javascript - BrainJS引用错误: brain is not defined

转载作者：行者123 更新时间：2023-12-01 00:27:21

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

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <script src="//unpkg.com/brain.js"></script>

    <script src="index.js"></script>

</head>
<body>

````

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]));
