更新 Amazon Personalize 指标归因
更新指标归因时，您可以添加和移除指标以及修改其输出配置。您可以使用 Amazon Personalize 控制台、Amazon Command Line Interface 或 Amazon SDK 更新指标归因。
更新指标归因（控制台）
要使用 Amazon Personalize 控制台更新指标归因，您可以在指标归因页面上进行更改。
更新指标归因 (Amazon CLI)
创建指标归因后，您可以使用 Amazon Command Line Interface (Amazon CLI) 添加和移除指标以及修改其输出配置。以下代码显示了如何使用 update-metric-attribution 命令删除指标：
aws personalize update-metric-attribution \
--metric-attribution-arn metric attribution arn \
--remove-metrics metricName1 metricName2
以下代码显示了如何添加其他指标和指定新的输出配置：
aws personalize update-metric-attribution \
--metric-attribution-arn metric attribution arn \
--metrics-output-config "{\"roleArn\": \"new role ARN\", \"s3DataDestination\":{\"kmsKeyArn\":\"kms key ARN\",\"path\":\"s3://amzn-s3-demo-bucket2/new-folder-name/\"}}" \
--add-metrics "[{
\"eventType\": \"event type\",
\"expression\": \"SUM(DatasetType.COLUMN_NAME)\",
\"metricName\": \"metric name\"
}]"
如果成功，则 Amazon Personalize 会返回您更新的指标归因的 ARN。要获得所有参数的完整列表，请参阅 UpdateMetricAttribution。
更新指标归因 (Amazon SDK)
创建指标归因后，您可以添加或移除指标以及修改其输出配置。以下代码显示了如何从指标归因中移除指标。
- SDK for Python (Boto3)
-
import boto3
personalize = boto3.client('personalize')

response = personalize.update_metric_attribution(
metricAttributionArn = "metric attribution ARN",
removeMetrics = metricsToRemove
)
- SDK for Java 2.x
-
public static void removeMetrics(PersonalizeClient client,
String metricAttributionArn,

UpdateMetricAttributionRequest request = UpdateMetricAttributionRequest.builder()
.metricAttributionArn(metricAttributionArn)
.removeMetrics(metricsToRemove)
.build();
UpdateMetricAttributionResponse response = client.updateMetricAttribution(request);
System.out.println(response);
} catch (PersonalizeException e) {
System.out.println(e.awsErrorDetails().errorMessage());
}
}
