如何使用 Electron 运行 tensorflow.js？

Question

我无法使用电子运行 tensorflow.js，请帮助。

我有什么：
1. Windows 10 版本 1903
2.python 2.7
3.节点12.13.1
4. npm 6.13.1
5. node-pre-gyp 0.14.0，全局安装

我做了什么：
1. 来自 Electron 文档 (https://github.com/electron/electron-quick-start) 的克隆电子快速入门。
2. 运行 npm insntall 和 npm start 以确保一切正常。
3. 安装@tensorflow/tfjs-node:

npm install @tensorflow/tfjs-node

> @tensorflow/tfjs-node@1.4.0 install C:\Users\proxc\Desktop\electron-quick-start-master\node_modules\@tensorflow\tfjs-node 
> node scripts/install.js

4. preload.js中增加一行

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

5. 运行 npm start：

npm start

> electron-quick-start@1.0.0 start C:\Users\proxc\Desktop\electron-quick-start-master
> electron .

我尝试了什么：
1. 节点版本 13.3.0
2.npm rebuild @tensorflow/tfjs-node --build-from-source
3. 删除node_modules并再次运行脚本
4. 删除项目，重新开始

可能很有趣：
1、node_modules\@tensorflow\tfjs-node\lib不包含napi-4，但包含napi-5

Answer 1

在 Windows here 上构建 tfjs-node 似乎存在一个已知问题

解决方案是使用节点 10.16.3 并运行命令：

npm rebuild @tensorflow/tfjs-node --build-from-source
