failed to install mmdet

I am following GETTING_STARTED.md to install mmskeleton, but at the step of python setup.py develop --mmdet, it occurs an error:

Then i go to mmdetection official repo and successfully install mmdetecion-2.6.0 :

git clone https://github.com/open-mmlab/mmdetection.git
cd mmdetection
pip install -r requirements/build.txt
python setup.py develop

I thought it would success, and i move on to next step python mmskl.py pose_demo, it occurs another error:

(base) weidawang@weidawang-TUF-Gaming-FX506LU-FX506LU:~/Repo/mmskeleton$ python mmskl.py pose_demo

ImportError: mmskeleton.utils.third_party attempted to use a functionality that requires module mmdet.apis, but it couldn't be loaded. Please install mmdet and retry.

Could anyone tell me how to solve it ? Thanks ！

The problem is caused by mmcv version, only mmcv==0.4.3 can work, and when you try pip install mmcv==0.4.3, then you must try python setup.py develop and python setup.py develop --mmdet again
