1. 下载安装

安装稳定版

pip install torch4keras

安装最新版

pip install git+https://github.com/Tongjilibo/torch4keras.git

2. 功能

  • 简述:抽象出来的Trainer,适用于一般神经网络的训练,仅需关注网络结构代码

  • 特色:进度条展示训练过程,自定义metric,自带Evaluator, Checkpoint, Tensorboard, Logger等Callback,也可自定义Callback

  • 初衷:前期功能是作为bert4torchrec4torch的Trainer

  • 训练:
