在使用mmrotate中的rotated_rtmdet旋转目标检测进行训练时出现的错误

Question

在使用mmrotate中的rotated_rtmdet进行训练时出现的错误，这可能是我数据集坐标或者旋转角度有问题吗?

这个错误提示表明在加载数据集时出现了索引错误，可能是由于数据集中的某些标注信息不完整或格式不正确导致的。具体原因需要根据数据集和代码的具体情况进行分析。建议检查一下数据集中的标注信息是否完整并且格式正确，例如是否缺少某些字段或者某些字段的值是否符合要求。同时也可以检查一下代码中对数据集的加载和处理部分是否存在问题。如果无法解决问题，建议向相关开发者或社区寻求帮助。
