Zero mAP when testing

[rkruegs123]

Similar to #671 I am getting all zeros for test results, but there is no answer as to why in that post. Like this previous post, it seems as though i am getting non-zero mAP from manual insepction and from the training loss.

Can anyone explain how they might have fixed it?

hey @rkruegs123 , any update on this? I too am facing this issue. The training loss decreases well, but when I run test_net.py I get 0 mAP for all classes

I met the same issue , have you solved it ?

Do your labels have space or upper cases? In pascal_voc.py, cls = self._class_to_ind[obj.find('name').text.lower().strip()] This code causes your labels mismatch to classes. Maybe you should modify 2 places:

1. self._classes = (...) Make sure classes are same as your labels.
2. cls = self._class_to_ind[obj.find('name').text]
