For CPU-based instalattion:
```
make install
```
For both CPU and GPU-based instalattion:
```
make install_gpu
```
Note: If you want to have GPU-acceleration before running command above install CUDA and cuDNN (Latest CUDA version I've tested is 10.2 and cuDNN is 7.6.5)

Installation

go get github.com/LdDl/go-darknet

Usage

Example Go program is provided in the example directory. Please refer to the code on how to use this Go package.

Building and running program:

Navigate to example folder

cd $GOPATH/github.com/LdDl/go-darknet/example

Download dataset (sample of image, coco.names, yolov4.cfg (or v3), yolov4.weights(or v3)).
```
#for yolo v4
./download_data.sh
#for yolo v3
./download_data_v3.sh
```
Note: you don't need coco.data file anymore, because sh-script above does insert coco.names into 'names' field in yolov4.cfg file (so AlexeyAB's fork can deal with it properly) So last rows in yolov4.cfg file will look like:
```
......
[yolo]
.....
iou_loss=ciou
nms_kind=greedynms
beta_nms=0.6

names = coco.names # this is path to coco.names file
```
Also do not forget change batch and subdivisions sizes from:
```
batch=64
subdivisions=8
```
to
```
batch=1
subdivisions=1
```
It will reduce amount of VRAM used for detector test.

Build and run program Yolo V4:

go build main.go && ./main --configFile=yolov4.cfg --weightsFile=yolov4.weights --imageFile=sample.jpg

Output should be something like this:

go-darknet: Go bindings for Darknet (Yolo V4, Yolo V3)

go-darknet is a Go package, which uses Cgo to enable Go applications to use YOLO V4/V3 in Darknet.

Since this repository https://github.com/gyonluks/go-darknet is no longer maintained I decided to move on and make little different bindings for Darknet.

This bindings aren't for official implementation but for AlexeyAB's fork.
