FightingCV 代码库， 包含 Attention,Backbone, MLP, Re-parameter, Convolution
Hello，大家好，我是小马🚀🚀🚀
For 小白（Like Me）： 最近在读论文的时候会发现一个问题，有时候论文核心思想非常简单，核心代码可能也就十几行。但是打开作者release的源码时，却发现提出的模块嵌入到分类、检测、分割等任务框架中，导致代码比较冗余，对于特定任务框架不熟悉的我，很难找到核心代码，导致在论文和网络思想的理解上会有一定困难。
For 进阶者（Like You）： 如果把Conv、FC、RNN这些基本单元看做小的Lego积木，把Transformer、ResNet这些结构看成已经搭好的Lego城堡。那么本项目提供的模块就是一个个具有完整语义信息的Lego组件。让科研工作者们避免反复造轮子，只需思考如何利用这些“Lego组件”，搭建出更多绚烂多彩的作品。
For 大神（May Be Like You）： 能力有限，不喜轻喷！！！
For All： 本项目致力于实现一个既能让深度学习小白也能搞懂，又能服务科研和工业社区的代码库。
