将Mediapipe人脸跟踪示例修改为鞋子检测时，ValidateRequiredSidePackets失败错误

Question

我已按照these 的说明获取资产和.aar文件以进行鞋子检测，然后将它们作为发光的here进行了导入。

• object_detection_3d_sneakers.tflite
• objectdetection3d.binarypb
• ssdlite_object_detection_labelmap.txt 放入资产文件夹并 和
• mp_object_detection_3d.aar

进入资产文件夹

• mp_object_detection_3d.aar

进入 libs 文件夹。

我在人脸检测中使用了最相似的示例项目，并如上所述交换了各自的文件。

构建成功，但是在android设备上运行它后出现错误：
