用yolov5训练自己的数据集时，发生如下错误。
if name == "main":
opt = parse_opt()
main(opt)

opt.project = str(ROOT / 'runs/evolve')
opt.exist_ok, opt.resume = opt.resume, False # pass resume to exist_ok and disable resume
opt.save_dir = str(increment_path(Path(opt.project) / opt.name, exist_ok=opt.exist_ok))

无
解决此问题
尝试过把相对路径改成绝对路径，并无效果，依然是以上错误。期待老师给出详细的解决方法。谢谢。
确定路径正确吗，你文件名前面是不是多个空格?
实在不行可以尝试换一个路径
路径改了就行
改成和yolov5同一级开始
比如
train: ..\piecedata\train\images
val: ..\piecedata\valid\images
下面是我的路径结构
