python head_detection_demo.py --img_path /home/fwq/pic/1.png --model_path /home/fwq/zhanghongruils/head/fchd/model/head_detector_final

info:
the python code for non_maximum_suppression is about 2x slow
It is strongly recommended to build cython code:
cd model/utils/nms/; python3 build.py build_ext --inplace cd model/utils/nms/; python3 build.py build_ext --inplace''')
Setting up a new session...
