The Swift project is just a totally new project and I have not added any codes to it. If I remove "//mediapipe/graphs/pose_tracking:pose_tracking_gpu_deps" and "@ios_opencv//:OpencvFramework", in deps, it will build successfully. But I need to use the pose tracking graph to implement the Pose function, so please help. Thanks!

Hi @trunghvbk,

Could you please outline the exact steps you are following, referencing the documentation? Additionally, kindly confirm the macOS version you are using—specifying whether it is based on the Silicon chip or Intel. This information will help us reproduce and better understand the issue on our end.

Thank you

trunghvbk commented 1 year ago

Hi @kuaashish The steps I'm following:

Pull the latest code from mediapipe repo: https://github.com/google/mediapipe
Create new folder: mediapipe/examples/ios/posetrackinggpuswift
Create a new iOS app project, copy all the file except .xcodeproj file into the folder created above
add BUILD file (attached on description)
Run bazel build command line: bazel build //mediapipe/examples/ios/posetrackinggpuswift:PoseTrackingGpuSwiftApp --ios_multi_cpus=arm64 --xcode_version=15.0

My Macbook is Macbook pro 2020 M1.

@kuaashish FYI this is the folder structure

schmidt-sebastian commented 1 year ago

Can you try building OpenCV from source? You can pass --define=OPENCV=source.

trunghvbk commented 1 year ago

Hi @schmidt-sebastian Thanks for your response I tried using the argument as you said but it appears the ERROR
