pytorch-yolo3

Convert https://pjreddie.com/darknet/yolo/ into pytorch. Currently this repository works on Python 3.6.1 + pytorch 0.4

This python3 version is merged from https://github.com/Swall0w/pytorch-yolo3 and https://github.com/marvis/pytorch-yolo3

Todos

  • Change train.py to enable Windows multiprocessing

Detection Using A Pre-Trained Model

wget https://pjreddie.com/media/files/yolov3.weights
