Yep. The 6-DoF pose is another choice. But its searching space is larger than our keypoint choice. As for PnP, we used a non-differentiable version while you may want to...

Sorry about that. I have not tried it on Windows before. So it may not work. You can try some other backbone networks if needed.

Sorry. I have not tried CPU-only before. Maybe it has some trouble with DCNv2. You can try our provided weights with resnet instead.

> Thanks for adopting this code for multi-processing. Pytorch multi-processing requires a fixed dataset class, while in our case the dataset class is created dynamically [here](https://github.com/xingyizhou/CenterNet/blob/master/src/lib/datasets/dataset_factory.py#L32). A ugly but simple...
