I also encountered this problem, the mAP was always 0 in the process of training my data set.

I met the same issue , have you solved it ?

我是训练过程中mAP出现nan，这是什么问题呢？ Epoch 25/50 loss: [2.29048967][0][2.29048967][0] 1234/1234 [==============================] - 398s 323ms/step - loss: 3.6579.30782938][0][4.30782938][0]]] Epoch end eval mAP on weight logs/000/ep025-loss3.658.h5 Epoch 25 mAP nan
