查看数据偏差偏移报告

如果您无法在 SageMaker Studio 中查看生成的报告中的监控结果，则可以按如下方式将其打印出来：

schedule_desc = model_bias_monitor.describe_schedule()
execution_summary = schedule_desc.get("LastMonitoringExecutionSummary")
if execution_summary and execution_summary["MonitoringExecutionStatus"] in ["Completed", "CompletedWithViolations"]:
    last_model_bias_monitor_execution = model_bias_monitor.list_executions()[-1]
    last_model_bias_monitor_execution_report_uri = last_model_bias_monitor_execution.output.destination
    print(f'Report URI: {last_model_bias_monitor_execution_report_uri}')
    last_model_bias_monitor_execution_report_files = sorted(S3Downloader.list(last_model_bias_monitor_execution_report_uri))
    print("Found Report Files:")
    print("\n ".join(last_model_bias_monitor_execution_report_files))
else:
    last_model_bias_monitor_execution = None
    print("====STOP==== \n No completed executions to inspect further. Please wait till an execution completes or investigate previously reported failures.")

如果与基准相比存在违规情况，则在此列出：

if last_model_bias_monitor_execution:
    model_bias_violations = last_model_bias_monitor_execution.constraint_violations()
    if model_bias_violations:
        print(model_bias_violations.body_dict)

如果您的模型部署到实时端点，则可以在 SageMaker Studio 中查看分析结果和 CloudWatch 指标的可视化效果，方法是选择 Endpoints 选项卡，然后双击该端点。
