Install Python and OpenCV on windows
My friend was asking me how to set up python environment since he had tried for a while but failed on his windows based enviroment. I have few experience though and all of the experence is based on Linux system. All I can recall are about the embedded porting for SAMBA application in which some codes relates to python and some material for cross-toolchain that scripts in python. So I spend some time to reference open course[1]
Here I note the steps for someone who needs as reference as well as for my friend.
Install Anaconda
Anaconda is a good start for rookie (like me) to avoid some conflictions on package installations. We can find the latest one on Anaconda and just clicking “next step” until installation sucessfully.After installation, we can open Anaconda Prompt with admin user.
Check the conda version
conda --version
# conda 4.5.11Under Anaconda Prompt, create an enviornment which is based on python 3.5.2.
conda create -n opencv_py352_demo python=3.5.2Check one of env you created, naming opencv_py352_demo
conda info --envs
# conda environments:
#
base C:\ProgramData\Anaconda3
opencv_py352_demo * C:\ProgramData\Anaconda3\envs\opencv_py352_demoIf you want to check all envs. and remove some of them, you can type:
conda remove --name myenv --all
conda env remove --name myenvIf you have generated opencv_py352_demo, you can activate directly
activate opencv_py352_demoInstall OpenCV
OpenCV, Spyder, SciPy and matplotlib
Spyder editor is strong IDE tools, and looks likes MATLAB env. If you are going to learn OpenCV, SciPy (pronounced “Sigh Pie”) and matplotlib are good combinations to do simulations on mathematics, science, engineering applications.
Install OpenCV
conda install -c https://conda.anaconda.org/menpo opencv3
conda install -c conda-forge opencvInstall spyder
conda install spyderInstall matplotlib
conda install matplotlibCheck all installed package
