问题描述

I'm trying to write a neural network using brain.js.我正在尝试使用 Brain.js 编写一个神经网络。 However, NodeJS doesn't allow me to do that neither with require('brain.js') nor with import 'brain.js' .但是，NodeJS 不允许我使用require('brain.js')或import 'brain.js' 。 Here is my code:这是我的代码：

const brain = require('brain.js')

const config = {
    iterations: 15000,
    log: true,
    logPeriod: 500,
    layers: [10]
}

const net = new brain.recurrent.LSTM()

const conjunctions = {
    0: 'Именительный',
    1: 'Родительный',
    2: 'Дательный',
    3: 'Винительный',
    4: 'Творительный',
    5: 'Предложный'
}

const inputData = [
    // some data for training
]

const test = 'Дельфина'

net.train(inputData)
const output = net.run(test)
console.log(`${conjunctions[output]} падеж`)

However, it shows me next error when running with require('brain.js') :但是，它在使用require('brain.js')运行时显示了下一个错误：

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module:         c:\Coding\Labs\Node.JS\MochaTest\node_modules\brain.js\src\index.js

} }

And next error when running with import * as brain from 'brain.js' :使用import * as brain from 'brain.js'运行时出现下一个错误：

    at ModuleJob.run (internal/modules/esm/module_job.js:109:37)
    at async Loader.import (internal/modules/esm/loader.js:133:24)

What should I do and how to import it right when using NodeJS 13.2.0?使用 NodeJS 13.2.0 时我应该怎么做以及如何正确导入它？ I have only brain.js and Mocha installed in this module.我在这个模块中只安装了 Brain.js 和 Mocha。

I'm trying to write a neural network using brain.js.我正在尝试使用brain.js编写神经网络。 However, NodeJS doesn't allow me to do that neither with require('brain.js') nor with import 'brain.js' .但是，NodeJS不允许我同时使用require('brain.js')或import 'brain.js'来做到这import 'brain.js' 。 Here is my code:这是我的代码：

const brain = require('brain.js')

const config = {

}

const inputData = [

brain js should be installed, you can do it with npm but remember that brain do have system dependencies, Usually people forget to install python (I don't know your system but a lot of server are "empty" when you start using them)应该安装brain js，你可以用npm来做，但记住brain确实有系统依赖，通常人们忘记安装python（我不知道你的系统，但是当你开始使用它们时很多服务器都是“空的”）
