Diese Legacy-Version von AutoML Vision wurde verworfen und ist nach dem 31. März 2024 nicht mehr in Google Cloud verfügbar. Die gesamte Funktionalität von AutoML Vision und neue Features sind auf der Vertex AI-Plattform verfügbar. Informationen zum Migrieren Ihrer Ressourcen finden Sie unter Zu Vertex AI migrieren.
