Install PIP, Python, Tensorflow, OpenCV in Windows Easily

Today, we have the Quickest and Easiest way to Install PIP, Python, Tensorflow 2.0, OpenCV, and NumPy in Windows Easily without any third-party software. There are multiple ways to install Python, PIP, Tensorflow 2.0, OpenCV in Windows but here we are going to see the easiest to follow with steps and images for your reference.

Install Python In Windows-

Step 1– Download Python Web-based Installer or Python Executable Installer from Python.org. At the time of writing this article, the latest version of stable Python is Python 3.8.3. Even if the newer versions are stable while you are following these steps, the steps will be similar if not ditto.

I would recommend you to download the Python Executable Installer to install Python in Windows.

Step 2– Run the downloaded Python Executable Installer. You will be prompted with the Dialogue box for installation. Choose the “Install Now” option as it will be the easiest and fastest method.

IMP: Check both the options “Install Launcher for All Users” & “Add Python 3.8 to PATH”. The Path option will add Python to Environment variables so that you can run Python via Windows Command Prompt.

Step 3– Click on Install. The installation may take 30 secs to 2 mins depending on your System.

Step 4– Hopefully the installation would be successful and you will get another prompt with an option “Disable Path Length Limit”, I would recommend selecting that option and thereby removing the path length limit. It will potentially save you time in the future on debugging an avoidable issue and error like below:

error MSB3541: Files has invalid value "long\path\filename". The specified path, 
file name, or both are too long. The fully qualified file name must be less than 
260 characters, and the directory name must be less than 248 characters.

Step 5– Once you click on “Disable Path Length Limit”, You will be prompted with Successful setup box like below-

Install OpenCV & Numpy In Windows-

OpenCV (Open Source Computer Vision Library) is a Machine learning software library used for computer vision applications like face detection, face recognition, etc. This library is widely used for operations on images and videos.

There are multiple ways to install OpenCV but I will show you the simplest way to install using the Windows command prompt. You will need PIP installed successfully for this method.

Step 1- Open Windows Command Prompt

Step 2- Run the command pip install opencv-contrib-python

Step 3- The command will install the OpenCV and NumPy in your System. You will see the result as below-

Step 4- To verify the successful install of OpenCV, use the below commands in Windows Command Prompt-

1. python
2. import cv2
3. import numpy

If there are no errors while importing, you have successfully installed OpenCV and Numpy. For any additional libraries, use the command pip install <library_name>. This command will work for all the libraries except a few which will have a dependency on other libraries.
