我正在遵循有关如何使用 Brain.js 处理神经网络的教程，当我尝试运行代码时，它给了我一个 ReferenceError: Brain is not Define 我已经通过 npm 安装并且在 HTML 上有 CDN。
const net = new brain.NeuralNetwork({ hiddenLayers: [3] });
const trainingData = [
{ input: [0, 0], output: [0] },
{ input: [0, 1], output: [1] },
{ input: [1, 0], output: [1] },
{ input: [1, 1], output: [0] }
];
net.train(trainingData);
console.log(net.run([0, 0]));
这是index.html

````
最佳答案
尝试添加显式协议(protocol) https:// 而不仅仅是使用 //。当我这样做时，你的代码对我有用。
const net = new brain.NeuralNetwork({ hiddenLayers: [3] });
const trainingData = [
{ input: [0, 0], output: [0] },
{ input: [0, 1], output: [1] },
{ input: [1, 0], output: [1] },
{ input: [1, 1], output: [0] }
];
net.train(trainingData);
console.log(net.run([0, 0]));<!DOCTYPE html>
