描述

With ref https://github.com/justadudewhohacks/face-api.js#face-recognition-by-matching-descriptors

I've managed to train the faces and and saving the dataset with JSON.stringify(labelledDescriptors) to a static JSON.

Is there a way to quickly load this dataset, or do I have to load the raw JSON and reinit the dataset with each new faceapi.LabeledFaceDescriptors(name, descriptors)?

Is there method such as

const labelledDescriptors = await faceapi.fetchDescriptors('/files/labeledDescriptors.json');
const faceMatcher = new faceapi.FaceMatcher(labelledDescriptors);

Pardon, if I didn't explain myself well. But the objective is to quickly loaded a saved labeledDescriptors for usage.

研究方向
The issue requests a utility function to load saved LabeledFaceDescriptors from JSON. Review the existing LabelledFaceDescriptors class and how it handles the descriptors array. Check if there are any existing serialization/deserialization methods in the codebase. The implementation would parse the JSON and create new LabelledFaceDescriptors instances. Consider adding a static method or a helper function. Also look at the issue comments for any design suggestions from maintainers. The contributor should also write tests and documentation.
