Yolo Python interface does not detect any object #36

Hello. I need a python interface for yolo. Even my pre-trained model works well with the executable of yolo, any python interface cannot detect any object with the same weights. I used your python interface which is "yolo_opencv.py" and cannot detect any object again. I also tried to use "darknet_images.py" provided from original repository, but result is the same as I mentioned stackoverflow: https://stackoverflow.com/questions/64401460/yolo-darkent-images-py-cannot-detect-the-objects

How can I solve this problem? Thank you!
