Question

当我尝试运行代码时，我正在跟踪有关如何使用brain.js使用神经网络的教程，它为我提供了ReferenceError：未定义大脑，我已经通过npm安装并在HTML上安装了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

尝试添加显式协议https://，而不仅仅是使用//。当我这样做时，您的代码对我有用。

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]));
