IndexError with file from link

[h0uter]

after downloading yolo-obj.weights from the link in your README.md and running either of the examples I get the following error.

Traceback (most recent call last):
  File ".../DoorDetector/detection_image.py", line 89, in <module>
    outs = net.forward(get_output_layers(net))
                       ^^^^^^^^^^^^^^^^^^^^^^
  File ".../DoorDetector/detection_image.py", line 31, in get_output_layers
    output_layers = [layer_names[i[0] - 1] for i in net.getUnconnectedOutLayers()]

                                 ~^^^
IndexError: invalid index to scalar variable.

I tried opencv-python 3.4.18 and 4.8.1
