Inhalt der JSON-Datei als Python-Wörterverzeichnis laden

Im vorliegenden Beispiel sind in der Datei sagemaker_native_multiclass_breast-cancer_all_monitors_sub_configuration.json die Konfigurationsdaten für ein Vorhersagemodell der Krebsart definiert.

Führen Sie den folgenden Befehl aus, um die Datei in Python zu laden:

configuration_file_path = 'sagemaker_native_multiclass_breast-cancer_all_monitors_sub_configuration.json'

  with open(configuration_file_path, 'r') as fp:
subscription_configuration = json.load(fp)

Die Datei enthält ähnliche Konfigurationsdaten wie das folgende Beispiel. Im Notebook finden Sie ein vollständiges Beispiel für den Inhalt der Konfiguration.

Aus Konfigurationsdatei importieren

Führen Sie nun den Aufruf aus, um die Assetbereitstellung für das Beispielvorhersagemodell für Brustkrebs hinzuzufügen und zu konfigurieren.

subscription = client.data_mart.subscriptions.import_configuration(binding_uid=binding_uid, configuration_data=subscription_configuration)

Der Parameter binding_uid ist optional, wenn nur eine einzige Engine für maschinelles Lernen gebunden wird.

In Konfigurationsdatei exportieren

Die Konfigurationsdatei kann auch im JSON-Format exportiert werden:

exported_configuration = client.data_mart.subscriptions.export_configuration(binding_uid=binding_uid, subscription_uid=subscription.uid)

Ergebnisse

Das Asset Deployment ist erstellt und kann für Modellevaluierungen verwendet werden.
