I know that I could pip install opencv-python which installs opencv3, but is there a separate command or name for opencv specific version such as 2.4.9?
If you're a Windows user, opencv can be installed using pip, like this:
pip install opencv-python==
ex - pip install opencv-python==3.6
If you're a Linux user:
sudo apt-get install python-opencv
At the same time, opencv can be installed using conda like this...
conda install -c https://conda.binstar.org/menpo opencv=3.6
