r3det-on-mmdetection R3det is not in the detector registry

Failed to train on R3Det* mmdetection version based on PyTorch. I got an import error when running sh rtools/train.sh

Traceback (most recent call last): File "tools/train.py", line 161, in main() File "tools/train.py", line 134, in main cfg.model, train_cfg=cfg.train_cfg, test_cfg=cfg.test_cfg) File "/home/xs/mtl/r3det-on-mmdetection-master/mmdetection-2.2.1/mmdet/models/builder.py", line 67, in build_detector return build(cfg, DETECTORS, dict(train_cfg=train_cfg, test_cfg=test_cfg)) File "/home/xs/mtl/r3det-on-mmdetection-master/mmdetection-2.2.1/mmdet/models/builder.py", line 32, in build return build_from_cfg(cfg, registry, default_args) File "/home/xs/.conda/envs/torch140/lib/python3.6/site-packages/mmcv/utils/registry.py", line 157, in build_from_cfg f'{obj_type} is not in the {registry.name} registry') KeyError: 'R3Det is not in the detector registry'

Besides, I install mmdetection from https://github.com/open-mmlab/mmdetection, because your setup.py installation failed in my device and I found the reason that mmdetection 2.2.1 is needed. So I guess my problem may caused by not using your setup.py?

My environment is : Pytorch: 1.4.0 Python: 3.6.10 CUDA: 10.0 GCC: 7.3.0
