Thank you. I have solved this problem._C.MODEL.ROI_BOX_HEAD.NUM_CLASSES = 22.
I gave it a wrong value.

I had five classes, I added + 1 on the defaults.py file _C.MODEL.ROI_BOX_HEAD.NUM_CLASSES = 6

That's probably because the category id is staring from 1 instead of 0. 0 <= category_id < NUM_CLASSES
