While running the dnn example for yolo I keep running into this error. Any reason why this is happening. I have made sure to include the namespace cv ,dnn, and std.

Sorry about that my mistake. So I am working with ros-OpenCV.Although I have installed the Debian package offered by Ubuntu.as for the language, I am trying to execute it in c++. Am I right to assume that I should try to install this from source, would that help in any case?

Sorry but ros-OpenCV. is off topics :

Keep in mind that this is a forum where we motivate people to go head on with their challenges. Basically the following types of questions are not allowed on this forum:

Questions about problems with openCV wrappers (EmguCV, JavaCV, OpenCVSharp, ...) or extension libraries (cvBlobsLib, opencvx, ...). Again these problems should be adressed to the proper fora.

try to build opencv without ros and run same yolo sample. yolo sample is dead in opencv 4 or opencv 3.4.7?
