• Download the weights:

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

• Go to the directory:

cd darknet

• Run the detector (image):

./darknet detect cfg/yolov3.cfg yolov3.weights data/dog.jpg

• Run the detector (video):

./darknet detector demo cfg/coco.data cfg/yolov3.cfg yolov3.weights <video file>

• Run the detector (webcam):

./darknet detector demo cfg/coco.data cfg/yolov3.cfg yolov3.weights
