Installing MediaPipe

Note: To interoperate with OpenCV, OpenCV 3.x and above are preferred. OpenCV 2.x currently works but interoperability support may be deprecated in the future.

Note: If you plan to use TensorFlow calculators and example apps, there is a known issue with gcc and g++ version 6.3 and 7.3. Please use other versions.

Choose your operating system:

Installing on Debian and Ubuntu
Installing on CentOS
Installing on macOS
Installing on Windows Subsystem for Linux (WSL)
Installing using Docker

To build and run Android apps:

Setting up Android SDK and NDK
Setting up Android Studio with MediaPipe

To build and run iOS apps:

Please see the separate iOS setup documentation.

Installing on Debian and Ubuntu

Checkout MediaPipe repository.

$ git clone https://github.com/google/mediapipe.git

# Change directory into MediaPipe root directory
$ cd mediapipe

Install Bazel (0.23 and above required).

Option 1. Use package manager tool to install the latest version of Bazel.
```
$ sudo apt-get install bazel

# Run 'bazel version' to check version of bazel installed
```
Option 2. Follow Bazel's documentation to install any version of Bazel manually.

Install OpenCV.

Option 1. Use package manager tool to install the pre-compiled OpenCV libraries.

Note: Debian 9 and Ubuntu 16.04 provide OpenCV 2.4.9. You may want to take option 2 or 3 to install OpenCV 3 or above.

$ sudo apt-get install libopencv-core-dev libopencv-highgui-dev \
                       libopencv-imgproc-dev libopencv-video-dev

Option 2. Run setup_opencv.sh to automatically build OpenCV from source and modify MediaPipe's OpenCV config.

Option 3. Follow OpenCV's documentation to manually build OpenCV from source code.

Note: You may need to modify WORKSAPCE and opencv_linux.BUILD to point MediaPipe to your own OpenCV libraries, e.g., if OpenCV 4 is installed in "/usr/local/", you need to update the "linux_opencv" new_local_repository rule in WORKSAPCE and "opencv" cc_library rule in opencv_linux.BUILD like the following:

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

cc_library(
  name = "opencv",
  srcs = glob(
      [
          "lib/libopencv_core.so*",
          "lib/libopencv_highgui.so*",
          "lib/libopencv_imgcodecs.so*",
          "lib/libopencv_imgproc.so*",
          "lib/libopencv_video.so*",
          "lib/libopencv_videoio.so*",

      ],
  ),
  hdrs = glob(["include/opencv4/**/*.h*"]),
  includes = ["include/opencv4/"],
  linkstatic = 1,
  visibility = ["//visibility:public"],
)

Run the Hello World desktop example.

$ export GLOG_logtostderr=1
# Need bazel flag 'MEDIAPIPE_DISABLE_GPU=1' as desktop GPU is currently not supported
$ bazel run --define MEDIAPIPE_DISABLE_GPU=1 \
    mediapipe/examples/desktop/hello_world:hello_world

# Should print:
# Hello World!
# Hello World!
# Hello World!
# Hello World!
# Hello World!
# Hello World!
# Hello World!
# Hello World!
# Hello World!
# Hello World!

Installing on CentOS

Checkout MediaPipe repository.

$ git clone https://github.com/google/mediapipe.git

# Change directory into MediaPipe root directory
$ cd mediapipe

Install Bazel (0.23 and above required).

Follow Bazel's documentation to install Bazel manually.

Install OpenCV.

Option 1. Use package manager tool to install the pre-compiled version.

Note: yum installs OpenCV 2.4.5, which may have an opencv/gstreamer issue.

$ sudo yum install opencv-devel

Option 2. Build OpenCV from source code.

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

cc_library(
  name = "opencv",
  srcs = glob(
      [
          "lib/libopencv_core.so*",
          "lib/libopencv_highgui.so*",
          "lib/libopencv_imgcodecs.so*",
          "lib/libopencv_imgproc.so*",
          "lib/libopencv_video.so*",
          "lib/libopencv_videoio.so*",

      ],
  ),
  hdrs = glob(["include/opencv4/**/*.h*"]),
  includes = ["include/opencv4/"],
  linkstatic = 1,
  visibility = ["//visibility:public"],
)

Run the Hello World desktop example.

$ export GLOG_logtostderr=1
# Need bazel flag 'MEDIAPIPE_DISABLE_GPU=1' as desktop GPU is currently not supported
$ bazel run --define MEDIAPIPE_DISABLE_GPU=1 \
    mediapipe/examples/desktop/hello_world:hello_world

# Should print:
# Hello World!
