mediapipe MacOS helloworld failure

I have this issue too.

It seems to be a compatibility issue between Mediapipe and OpenCV4.1.1 on macos.
The glog v0.4.0 installed by brew for OpenCV4.1.1 somehow is not compatible with the glog v0.3.5 used by MediaPipe.

We are working on a fix. For now, a temporary workaround could be

$ brew uninstall --ignore-dependencies glog
$ bazel clean --expunge
$ bazel run --define MEDIAPIPE_DISABLE_GPU=1 mediapipe/examples/desktop/hello_world:hello_world

In 785d266, we switched the default OpenCV version to 3.4.5 on macos.

You can do the following steps to switch the opencv dependency and rebuild the hello world example:

brew uninstall opencv
brew uninstall --ignore-dependencies glog
brew install opencv@3
git pull
bazel clean --expunge
export GLOG_logtostderr=1 && bazel run --define MEDIAPIPE_DISABLE_GPU=1 mediapipe/examples/desktop/hello_world:hello_world

me too on macos

We are closing this issue for now due to lack of activity. Please comment if this is still an issue for you.

FYI using opencv@3 on it's own didn't work for me. I still had to run brew uninstall --ignore-dependencies glog afterwards. I had never run brew install opencv (without the @ version qualifier)
