Yolov3 is implemened with pytorch 0.4 and python 3 modified from the marvis yolov2.
The marvis yolov2 is implemented on python2 and pytorch 0.3 environments.
Furrthermore, marvis didn't publish the yolov3 trainining implementation.
I modified some codes of marvis yolov2 and implemented yolov3 trainining modules.
