- download the model from 'https://pjreddie.com/darknet/yolo/' the name file is "yolov3.weights" move it or copy paste to folder 'yolo-coco' in yolo-object-detection-with-opencv project
- in 'yolo_video.py' there's a variable 'vs = cv2.VideoCapture(rt)' you can change the 'rt' to '0' for your webcam laptop or '1' to external webcam
- remember this is using CPU only not GPU because 'cv2.dnn.readNetFromDarknet' only support for CPU
- if you want to use GPU you can go to 'https://pjreddie.com/darknet/yolo/' and see the complete tutorial
- run 'python yolo_video.py' for windows and 'python3 yolo_video.py' for mac or linux
