我新定义了一份数据集，来进行训练，在不到20epoch， eval出现出现 AP 和 AR全为0，请问怎么解决？ #1444

新数据集是和coco类似的，多加入了5个关键点，训练过程中 loss 和 acc_pose 是正常收敛的，但是在eval 时候，AP 和AR在上升0.19时，出现骤降，然后变成0。

建议优先检查一下
（1） label 标注是否准确
（2）configs/base/dataset/sport22.py 写的是不是对的

多训练一段时间再看看，会不会恢复回来。

@jin-s13 谢谢，但是这些已经进行了确认，才来向官方寻求帮助。这种情况非常奇怪！

(1) lable 已经检查，保证了标注和 configs/base/dataset/sport22.py关键点下标位置是一致的，调用cocoapi show_anns 图片显示人体关键点是正常的,确定了标注人体关键点的位置无误。
(2）模型已经训练到18epoch 发生骤降 22 epoch达到0，后面训练到40 epoch 仍然保持在0。

也同步试一下 res50 的模型吧~ 看看是不是模型的问题

@jin-s13 谢谢，我尝试了基于CNN的模型，它是正常工作的：loss逐渐收敛，AP 也是逐渐上升的，符合预期。

但是为什么会发生这种奇怪的情况呢？HRFormer 是针对coco的17个点来构造的吗？导致了其不适用与其他关键点数量，出现变成 AP 变成0 的情况

具体原理并不是特别清楚。只是经验上看，感觉transformer based 模型不是非常稳定。。。
HRFormer 理论上也并不局限于coco-17点。

感谢使用 mmpose 并提出 issue。我们会定时查看 issue 并及时回复或 assign 给相关的开发者。之后可以不必这样手动@用户，其中一些并非 mmpose 开发者。

新数据集是和coco类似的，多加入了5个关键点 ，训练过程中 loss 和 acc_pose 是正常收敛的，但是在eval 时候，AP 和AR在上升0.19时，出现骤降，然后变成0。
