Process finished with exit code 1 请问这个是咋回事？，类别是1，数据集标注格式为cls,x1,y1,x2,y2,x3,y3,x4,y4,theta,x,y,w,h

[ccl-1]

数据集格式，x1,y1,x2,y2,x3,y3,x4,y4，x,y,w,h 都是原始坐标，没有进行归一化

我知道错在那里了，数据类别写错了，数据集里面的数据我把它映射到0，1，2这种形式了，换成原始字符串就能训练了。

我遇到了跟你一样的问题，但是我按你说的做了还是报错

@abaoji @ming71 @ccl-1 请问解决了吗，我把类别换成原始字符串还是报错。我的标签格式是class_name,x1,y1,x2,y2,x3,y3,x4,y4，是不是还需要加上theta，lx，ly，w，h，theta是相对于什么的角度,lxly是做左上角的坐标吗？
