如何在 Raspberry Pi 4 上安装和使用 mediapipe？

问题描述

我关注了官方 mediapipe 页面，但没有任何结果，所以有人可以帮助在 windows 中的 raspBerry pi 4 中安装 mediapipe 很容易安装和使用它，但在 raspBerry pi 等 arm 设备中我没有找到任何资源。

解决方法

我可以使用 Ubuntu 21.04 在 Raspberry Pi 4 (2gb) 上运行 Hello world cpu/gpu。 64 位。我还在搞手跟踪，但我会分享我的步骤。

安装 pip3：sudo apt install python3-pip 安装 Python 6 库：pip3 install --user six 安装 Go：sudo apt install golang-go 安装 Bazelisk：go get github.com/bazelbuild/bazelisk 将其复制到 bin：sudo mv ./go/bin/bazelisk /usr/bin/bazel 下载 Mediapipe：git clone https://github.com/google/mediapipe.git 安装 OpenCv：sudo bash ./mediapipe/setup_opencv.sh

下一步必须在WORKSPACE、opencv_linux.BUILD、ffmpeg_linux.BUILD中正确设置路径。

像这样：

媒体管道/工作区

new_local_repository(
    name = "linux_opencv",build_file = "@//third_party:opencv_linux.BUILD",path = "/usr/local",)

new_local_repository(
    name = "linux_ffmpeg",build_file = "@//third_party:ffmpeg_linux.BUILD",path = "/usr"
)

mediapipe/third_party/opencv_linux.BUILD

cc_library(
    name = "opencv",srcs = glob(
        [
            "lib/aarch64-linux-gnu/libopencv_core.so","lib/aarch64-linux-gnu/libopencv_calib3d.so","lib/aarch64-linux-gnu/libopencv_features2d.so","lib/aarch64-linux-gnu/libopencv_highgui.so","lib/aarch64-linux-gnu/libopencv_imgcodecs.so","lib/aarch64-linux-gnu/libopencv_imgproc.so","lib/aarch64-linux-gnu/libopencv_video.so","lib/aarch64-linux-gnu/libopencv_videoio.so",],),hdrs = glob([
        # For OpenCV 3.x
        #"include/opencv2/**/*.h*",# For OpenCV 4.x
         "include/opencv4/opencv2/**/*.h*",]),includes = [
        # For OpenCV 3.x
        #"include/",# For OpenCV 4.x
         "include/opencv4/",linkstatic = 1,visibility = ["//visibility:public"],)

mediapipe/third_party/ffmpeg_linux.BUILD

cc_library(
    name = "libffmpeg",srcs = glob(
        [
            "lib/aarch64-linux-gnu/libav*.so",hdrs = glob(["include/aarch64-linux-gnu/libav*/*.h"]),includes = ["include"],linkopts = [
        "-lavcodec","-lavformat","-lavutil",)

在此之后，您可以构建并运行 Hello world 应用程序。
