How to install Detectron2

I am installing layout-parser and following this link. Did not face any issues with the following packages.  

pip install layoutparser    
pip install "layoutparser[effdet]"    
pip install layoutparser torchvision     
pip install "layoutparser[paddledetection]"    
pip install "layoutparser[ocr]" 

But I am not able to install detectron2

pip install "git+https://github.com/facebookresearch/detectron2.git@v0.5#egg=detectron2" 

while installing this package I am getting this error    

> ERROR: Could not find a version that satisfies the requirement detectron2 (unavailable) (from versions: none)
>
> ERROR: No matching distribution found for detectron2 (unavailable)

I followed the same installation guide in Google collab and it worked but not able to install them in my Azure workspace.  

Check your python version. If you have Python version as 3.10 or higher you will face this issue. 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

Activate the environment with the following command:

Linux

conda activate detectron2-env

Windows

activate detectron2-env

Install the dependencies with the following commands:

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