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.

How to fix "Could not find a version that satisfies the requirement opencv-python"

I am trying to make some basic facial recognition with my raspberry pi using OpenCV-python, however, I am unable to install OpenCV-python using pip3.
I tried to follow this guide
https://pysource.com/2018/10/31/raspberry-pi-3-and-opencv-3-installation-tutorial/
once this didn't work I tried using a fresh os and upgrading python to no avail.
This is what happens when I input the pip3 command
pi#raspberrypi:~ $ pip3 install opencv-python
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Collecting opencv-python
ERROR: Could not find a version that satisfies the requirement opencv-python (from versions: none)
ERROR: No matching distribution found for opencv-python
I expect that opencv-python should start installing

Could not find a version that satisfies the requirement SoundRecognition

I want to install SoundRecongnition package but I'm getting the following error when I type: pip3 install SoundRecognition
"Could not find a version that satisfies the requirement SoundRecognition (from versions: )
No matching distribution found for SoundRecognition"
I tried upgrading the pip. Also tried using the --user tag but still facing the problem.
I'm using pip 19.0.3 version, python 3.7.0 version, and Pycharm as IDE.

ERROR: Could not find a version that satisfies the requirement speech_recognition (from versions: none)
ERROR: No matching distribution found for speech_recognition
just use
pip install SpeechRecognition

pip install SpeechRecognition
you just try above SpeechRecognition...i think sound recognition module not there in pip

There is no SoundRecongnition at PyPI (it is where from pip installs packages). What package do you mean? I cannot find it on the Net.
Do you mean SpeechRecognition?
pip install SpeechRecognition
