Tensorflow JS 和 Electron Forge - 在 npm 运行 make 之后导入 tensorflow js 时出错

Question

我用 tensorflow js 构建了这个小应用程序。我可以运行使用 npm start 在 Windows 10 上完美地运行，但是在我成功运行 npm run make 之后，就无法导入 tensorflow。我收到以下错误：

Uncaught Error: The specified module could not be found. \?\C:\Users\teste\AppData\Local\my-app\app-1.0.0\resources\app.asar.unpacked\node_modules\@tensorflow\tfjs-node\lib\napi-v5\tfjs_binding.node

当我转到 C:\Users\teste\AppData\Local\my-app\app-1.0.0\resources\app.asar.unpacked\node_modules\@tensorflow\tfjs-node\lib\napi-v5\tfjs_binding.node 时，文件就在那里并且可以完全访问

我运行宁windows10，节点v12.13.0，电子8.2.1与电子锻造

    ],
    packagerConfig:{asar:true}
}

感谢任何帮助

我刚刚找到解决方案。发生这种情况是因为 dll 需要与 buddings 位于同一文件夹中。错误消息非常具有误导性。

最后需要编写一些 post 安装脚本来将正确的 dll 复制到文件夹中并且它运行良好

Answer 2

刚刚仔细检查了您的代码 - 与您的文件夹结构有关。

如果我可能会问，你为什么使用 tensorflow.js 而不是 python 等？
