Unable to execute object_detection

See original GitHub issue

As of rather recently I am unable to use object_detection, whereas everything else seems to work rather fine. It boils down to that error message:

Traceback (most recent call last):#################################################################################### |
  File "detector_mine.py", line 35, in <module>
    bbox, label, conf = cv.detect_common_objects(rect_img, confidence=0.75, enable_gpu=True')
  File "/home/user/.local/lib/python3.8/site-packages/cvlib/object_detection.py", line 135, in detect_common_objects
    outs = net.forward(get_output_layers(net))
  File "/home/user/.local/lib/python3.8/site-packages/cvlib/object_detection.py", line 29, in get_output_layers
    output_layers = [layer_names[i[0] - 1] for i in net.getUnconnectedOutLayers()]
  File "/home/user/.local/lib/python3.8/site-packages/cvlib/object_detection.py", line 29, in <listcomp>
    output_layers = [layer_names[i[0] - 1] for i in net.getUnconnectedOutLayers()]
IndexError: invalid index to scalar variable.

It runs fine on my old Win10/11 installation from a couple of months ago, however accessing the same script from a WSL machine on the exact same PC results in the error above. I’m also getting the same from a new macOS setup.

I think there are some changes in the latest OpenCV version. Try using with older opencv version for now. Will fix this soon.
