c# - VideoDetector.start 抛出异常“初始化失败，数据文件夹无效”

Question

VideoDetector 在调用Detector.start()方法时抛出以下异常。

初始化失败，数据文件夹无效

我的 classifierPath 设置正确为C:\Program Files\Affectiva\AffdexSDK\data

我错过了什么吗？

代码：

private static string classifierPath = @"C:\Program Files\Affectiva\AffdexSDK\data";
VideoDetector detector = new VideoDetector();
detector.setClassifierPath(classifierPath);
var processor = new AffectivaProcessor(ref AffectivaResult, ref stopProcessing, detectExpressions, detectEmotions, detectEmojis, detectAppearance);

detectorHandler = new AffectivaDetectorHandler(processor);
detector.setFaceListener(processor);
detector.setImageListener(processor);
detector.setProcessStatusListener(processor);

detector.setDetectAllExpressions(detectExpressions);
detector.setDetectAllEmotions(detectEmotions);
detector.setDetectAllEmojis(detectEmojis);
detector.setDetectAllAppearances(detectAppearance);

detector.start();
detector.process(videoFilePath);
detectorHandler.WaitTillProcessing();
detector.stop();
