@heromebius @silversl @erhahaha the accompanying repository works on MacOS, Windows and Linux, includes multigpu and multithreading, performs inference on images, videos, webcams, and an iOS app. It also tests to slightly higher mAPs than darknet, including on the latest YOLOv3-SPP.weights (60.7 COCO mAP), and offers the ability to train custom datasets from scratch to darknet performance, all using PyTorch :) https://github.com/ultralytics/yolov3

I think the error is simply a "file not found" error. Be sure that the video that you refer to , is really exist and its in the location that you have specified.

I also encountered this problem before. Later, I found that my video was misplaced. If you use -- video chicken.avi, be sure to put your chicken.avi under the same path of video_ demo.py, if your video file is in MP4 format, change it to -- video chicken.mp4
