Cannot load model

[ngochai27595]

Dear author, I have face with this problem when try to do example const video = document.getElementById('largeVideo'); // const canvas = document.getElementById("canvas"); // const context = canvas.getContext("2d");

    // Load the model.
    handTrack.load().then(model => {
        // detect objects in the image.
        console.log("model loaded")
        model.detect(video).then(predictions => {
            console.log('Predictions: ', predictions);
            // model.renderPredictions(predictions, canvas, context, video);
            // requestAnimationFrame(runDetection);
        });
    });

--> "UnhandledError: Request to https://cdn.jsdelivr.net/npm/handtrackjs@latest/models/webmodel/centernet512fpn/base/model.json failed with status code 404. Please verify this URL points to the model JSON of the model to load" Could you help me. Thanks

Hi,

Thanks for pointing this out. Its a bug with the recent release that has experimental support for centernet models. I have fixed the bug in a new npm minor release but it may take a short amount of time to propagate to the jsdeliver cdn. In the mean time you can specify the ssd320fpnlite model when you load handtrack.js.

const defaultParams = { 
  modelType: "ssd320fpnlite"
};

handTrack.load(defaultParams).then(model => {
        // detect objects in the image.
        console.log("model loaded")
        model.detect(video).then(predictions => {
            console.log('Predictions: ', predictions); 
        });
});

Thank you. And I have one more question. Can I hand track realtime with an available live video?
