无法在 nodejs 中导入 @tensorflow/tfjs-node

Suh*_*ama 6 node.js tensorflow.js

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;
    ^

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 作为安装 @tensorflow/tfjs-node

sudo npm install @tensorflow/tfjs-node
Run Code Online (Sandbox Code Playgroud)

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

这里有两个问题。

以 root 身份安装软件包

您希望以 root 身份安装依赖项,但默认情况下 npm 不会以 root 身份运行。传递以下参数以启用 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(非 root)来运行您的脚本。

Tensorflow.js 需要

requiretensorflow/tfjs-node不会按照您的方式工作,该包@tensorflow/tfjs-node不会导出任何内容,仅需要使用本机 C++ 绑定。

这是应该如何完成的(引用自教程):

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