模型剪枝是用在模型的一种优化技术,旨在减少神经网络中不必要的参数,从而降低模型的复杂性和计算负载,进一步提高模型的效率。 模型剪枝的流程:约束训练(constained training)、剪枝(prune)、回调训练(finetune) 本篇主要记录自己YOLOv8模型剪枝的全过程,主要参考

通过引入CVPR2023 PConv+BiLevelRoutingAttention思想,在钢铁缺陷中取得涨点,且相比较于发表的一些论文,创新新颖程度好很多,有需要自取可以在自己数据集进行实验,并很有可能发表论文成功哦!!! 5.源码获取 https://cv2023.blog.csdn.net/article/details/132790913 ...

基于DepGraph算法开发的PyTorch结构化剪枝框架 Torch-Pruning是一个结构化剪枝库,与现有框架(如torch.nn.utils.prune)最大区别在于,它会物理地移除参数,同时自动裁剪其他依赖层。 本课程在YOLOv8 v8.1版本代码的基础上增加DepGraph剪枝方法,在Windows和Ubuntu系统上演示针对自己的数据集训练和进行网络剪枝过程,并讲解Dep...
