There is nothing more annoying in a data science project than a library. That is incompatible with the Python Virtualenv Python Version you are using. Occasionally, all you need to do is set up a virtual environment with a different Python version.
First of all, I’m sorry to break it to you if you use Venv. Using venv to build a virtual environment for a different Python Virtualenv Python Version is not an easy task. You will need to install virtualenv because of this.
Today at Arzhost, here we discuss all versions of python in Windows and Linux. Why we need virtualenv, venv, and python activation.
What Distinguishes Venv and Virtualenv from One Another?
A library called venv is included with Python 3. In other words, setting up virtual environments doesn’t require the installation of a separate package. On the other side, you can obtain the virtualenv library using pip install virtualenv.
Additionally, according to the Arzhost team, venv is describing in the virtualenv documentation as Python Virtualenv Python Version.
Is slower (since it lacks the app-data seed method), less extensible. And unable to build virtual environments for arbitrary install versions of Python (and automatically find these). Unable to be upgraded through pip, and lacking in a comprehensive programmatic API (describe virtual environments without creating them).
Simulated Settings with Different Python Versions
The steps below must be followed to build a virtual environment using a different Python Virtualenv Python Version.
1: Download the necessary version of Python. Such as Python 3.6.
2: Download and run the Python program. A unique installation is what I advise. It doesn’t need to be add to PATH.
3: The Virtual Studio Code program (or any other editor or terminal). Windows Run it as an Administrator if the installation directory is located in Program Files.
4: Utilize pip to install virtualenv on your primary Python version. put virtualenv in
5: Use virtualenv to create the virtual environment and the -p argument.
Python
1 py -m virtualenv -p=<your_python_executable> <virtual_environment_directory>
If your directory contains spaces. Wrap it in double quotes. Like this:
Python
1 py -m virtualenv -p="C:\Program Files\Python36\python.Exe”. virtenv
Configuring Python Virtual Environments
The Python Virtual Environments system is a mechanism. To make sure that packages link to various projects are store in various locations. So that they do not conflict. A Python Virtual Environment is a separate environment from your other Python projects or environments that enables it to have independent dependencies.
1: Python Virtualenv Python Version in Window
Get start
1: Install Python
If you are on an ENGINEERING Windows Desktop, install Python 2.7 through the software center
2: Add Python to PATH
Navigate: Control Panel -> User Accounts -> Change my Environment Variables
Inside the top window labeled 'User Variables' select 'Path' and edit it
Select 'Browse' and navigate to C:\python27 and select 'ok'
Select 'Move Down' and repeat step 3 for C:\python27\Scripts
3: Open a new CMD prompt (Windows Key + R, cmd.exe
)
4: Install virtualenv through the command pip install virtualenv. If you are not an administrator do not update if prompted
5: Check that virtualenv is install through the command pip –version
6: Install VirtualEnvWrapper-win through the command pip install VirtualEnvWrapper-win
2: Python Virtualenv Python Version in Linux
Get start
1: Virtual Environments on Python 2.7
Create a virtual environment in your current directory for a project with the command: virtualenv my project
"my project" is whatever name you would like to give this environment
To create a virtual environment with a specific version of python use the command: virtualenv -p /usr/bin/python2.7 my project
"python2.7" can be replaced with the version you would like to use
2: Virtual Environments on Python 3.5+
Create a virtual environment in your current directory for a project with the command: python3 -m venv my project
"my project" is whatever name you would like to give this environment
Good luck!
