TypeError：无法在“ Window”上执行“ fetch”：在Tensorflow模型API上非法调用

Question

CocoSsd加载功能未在基于Node.js电子的应用程序上从Google加载API

 const unfetch = require('unfetch');
    const fetch = window.fetch.bind(window);
    const cocoSsd= require('@tensorflow-models/coco-ssd');
    const tfnode= require('@tensorflow/tfjs-node');
    const tf = require('@tensorflow/tfjs');
    async function loadModel(){  
const model = await cocoSsd.load();
const predictions =  await model.detect(img);
console.log('Predictions: ');
console.log(predictions);
}

path =“ https://storage.googleapis.com/tfjs-models/savedmodel/ssd_mobilenet_v1/model.json”，requestInits = {}
