Error when building facemesh example on M1 mac about mediapipe HOT 6 OPEN

Change your opencv path in the .build file

from mediapipe.

What specific paths should be used?

Current WORKSPACE

new_local_repository(
    name = "macos_opencv",
    build_file = "@//third_party:opencv_macos.BUILD",
    # For local MacOS builds, the path should point to an opencv@3 installation.
    # If you edit the path here, you will also need to update the corresponding
    # prefix in "opencv_macos.BUILD".
    # path = "/usr/local",  # e.g. /usr/local/Cellar for HomeBrew
    path = "/opt/homebrew",
)

new_local_repository(
    name = "macos_ffmpeg",
    build_file = "@//third_party:ffmpeg_macos.BUILD",
    #path = "/usr/local/opt/ffmpeg",
    path = "/opt/homebrew/opt/ffmpeg",
)

No idea about MACOS OpenCV Path, but according to you err msg, the opencv header file is not found.

from mediapipe.

Is there a command-like way to find the OpenCV path?
OpenCV was included with Homebrew.

from mediapipe.

$ brew --prefix opencv
/opt/homebrew/opt/opencv

from mediapipe.

Hi @Nibosi0501,

To resolve the issue, please ensure that the path to OpenCV is added correctly in the Workspace. You need to do changes here:
https://github.com/google/mediapipe/blob/master/WORKSPACE#L382

and https://github.com/google/mediapipe/blob/master/WORKSPACE#L391.

If this still an issue, you can modify the path in the macos_opencv repository. Change the path to point to your Homebrew directory, specifically if it contains opencv@3 within the homebrew/opt directory. Avoid adding /opt/opencv@3 and also adjust the ffmpeg path to point to /opt/homebrew/opt/ffmpeg, as shown in the attached screenshot below.

Thank you!!
