam));
    console.log("Success", response);
    return response; // For unit tests.
  } catch (err) {
    console.log("Error", err);
  }
};
run();

To check the current solution version status, call the DescribeSolutionVersion operation and pass the ARN of the solution version returned from the CreateSolutionVersion operation. Training is complete when the status is ACTIVE and you can evaluate it using metrics supplied by Amazon Personalize. For more information, see Evaluating a solution version with metrics. If training does not complete because of an error, you are not charged for the training.
