Using brain.js in nodejs server but getting error gpu.js not present

问题

我使用brain.js库创建神经网络。
包已经安装完毕，但当我运行服务器时，我收到了以下错误消息。

找不到模块gpu.js

然后我安装了"npm i gpu.js"
然后我得到了以下错误 - 以下错误消息说要安装Visual Studio 2022的最新版本并在其中运行。我尝试了，但没有成功。

const trainingData = ytData.map((item, i) => ({

network.train(trainingData, { iterations: 2000 });

const outputData = network.run("Simple Machine Learning With JavaScript - Brain.js");

app.listen(PORT, () => {
  console.log(`Running up the hill at ${PORT}km/hr`);
});

任何帮助都将不胜感激。

this is how my code looks like 

code ->



import express from 'express';
import * as brain from 'brain.js/dist/index.js';
import dotenv from 'dotenv'
import  ytData  from './md/data.js';


dotenv.config()
const app = express()
const PORT = process.env.PORT || 8000


const network = new brain.recurrent.LSTM();

const trainingData = ytData.map((item,i)=>({
    input : item.title,
    output : item.views,
}))


network.train(trainingData,{iterations : 2000});

const outputData = network.run("Simple Machine Learning With JavaScript - Brain.js")


app.get('/',(req,res)=>{
    // res.json({message : `On this title you will probably get around ${outputData} views`})
    res.send("hello")
})



app.listen(PORT, ()=>{
    console.log(`Running up the hill at ${PORT}km/hr`)
})


**Any help will be appreciated.**

我经历过类似的问题。

为了解决它，我进行了以下操作：

1. 首先，我[使用了一个较旧版本的Node][1]，以解决`“npm ERR! code 1”`错误。不确定这部分是否与您相关，但我需要它：
   - 安装了`nvm`，然后运行：
   - `nvm install v15.14.0`
   - `nvm use v15.14.0`
2. 然后，我安装了一个较旧版本的`brain.js`，以解决`Cannot find module 'gpu.js'`错误：
   - 更新了`package.json`，使用了一个较旧版本：`"brain.js": "^1.6.1"`
   - 重新安装：`npm install brain.js`
   - 再次运行应用程序：`node index.js`

好的 - 希望这对您有帮助 :)

I experienced similar pain.

To resolve it, I did the following:

 1. First, I [used an older version of node][1], to resolve an `“npm ERR!
    code 1”` error. Not sure if this part is relevant for you, but I needed it:
       - [Installed][2] `nvm`, and then ran:
       - `nvm install v15.14.0`
       - `nvm use v15.14.0`
 2. Then, I installed an older version of `brain.js`, to resolve the `Cannot find module &#39;gpu.js&#39;` error:
       - Updated `package.json` with an older version: `&quot;brain.js&quot;: &quot;^1.6.1&quot;`
       - Re-installed: `npm install brain.js`
       - Ran the app again: `node index.js`

OK - hope that&#39;s helpful :)
