android - Mediapipe 跟踪 AAR 构建失败：按架构过滤 AAR 本机库失败

Question

请帮我。我是 Mediapipe 的新手，正在尝试使用 Bazel 构建用于对象检测和框跟踪解决方案的 AAR。我收到这个错误。如何解决这个问题？我的操作系统是 Ubuntu 20.04，OpenCV 是 4.2。

我的构建命令：

sudo -s bazel build -c opt --strip=ALWAYS --host_crosstool_top=@bazel_tools//tools/cpp:toolchain --fat_apk_cpu=arm64-v8a,armeabi-v7a --sandbox_debug mediapipe/examples/android/src/java/ com/google/mediapipe/apps/tracking_aar:tracking_aar.aar

看起来错误是/usr/bin/env: 'python': No such file or directory

你的系统是否安装了python？python-is-python3安装软件包可能会有所帮助。
