AttributeError: module 'portalocker' has no attribute 'Lock'

Thanks for sharing your great work. I am sorry that I have a bug when I use python ./tools/train_net.py --num-gpus 1 --config-file ./configs/yolof_R_50_C5_1x.yaml

Bug log below as :

I woule be grateful if you could give me some advice. Thanks.

first pip uninstall portalocker and conda install portalocker then bug will be fixed.

另外有一个小地方，我觉得您可以考虑修改下 。 就是您建议安装的mish-cuda，好像不能够直接 build After git clone，you should movemish-cuda/external/CUDAApplyUtils.cuh to csrc/ before python setup.py build install
