LearningModelSessionOptions 类

定义

命名空间:

Windows.AI.MachineLearning

介绍在创建 LearningModelSession 对象期间使用的推理选项。

public ref class LearningModelSessionOptions sealed

/// [Windows.Foundation.Metadata.Activatable(131072, "Windows.AI.MachineLearning.MachineLearningContract")]
/// [Windows.Foundation.Metadata.ContractVersion(Windows.AI.MachineLearning.MachineLearningContract, 131072)]
/// [Windows.Foundation.Metadata.MarshalingBehavior(Windows.Foundation.Metadata.MarshalingType.Agile)]
/// [Windows.Foundation.Metadata.Threading(Windows.Foundation.Metadata.ThreadingModel.Both)]
class LearningModelSessionOptions final

[Windows.Foundation.Metadata.Activatable(131072, "Windows.AI.MachineLearning.MachineLearningContract")]
[Windows.Foundation.Metadata.ContractVersion(typeof(Windows.AI.MachineLearning.MachineLearningContract), 131072)]
[Windows.Foundation.Metadata.MarshalingBehavior(Windows.Foundation.Metadata.MarshalingType.Agile)]
[Windows.Foundation.Metadata.Threading(Windows.Foundation.Metadata.ThreadingModel.Both)]
public sealed class LearningModelSessionOptions

function LearningModelSessionOptions()

Windows 要求

设备系列	Windows 10, version 1903 (在 10.0.18362.0 中引入)
API contract	Windows.AI.MachineLearning.MachineLearningContract (在 v2.0 中引入)

示例

以下示例创建 LearningModelSessionOptions 对象，以便在会话创建期间使用。

private LearningModelSessionOptions CreateSessionOptions()
{
    var options = new LearningModelSessionOptions();

    // Disable constant batch size optimizations
    options.BatchSizeOverride = 0;

    return options;
}

注解

LearningModelSessionOptions 对象可用于配置 LearningModelSession 构造。
