MediaPipe 如何使用BoxTracking aar？

Question

刚接触MediaPipe，对图、节点、子图等概念不熟悉

在构建 BoxTracking 的 aar 文件后，由于一些未知的输入和输出参数需要，无法在基于 Android Studio gradle 的项目中运行它型号

比较HandTracking graph BoxTracking graph using the visualizer tool and with a working project of HandTracking 将 aar 文件添加为 lib，我添加了新的必需输入流和侧数据包，如图所示。

结果总是有些错误，主要是输入有问题，或者直接使用BoxTracking是子图。如何知道运行需要哪个输入以及输入的数据类型？

默认构建中未包含输入和输出所需的数据类型，必须修改构建配置以包含 box_tracker.proto 及其依赖项。
