建立對象：

Developer

MLInstance是現有引擎搭配適當的設定集，以定義任何訓練引數、評分引數或硬體資源設定。

建立MLInstance create-an-mlinstance

您可以在提供包含有效引擎ID的要求裝載時，透過執行POST要求來建立MLInstance ({ENGINE_ID})和一組適當的預設設定。

如果「引擎ID」參照PySpark或Spark引擎，則您可以設定計算資源的數量，例如核心數量或記憶體數量。如果參考了Python引擎，您可以選擇使用CPU或GPU進行訓練和評分。請參閱附錄中有關 PySpark和Spark資源設定和 Python CPU和GPU設定以取得詳細資訊。

更新MLInstance

您可以透過PUT要求（要求路徑中包含Target MLInstance的ID）覆寫其屬性，並提供包含已更新屬性的JSON裝載，以更新現有的MLInstance。

TIP

為確保此PUT請求成功，建議您先執行GET請求，並依ID擷取MLInstance. 然後，修改和更新傳回的JSON物件，並套用整個修改的JSON物件作為PUT請求的裝載。

下列範例API呼叫最初具有這些屬性時，將會更新MLInstance的訓練和評分引數：
