xcode – PoseLandmarker iOS Instance

I am attempting to create a library wrapper for the MediaPipeTasksVision.framework in xcode, the wrapper is for a programming language known as B4X which is a cross platform programming language and it is syntax is just like Fundamental, I’ve created many different wrappers earlier than for the B4X group, nonetheless I’m having some points when implementing the wrapper for MediaPipeTasksVision.framework in a B4X challenge, I assumed I would submit right here to get your knowledgeable advise on a difficulty I’m having.

I’ve a small B4i challenge simply to check the library wrapper however I’m seeing the next Errors when working the challenge.

NOT_FOUND: ValidatedGraphConfig Initialization failed.
No registered object with identify: mediapipe::duties::imaginative and prescient::pose_landmarker::PoseLandmarkerGraph; Unable to seek out Calculator “mediapipe.duties.imaginative and prescient.pose_landmarker.PoseLandmarkerGraph”

I do know the .job file is being discovered based on the next logs

Mannequin path: /personal/var/containers/Bundle/Utility/B773963F-D4D6-438E-BAF6-FA0911F44C6F/tros.ai.app/pose_landmarker_heavy.job

I’ve all the required referenced libraries included in my challenge however can not seem to discover why I’m seeing that error, here is the code the place the MPPPoseLandmarkerOptions are being initialized in my library wrapper.

`- (MPPPoseLandmarker *)createOptions: (NSString *)tasfilePath :(float)minPoseDetectionConfidence :(float)minPosePresenceConfidence :(float)minTrackingConfidence{
    NSError *optionsError = nil;
    NSString *modelPath = [[NSBundle mainBundle] pathForResource:tasfilePath ofType:@"job"];
    
    if (!modelPath) {
        NSLog(@"Error: .job file not present in DirAssets.");
    } else {
        NSLog(@"Mannequin path: %@", modelPath);
    }
    
    
    MPPPoseLandmarkerOptions *choices = [[MPPPoseLandmarkerOptions alloc] init];
    choices.baseOptions.modelAssetPath = modelPath;
    choices.baseOptions.delegate = 0;
    choices.runningMode = MPPRunningModeImage;
    choices.minPoseDetectionConfidence = minPoseDetectionConfidence;
    choices.minPosePresenceConfidence = minPosePresenceConfidence;
    choices.minTrackingConfidence = minTrackingConfidence;
    choices.shouldOutputSegmentationMasks = false;
    choices.numPoses = 1;

    MPPPoseLandmarker *landmarker = [[MPPPoseLandmarker alloc] initWithOptions:choices error:&optionsError];

    if (optionsError){
        NSLog(@"optionsError: %@", optionsError.localizedDescription);
    }
    return landmarker;
    
    
}`

I am hoping I can get some perception from somebody right here, I’ve been engaged on this for nearly per week now however cannot discover why this error is going on, earlier than anybody jumps on my throat, I’m not asking for assistance on how B4X is meant to work, I’m searching for assist in particularly in regards to the MediaPipe framework and the MediaPipeTasksVision framework, thanks upfront for any advise or tips about what to test.

I’ve made certain all of the dependencies are linked in my library, I’ve made certain the .job file is just not corrupted, and likewise made certain the graph file is within the challenge, the identify of the graph file is MediaPipeTasksCommon_device_graph.a and additionally it is being discovered, if I take away the reference to this file then my challenge would not compile and it complains about this particular file.

As I discussed, the B4X/B4i challenge compiles simply nice on my system however when i initialize the BaseOptions half that is after I see the error.
