How to exclude the head part from evaluation #312

Hello, and thank you for this fantastic project. In my current project, I need to remove the head part detection from the evaluation framework; how could I do this? I mean, it is possible to modify the eval.py script such that the given mAPs correspond only to the precision of the body parts detection (no head detection)? Would you please give me any guidance on this matter? I really appreciate any help you can provide.
