what does the setup.py file do? about retinaface-tf2 HOT 3 CLOSED

The setup.py in the WiderFace-Evalutation/ folder is used to build the WiderFace-Evaluation package when we run
python setup.py build_ext --inplace
(see "evaluate on widerface" part of the ReadMe)

In general, for more information about setup.py files, you can check the officiel python packaging documentation : https://packaging.python.org/tutorials/packaging-projects/

from retinaface-tf2.

Sorry for my unclear question. I mean the setup.py in rcnn/cython which is used in Makefile. I think it is related to cpu or gpu devices. But why we write this part of codes? Does not the tf2 handle the devices automatically?

from retinaface-tf2.

The rcnn module is used to run non maximal suppression (or "nms") on the outputs of the neural network, which is in tf2.
Sometimes the neural network will output 2 boxes for 1 face. The nms step is here to find and delete duplicates.

So the setup.py is here to build this component on your machine. it builds a GPU version of nms, and also a CPU version if you dont have a gpu available. In this case you should change the "use_gpu_nms" of the RetinaFace object constructor.

Hope that clears it up !
