You can visit https://github.com/andy-yun/pytorch-0.4-yolov3 1.1k .
This reposository is forked from @marvis/pytorch-yolo2 and @marvis/pytorch-yolo3 .
But, I modified many files to support yolov3 training with pytorch 0.4 and python3.
I wish this repository could help your work.
There is also similar work at https://github.com/eriklindernoren/PyTorch-YOLOv3 616 .
