无法在 nodejs 中导入 @tensorflow/tfjs-node [英] Cannot import @tensorflow/tfjs-node in nodejs

问题描述

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

Cannot import @tensorflow/tfjs-node into my program. I was trying to import it as follows:

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

But when i try to import @tensorflow/tfjs as

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

没有遇到错误.

我使用 npm as 安装了 @tensorflow/tfjs-node

I installed @tensorflow/tfjs-node using npm as

sudo npm install @tensorflow/tfjs-node

然后得到一个输出(如下):

Then got an output (follows):

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


node scripts/install.js

推荐答案

这里有两个问题.

以 root 身份安装软件包

您想以 root 身份安装依赖项，但 npm 默认不会以 root 身份运行.传递以下参数以启用root权限:

You want to install the dependencies as root but npm will not run as root by default. Pass the following arguments to enable root privileges:

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.

You should also reconsider using another (not root) to run your script.

Tensorflow.js 需要

tensorflow/tfjs-node 的 require 不会按照你的方式工作，包 @tensorflow/tfjs-node 不会导出任何东西，只是需要使用本机 C++ 绑定.

The require of tensorflow/tfjs-node will not work the way you do it, the package @tensorflow/tfjs-node will not export anything and is only required to use the native C++ bindings.

这是应该如何完成的(引用自教程):

Here is how it should be done (quote from the tutorial):

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