Runner object can be built from config by ``runner = Runner. # Copyright (c) Open-MMLab. MMCV学习——基础篇2（Runner) Runner类是MMCV的一个核心组件，它是一个用来管理训练流程的引擎，并且支持用户用少量代码按照它提供的接口定制化修改训练流程。 下面博主按照官方Doc的思路再结合自己的理解讲解一下它。 Runner¶ The runner class is designed to manage the training. MMEval: A unified evaluation library for mmcv. 本文主要分析了 Runner 的作用、特性和具体实现，熟悉 Runner 部分对于理解 OpenMMLab 开源框架有很大帮助。 更好理解本文，可先阅读 MMCV 和 MMDetection 前系列解读文章。 def after_train_iter (self, runner): """Called after every training iter to evaluate the results. fileio, mmcv.
