Error happened when convert pretrained darknet model

[Brokenwind]

When I convert pretrained darknet model with this command:

python3 convert_darknet_torch.py ~/model/darknet/darknet19_448.conv.23 -m model/name=model_voc model/dnn=model.yolo2.Darknet -d --copy ~/model/darknet/darknet19_448.conv.23.pth

error happened:
