Example Go application using go-darknet

This is an example Go application which uses go-darknet.

Run

Navigate to example folder:

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

Download dataset (sample of image, coco.names, yolov3.cfg, yolov3.weights).

./download_data_v3.sh

Note: you don't need coco.data file anymore, because script below does insert coco.names into 'names' filed in yolov3.cfg file (so AlexeyAB's fork can deal with it properly) So last rows in yolov3.cfg file will look like:

......
[yolo]
mask = 0,1,2
anchors = 10,13,  16,30,  33,23,  30,61,  62,45,  59,119,  116,90,  156,198,  373,326
classes=80
num=9
jitter=.3
ignore_thresh = .7
truth_thresh = 1
random=1
names = coco.names # this is path to coco.names file

Build and run program

go build main.go && ./main --configFile=yolov3.cfg --weightsFile=yolov3.weights --imageFile=sample.jpg
