MLInstances端点

MLInstance是现有引擎包含一组适当的配置，可定义任何训练参数、评分参数或硬件资源配置。

创建MLInstance

您可以创建MLInstance，方法是在提供包含有效引擎ID的请求有效负载时执行POST请求({ENGINE_ID})和一组适当的默认配置。

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，则可以选择使用CPU或GPU进行训练和评分。请参阅附录中关于 PySpark和Spark资源配置和 Python CPU和GPU配置了解更多信息。

更新MLInstance

您可以更新现有MLInstance，方法是通过PUT请求（请求路径中包含Target MLInstance的ID）覆盖其属性，并提供包含已更新属性的JSON有效负载。

小贴士

为了确保此PUT请求成功，建议您首先执行GET请求按ID检索MLInstance. 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调用最初具有这些属性时，将更新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",

    },
    "tasks": [
        {
            "name": "train",
            "parameters": [
                {
                    "key": "learning_rate",
                    "value": "0.3"
                }
            ]
        },
        {
            "name": "score",
            "parameters": [
                {
                    "key": "output_dataset_id",
