即使所有标注都是唯一的，YOLOv5也会抛出重复标注错误

Question

我正在尝试使用YOLOv5x构建一个对象检测系统。我通过Roboflow网站创建了我的数据集，将其下载到我的笔记本后，我运行以下命令开始训练：

!curl -L "https://app.roboflow.com/ds/[DATASET-LINK]" > roboflow.zip; unzip roboflow.zip; rm roboflow.zip

但我得到的每一张图片都有这个错误：

它抱怨“重复标签”，但我不知道这是什么意思。我没有两个相同的类，这个数据集在YOLOv4和YOLOv4-Tiny上工作得很好。

Answer 1

我在使用yolov5时也遇到了这个问题。它主要发生在数据预处理期间。我发现的原因是，正如提示所说，标签是重复的。在txt标记文件中，标签的位置重复。如下所示，标签被复制了四次。如果只有一次，问题就会消失。enter image description here
