我知道您正在尝试在浏览器中加载模型，但是如果有人在这里尝试在Node中进行加载，方法如下:

I know you're trying to load your model in a browser but if anybody lands here that's trying to do it in Node, here's how:

const tf = require("@tensorflow/tfjs");
const tfn = require("@tensorflow/tfjs-node");
const handler = tfn.io.fileSystem("./path/to/your/model.json");
const model = await tf.loadModel(handler);
