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:

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

然后得到一个输出(如下):

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
