Bug描述 Describe the Bug

我从DOTA数据集中挑选个别图片作为新数据集，此前用PP-YOLOE-R能够正常训练，而现在用YOLOv5进行训练报错了。
训练命令为python -m paddle.distributed.launch tools/train.py -c configs/yolov5/yolov5_l_300e_coco.yml --eval --use_vdl True --vdl_log_dir output/yolov5_l_100e_dota/scalar

以下为报错内容:

我在PaddlePaddle/PaddleYOLO#131 中也进行了提问，对方回复PaddleYOLO不支持旋转框。请问想继续使用YOLOv5或YOLOX对旋转框数据集训练是要把数据集的标注文件改为水平框吗?有没有格式转换的参考文件呢?

我想问的是有没有旋转框标注转为水平框标注的参考文件，这个数据准备中好像没有相关内容?
