笔者data用到data.yaml,这个一般需要编写的多一点,注意nc和names数量一致即可。在使用时PATH试了好几回,相对路径的话他默认设置好像有些奇怪,容易像这样各种报: Dataset 'datasets/data.yaml' not found ⚠️, missing paths ['D:\code\datasets\ultralytics\datasets\dataset\valid\images'] 最后决定用绝对路...

check_dataset函数中,将训练集、验证集、测试集的路径拼凑出来,最后封装成一个Dictionary返回给data_dict变量,因此train_path, val_path就是完整的训练集和验证集目录。YOLOV5也是通过之前文章详细讲过的Dataset+DataLoader组合对数据进行加载和预处理。 第二步创建Dataset和DataLoader ...
PANet (Path Aggregation Network) 路径聚合网络, 通过添加自下而上的路径增强缩短了较低层和顶层之间的信息路径. 高层神经元反映了整个目标, 底层神经元反映了目标的基础信息. (a) 是 FPN (Feature Pyramid Networks) (b) 通过自下而上的捷径使得低层信息更好的向高层传播 ...
