Install detectron2_backbone in three steps

It took a lot of effort to successfully install detectron2 on Windows before, but today I encountered the following error:

ModuleNotFoundError: No module named 'detectron2_backbone'

So install detectron2_backbone again

(1) Download detectron2_backbone

The download address is as follows:

https://github.com/sxhxliang/detectron2_backbone

（2）cd

(3) Installation

pip install -e .

Installing collected packages: addict, detectron2-backbone
  Running setup.py develop for detectron2-backbone
Successfully installed addict-2.4.0 detectron2-backbone-0.0.1

The installation was successful, and no other problems were encountered. It seems that the problems that should be solved when installing detectron before are basically solved.
The installation of detectron will be sorted out in the near future, mainly for some errors that may occur.
