Darknet
Darknet is an open source neural network framework written in C and CUDA. It is fast, easy to install, and supports CPU and GPU computation.
This repository is borrowed heavily from https://github.com/pjreddie/darknet and https://github.com/AlexeyAB/darknet
new features
- shufflenetv2: channel_shuffle layer and channel_slice layer are added in this repo.
- yolov3 slimming: prune.cpp is added.
How to use
- shufflenev2: for example basic unit

yolov3 slimming
Support: yolov3-tiny, yolov3, yolov3-spp
./darknet prune ./cfg/yolov3.cfg ./cfg/yolov3.weights -rate 0.3
the pruned cfg/weights are saved as ./cfg/yolov3_prune.cfg ./cfg/yolov3_prune.weights
