How to deal with triplet loss when at time of input I have only a json file of ID with 512 dimensonal vector?

Question

I have a file json with vectors generated from InsightFace with MXNet like this:

{"id": "huonght", "vector": "[-0.0591206625,-0.0562381446,...,0.0173285864,0.0403193906]}

{"id": "huonght", "vector": "[-0.0458422117,-0.0401753262,...,0.1048753187,0.0371856093]}

{"id": "huonght", "vector": "[-0.0422730967,-0.0223527066,...,0.0507882051,0.0381843373]}

...

How could I use Triplet Loss to generate these vector into clusters?
