Could not find type "type.googleapis.com/mediapipe.GateCalculatorOptions"

[jbest2015]

Hi Madeline, First thank you for taking the time to post this great example. I am trying to get it running, and have checked and double checked the changes.. it builds fine, but then I get this error trying to run it.
Any help would be much appreciated . I am running MacOs, Catalina 10.15.6. Proto is 3.6.1 .

This seems similar to MediaPipe Issue 650 and maybe also Issue 884.

Are you working with the multi-hand example? Do any of the MediaPipe examples run for you?

Hi , I have been continuing to work on it. I want to do the Multi hands in the future but for this, I tried to follow your instructions exactly. before I made any changes I was able to run all of the hand tracking models sucessfully. I wonder if is is related to the PROTOBUFF issue. In your document you stated that MediaPipe runs a different version of protobuf .. you mentioned something about a system wide installation.

Protobuf is backwards compatible, so there shouldn't be an issue there.

Sadly I don't have any definitive answers for you ... I would follow the suggestions in Issue 650: double check your OpenGL version and verify that your .pbtxt binary and graph targets match.

If you're tight on time, you can aways skip using wrapper_hand_tracking.proto, comment out any reference to it in my_pass_through_calculator.cc and just send your own custom formatted string.

For example, something like:

string landmark_list_msg;
for (int i = 0; i < landmarks.landmark_size(); ++i) {
    const NormalizedLandmark& landmark = landmarks.landmark(i);
    landmark_list_msg = "[" + std::to_string(i) + ",{" + std::to_string(landmark.x()) + "," + std::to_string(landmark.y()) + "," + std::to_string(landmark.z()) + "}],";
}

Thank you so much, I am going to give that a shot!
