2. What exact command you run: python -m pip install -e detectron2
   I don't konw why this problem appears and I use many methods to solve this problem but they do not work.

You've chosen to report an unexpected problem or bug. Unless you already know the root cause of it, please include details about it by filling the issue template.
The following information is missing: "Your Environment";

[CGL-learner]

cuda 11.3 pytorch1.11.0 python3.8.10

Even I was facing the same problem Below steps worked for me.

This is because detectron2 library has only wheels for <= Python 3.9."

Open a terminal or command prompt. Create a new environment called detectron2-env with the following command
conda create --name detectron2-env python==3.9 -y

Linux
conda activate detectron2-env

windows
activate detectron2-env

Install the dependencies

pip3 install torch torchvision torchaudio
git clone https://github.com/facebookresearch/detectron2.git
python -m pip install -e detectron2

please refer to the following documentation:
