Hello, I am trying to perform object detection using Yolov3 cfg and weights via readNetFromDarknet(cfg_file, weight_file) in opencv. I run into an opencv issue as the layer_type = 'shortcut' is missing from the opencv implementation of Yolov2. Unlike layer_type = 'route' in Yolov2, shortcut has linear activation as well. So, it cannot be simply replaced and opencv recompiled. Until the recent Yolov3 change trickles down to opencv, is there any possible workaround that anyone can think of? Thanks in advance!

Update: the yolov3 is now included [18/04/2018] in OpenCV, so make sure that you at least download a version that is past that point to have a working interface with YoloV3 models.

For more information, please refer to the raised and closed issue and the corresponding pull request.

please take the time, to explain the solution. a link to SO is not helpful at all.

I am not claiming that this is the solution. But as KlaimNod is trying to use yolov3 config/weights in opencv I think it is relevant that these are not supported as yet.

please understand though, that an outward link only never can be a valid answer here.
