MLInstances終結點

MLInstance是現有 引擎 使用一組適當的配置,這些配置定義任何培訓參數、評分參數或硬體資源配置。

建立MLInstance

您可以通過在提供由有效引擎ID({ENGINE_ID})和一組適當的預設配置。

如果引擎ID引用PySpark或Spark引擎,則您可以配置計算資源量,如內核數或記憶體量。 如果引用了Python引擎,則可以選擇使用CPU或GPU進行培訓和評分。 請參閱附錄部分。 PySpark和Spark資源配置Python CPU和GPU配置 的子菜單。

更新MLInstance

您可以通過PUT請求覆蓋現有MLInstance的屬性,該請求將目標MLInstance的ID包括在請求路徑中,並提供包含已更新屬性的JSON負載,來更新現有MLInstance。

秘訣

為確保此PUT請求成功,建議您首先執行GET請求, 按ID檢索MLInstance。 然後,修改和更新返回的JSON對象,並應用已修改的JSON對象的整個作為PUT請求的負載。

以下示例API調用將更新MLInstance的訓練和計分參數,同時初始具有這些屬性:

{
    "name": "A name for this MLInstance",
    "description": "A description for this MLInstance",
    "engineId": "00000000-0000-0000-0000-000000000000",
