node.js之无法在 nodejs 中导入 @tensorflow/tfjs-node

无法将 @tensorflow/tfjs-node 导入我的程序。
我试图按如下方式导入它:

const tf = require('@tensorflow/tfjs-node') 

并收到如下错误:

internal/modules/cjs/loader.js:638 
    throw err; 
    ^ 
 
Error: Cannot find module '/home/nama/working/Canvas-WEB/node_modules/@tensorflow/tfjs-node/lib/napi-v4/tfjs_binding.node'

    at tryModuleLoad (internal/modules/cjs/loader.js:593:12) 
    at Function.Module._load (internal/modules/cjs/loader.js:585:3) 

但是当我尝试将@tensorflow/tfjs 导入为

const tf = require('@tensorflow/tfjs') 

没有遇到错误。

我使用 npm 安装了@tensorflow/tfjs-node

sudo npm install @tensorflow/tfjs-node 

然后得到一个输出(如下):

@tensorflow/tfjs-node@1.2.7 install /home/nama/working/Canvas-WEB/node_modules/@tensorflow/tfjs-node 
 
 
node scripts/install.js

请您参考如下方法:

这里有两个问题。

以root身份安装包

您想以 root 身份安装依赖项，但默认情况下 npm 不会以 root 身份运行。通the following arguments启用 root 权限:

sudo npm install @tensorflow/tfjs-node --unsafe-perm=true --allow-root 

您还应该重新考虑使用另一个(不是 root)来运行您的脚本。

Tensorflow.js 需要
tensorflow/tfjs-node的要求|不会像你那样工作，包 @tensorflow/tfjs-node不会导出任何东西，只需要使用 native C++ 绑定(bind)。

这是应该如何完成的(引自 tutorial ):

const tf = require('@tensorflow/tfjs'); 
require('@tensorflow/tfjs-node');
