https://github.com/spmallick/learnopencv/blob/master/ObjectDetection-YOLO/object_detection_yolo.py Does this code support opencv4? Why can't I detect any objects using opencv4 test yolov2?

Opencv is amazing, we can't see the implementation inside the function！ Or you can succeed with the following environment python3.6 opencv3.4.1 opencv-contrib3.4.1

I've finally managed to run the example with my configuration ( Opencv 4.1.1/ Python 2.7) !

Changes:

• scalefactor in cv.dnn.blobFromImage should be float, not integer
• replaced round() to int() for sizes

Here is the patch 1.txt Best wishes :)
