Hello guys, I made an faster rcnn object detector but after 13 hours of training there is one class ( i have 5 classes at all) which has 0% average precision… this detector cannot detect this class on any image … what can be wrong?

Do you have enough of that class? If you didn't use many of that class in training, then perhaps it won't learn how to find it. How many images did you train with, and how many were in each of the 5 classes?

I don’t know the exact number of images for each class but i can say that there are most of images in class which has 0% of average precision… i trained with 790 images but i don’t know how much images are for each class..
