API contract	Windows.AI.MachineLearning.MachineLearningContract (introduced in v2.0)

Examples

The following example creates a LearningModelSessionOptions object for use during session creation.

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

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

    return options;
}

Remarks

The LearningModelSessionOptions object can be used to configure LearningModelSession construction.
