如何使用c++在M1 mac上运行mediapipe

Question

环境

Macbook M1 2020。

大南方11.3.1

我想做什么

我想成功运行下面的"mediapipe c++ hello_world“。https://google.github.io/mediapipe/getting_started/install.html#installing-on-macos

我尝试了以下尝试，但失败了。

try1

做

只要遵循指导方针

https://google.github.io/mediapipe/getting_started/install.html#installing-on-macos

• 4. OpenCV和FFmpeg。=> I使用option1.

错误

在第6课中，我遇到了下面的一个错误。

// run lesson 6
mediapipe % bazel run --define MEDIAPIPE_DISABLE_GPU=1 \
    mediapipe/examples/desktop/hello_world:hello_world
2021/05/23 21:06:14 Downloading https://releases.bazel.build/3.7.2/release/bazel-3.7.2-darwin-arm64...
2021/05/23 21:06:16 could not download Bazel: HTTP GET https://releases.bazel.build/3.7.2/release/bazel-3.7.2-darwin-arm64 failed with error 404
mediapipe %

try2

“bazel-3.7.2-darwin-arm64 bug”说bazel试图从github版本下载try1。

但是，发行版3.7.2没有达尔文-arm64的类型。

https://github.com/bazelbuild/bazel/releases/tag/3.7.2

幸运的是，版本4.1.0的类型为达尔文-arm64 64。

https://github.com/bazelbuild/bazel/releases/tag/4.1.0

然后我尝试下载bazel-4.1.0-darwin-arm64.

做

在根存储库"mediapipe“中，将".bazelversion”文件修复如下。

4.1.0

然后，重试第6课，开始下载。

错误

但是下载没有成功:我得到了另一个bug，如下所示。

// run lesson 6 again
mediapipe % bazel run --define MEDIAPIPE_DISABLE_GPU=1 \
    mediapipe/examples/desktop/hello_world:hello_world

现在形势

然后我暂时放弃了，向你提问！

有人能解决这个问题吗？

提前谢谢。

Answer 1

我成功地构建了HelloWorld.cc精细。

我还在M1 MAC上编译了Android。NDK版本和权限有一些问题，但最终它编译并在我的S8 +上运行。

我的圈套

• MacBook Pro (13英寸，M1,2020)
• macOS Big Sur 11.5.1
• ndk版本: r20b (手动下载并编辑到ndk的工作区路径)

在第一次编译期间，您将得到许多权限错误问题，在构建过程中进入并保持打开状态>系统首选项>安全性和隐私>一般。

当出现错误时，允许继续并重新启动生成。在构建之前将获得大约8-10个权限。

下面的是构建过程的最后一部分.
