MLInstance是现有引擎与定义任何培训参数、评分参数或硬件资源配置的适当配置集的配对。

创建MLInstance create-an-mlinstance

通过在提供包含有效引擎ID ({ENGINE_ID})和一组适当的默认配置的请求负载时执行POST请求，可以创建MLInstance。

如果引擎ID引用PySpark或Spark引擎，则您能够配置计算资源的数量，例如核心数量或内存量。 如果引用了Python引擎，则可以在使用CPU或GPU之间进行选择，以进行培训和评分。 请参阅附录中有关PySpark和Spark资源配置以及Python CPU和GPU配置的部分以了解更多信息。

更新MLInstance

您可以更新现有MLInstance，方法是通过PUT请求覆盖其属性，该请求在请求路径中包含目标MLInstance的ID，并提供包含更新属性的JSON负载。

TIP
为了确保此PUT请求成功，建议您首先执行按ID检索MLInstance的GET请求。 然后，修改并更新返回的JSON对象，并将修改后的JSON对象的整个内容应用为PUT请求的有效负载。

以下示例API调用将在最初具有这些属性时更新MLInstance的训练和评分参数：

{
    "name": "A name for this MLInstance",
    "description": "A description for this MLInstance",
    "engineId": "00000000-0000-0000-0000-000000000000",
    "created": "2019-01-01T00:00:00.000Z",
    "createdBy": {
        "displayName": "Jane Doe",
        "userId": "Jane_Doe@AdobeID"
    },
    "tasks": [
        {
            "name": "train",
            "parameters": [
                {
                    "key": "learning_rate",
                    "value": "0.3"
                }
            ]
        },
        {
            "name": "score",
            "parameters": [
                {
