OpenCV Python Tutorial For Beginners 2 - How to Install OpenCV for Python on Windows 10
In this Articale on OpenCV Python Tutorial For Beginners, I am going to show How to Install OpenCV on Windows with Python.
Hey guys welcome in the next Article
on openCV tutorials for beginners using Python.
in this article I'm going
to show you how
you can install OpenCV for python on your
Windows operating system.
So obviously you
need to install Python on your Windows
operating system in order to install OpenCV
for python.
So first of all I'm going to show you how you can install Python on your Windows operating system and then we will see how to install OpenCV using Python now if you have already installed Python on your Windows operating system you can skip about five minutes and go directly to the point where I am going to show you how you can install OpenCV for python.
so let's get started so first of all
open your favorite browser on your Windows 10
operating system and then search for Python and the first link which will appear here will be from python.org e so we are going to click on that link and once this Python Waddy website is open you just need to scroll down a little until you see this downloads section and you can see at the time of making this Image python 3.7.0 is the latest version of python available.
so we are going to click on this link which
says python 3.7.0 and you will be redirected to this page which says python
3.7.0 and now i'm going to scroll down until i
see the files here and you will see there are
various kinds of installer available here we are going to install the python using the executable installer.
so we are going to choose this option which says windows x86 - 64 .executable installer and now I will wait for this executable to be downloaded and once this executable is downloaded you just need to click on this Exe file and I'm going to minimize the browser here.
so you can see pythons 3.7.0 setup
window has been started and on the first
window you will see two options here one is
Install Now and other is customized installation so what we are going to choose
is this option which says customize installation because when you choose this
Install Now option we'll be installed at this part which I don't want to use
you can see it's a long path which I don't want to remember so I will use this
option which says customize installation and I will also check this option
which says add Python 3.72 path.
so now let's click on customize
installation and next you will see this optional feature window and you can see
there are some optional feature which this Python installer will install.
for example
documentation pip it will install which is a Python package manager Idol IDE
Python test suit and other feature it's going to install so I'm going to leave
everything as default.
and then I'm going to
click Next and now this next window will open which says advanced option here
I'm going to check this option which says install for all users and I'm going
to leave other checkboxes as checked and then you will see this section here
which says customize install location
so I want to install Python
on my C directory so what I'm going to do is I'm going to open the Windows
Explorer and I'm going to go to the C directory here and once the C directory
is open I'm going to right click here and I'm going to create a new directory.
and I'm going to name
this a directory as Python and then I'm going to press enter and this part I'm
going to give here in the customize install location.
so I'm going to just
give this part which says C colon slash Python and then backslash Python 3 7 3
7 here means that we are going to install 3.7 version of Python.
so now python will be installed at this location
on my computer and then i'm going to click on the install button here.
.
and then you will see
the installation will start and it will be finished in a few seconds so just
wait for the installation to complete and after some time i can see this
message which say setup was successful.
so i'm going to click on
this close button which is going to close this installer
so now in order to check whether
python is installed on our windows operating system
or not we are going to search for python here and you will see a few options
here one is this python 3.7 terminal other is idle so first of all we are going
to click on this option which says Python 3.7 64-bit which is going to open
this kind of terminal.
so this is a Python terminal and here we can
for example print something so I'm going to just write print and in the
parenthesis and in between the double quotes I can just write hello world and then press Enter which
is going to in return print hello world that means Python 3.7 terminal is working.
so I'm going to close
this terminal now and once again I'm going to search for Python here and this
time I'm going to select this option which says idle ok so just select this
option which says idle and in the parenthesis Python 3.7 64 bit
so this idle is an IDE
which comes with Python installation at the time of installation we have chosen
this option to install idle that's why we can see this option here and also
this is an interactive shell so you can once again write a print and inside the
parentheses you can just write for example once again hello world and then press ENTER and it's
going to give you this kind of output here so now python interactive shell is working
and idle ide is also working so I'm going to close this idle IDE
now I want to check
whether Python is working using my command prompt or not
so I'm going to right
click on this Windows button and then I'm going to click on command prompt and
here I'm going to first of all write Python and then press ENTER and you can
see this python option is working now even on your command prompt right so here
also you can just write print and inside the parenthesis you can just print
hello world and then press ENTER and
it prints hello world in return
now one python is
installed on your Windows 10 operating system we are going to install OpenCV
using pip now pip is automatically installed on your Windows operating system
with the Python installation
so you don't need to separately
install pip on your Windows operating system it comes automatically with your
Python installation
so to verify this first of all I'm going to
check the python version so you can just give this command python - - version
and then you can check the pip version so you can just give this command pip -
- version so just give this command and it's going to give you the version of pip
which is installed on your Windows operating system
so to install OpenCV using pips you just need
to give this command pip install open CV - Python and I'm going to press ENTER
so you can see open CV related packages are downloading now so now open CV
Python package is installed using pip on my Windows operating system
now you will observe one more thing here and
that is numpy package will be automatically installed with your OpenCV python
package
so now once open CV
python package is installed we can verify it by just opening our Python shell
so I'm going to just give python command to open the Python shell and then here
I'm going to just write import CV - okay so once you give this command it
should not give you any error and if this import gives you error that means
open CV is not correctly installed on your operating
now after importing you
can just check the version of open CV which you have installed using C v2 dot
underscore underscore version underscore underscore and then press ENTER and
it's going to give you the version of open CV which is installed on your opera system
and in our case this is for point zero point zero at the time of making this
article
Now you can check the same by writing your
code inside a Python file also so here I have opened my Visual Studio code
editor and I have already created sample dot py file and here also I'm going to
import the CV to package first of all and then I'm going to print the version
of CV to using this print statement so I'm going to just write C v2 dot
underscore underscore version underscore underscore and then save this script and
to open the terminal inside Visual Studio code you can just press control shift
P and then type toggle integrated terminal so just type toggle integrated
terminal and then click on this first option which says toggle integrated
terminal this is going to open the terminal inside your Visual Studio code
editor so here you can run your python script using the python command so
python and then name of the script which is sample dot py in my case and then
press enter and it's also going to give you the version of OpenCV which is
installed on your operating system so this is how you can install OpenCV for python
on your Windows operating system I hope you've enjoyed this article .
And I will
see you in the next Article
