MLInstances端點

MLInstance是現有引擎與定義任何訓練參數、計分參數或硬體資源配置的一組適當配置的配對。

建立MLInstance

您可以在提供由有效引擎ID({ENGINE_ID})和一組適當的預設組態組成的請求裝載時，執行POST請求，以建立MLInstance。

如果引擎ID參照PySpark或Spark引擎，則您可以設定計算資源量，例如內核數或記憶體量。 如果參考了Python引擎，則您可以選擇使用CPU或GPU進行訓練和計分。 如需詳細資訊，請參閱PySpark和Spark資源組態和Python CPU和GPU組態的附錄部分。

更新MLInstance

您可以透過PUT請求覆寫現有MLInstance的屬性，該請求在請求路徑中包含目標MLInstance的ID，並提供包含更新屬性的JSON裝載，借此更新現有MLInstance。

秘訣

為確保此PUT請求成功，建議您首先執行GET請求，以按ID🔗檢索MLInstance。 然後，修改並更新傳回的JSON物件，並套用已修改的JSON物件作為PUT要求的裝載。

下列範例API呼叫會在初步擁有這些屬性的同時，更新MLInstance的訓練和計分參數：
