Install Numpy and Open CV In ARCHLINUX BASE

 INSTALLATION OF NUMPY AND OPEN CV IN ARCH LINUX

Get Pyhton Set up

Ok, this one should be obvious, but you’ll need Python 3 installed.

Checking of pyhton version : $ pyhton --version

If you wanna install python : $ sudo pacman -S pyhton

Next, you will need to install VirtualEnv : $ sudo pacman -S python-virtualenv

This allow you to create virtual environments, which I highly recomended.

Create a Virtual Environment 

It’s incredibly easy to set up a python virtual environment in Arch. I’ll set up a folder named “cvtest”.

$ virtualenv cvtest

$ cd cvtest

$ source bin/activate

Now you have your environment set up, and you can use pip to install what you need.

Install some libraries

1. Installing package of numpy with command $ pip install numpy

2. Verify whether numpy is now part of your python package $ pip show numpy

3. To upgrade the numpy version $ pip install --upgrade numpy

4. Installing package of opencv with command $ pip install opencv-pyhton
