Paddle.js 是百度 PaddlePaddle 的 web 方向子项目,是一个运行在浏览器中的开源深度学习框架。Paddle.js 可以加载提前训练好的 paddle 模型,或者将 paddle hub 中的模型通过 Paddle.js 的模型转换工具 paddlejs-converter 变成浏览器友好的模型进行在线推理预测使用。目前,Paddle.js 可以在支持 WebGL/WebGPU/WebAssembly 的浏览器中运行,也可以在百度小程序和微信小程序环境下运行。

浏览器/系统覆盖范围

  • PC浏览器: Chrome、Safari、Firefox
  • 手机浏览器: Baidu App、Safari、Chrome、UC and QQ Browser
  • 小程序: 百度小程序、微信小程序
  • 系统: MacOS、Windows

加载模型

  1. 支持加载网络模型文件和权重文件:
  • model.json (模型结构和算子属性)
  • chunk_x.dat (模型参数二进制数据文件)
  1. 支持加载模型对象
  • modelObj.model (模型结构 json 对象)
  • modelObj.params(模型参数,类型 Float32Array)

如果不想将模型放入网络时,可以使用方式二,直接将模型对象传入
