How to create virtual environment in python

In this tutorial, you will create a virtual environment to use in Python. `virtualenv` is a tool to create isolated Python environments in your personal environment. `virtualenv` creates a folder that contains all the necessary executables to use the modules that a Python project would need. Loading Python modules Start a FastX Type module avail and module load python/3.9.7 to load the Python module. Creating a Virtual Environment You will need the complete path to the Python executable for the version you want to use. Get Python executable path using the following command: virtualenv -p /gridapps/Python-3.9.7/bin/python ~/bigdata/test-venv A virtual environment is created. This is an isolated Python environment where you can install project-specific Python modules. You only need to create a virtual environment once per project. You can create as many as you would like for each new project, or even share environments if you want. Activating the Virtual environment Activate the virtual environment by navigating to it and running the following commands:

A Virtual Environment is a python environment, that is an isolated working copy of Python which allows you to work on a specific project without affecting other projects So basically it is a tool that enables multiple side-by-side installations of Python, one for each project. Creating virtual environment in Linux $ pip install virtualenv Now check your installation $ virtualenv --version Create a virtual environment now, $ virtualenv virtualenv_name After this command, a folder named virtualenv_name will be created. You can name anything to it. If you want to create a virtualenv for specific python version, type $ virtualenv -p /usr/bin/python3 virtualenv_name or $ virtualenv -p /usr/bin/python2.7 virtualenv_name Now at last we just need to activate it, using command $ source virtualenv_name/bin/activate Now you are in a Python virtual environment You can deactivate using $ deactivate Creating Python virtualenv in Windows If python is installed in your system, then pip comes in handy. So simple steps are: 1) Install virtualenv using > pip install virtualenv 2)Now in which ever directory you are, this line below will create a virtualenv there > virtualenv myenv And here also you can name it anything. 3) Now if you are same directory then type, > myenv\Scripts\activate You can explicitly specify your path too. Similarly like Linux you can deactivate it like $ deactivate

Configure a virtual environment PyCharm makes it possible to use the virtual environment. The main purpose of virtual environments is to manage settings and dependencies of a particular project regardless of other Python projects. virtualenv tool comes bundled with PyCharm, so the user doesn't need to install it. For Python 3.3+ the built-in venv module is used, instead of the third-party virtualenv utility. Create a virtualenv environment • Do one of the following: • Click the Add New Interpreter. • Press Ctrl+Alt+S to open Settings and go to Project: | Python Interpreter. Click the Add Interpreter link next to the list of the available interpreters. • Click the Interpreter Settings. Click the Add Interpreter link next to the list of the available interpreters. • Select Add Local Interpreter. • In the left-hand pane of the Add Python Interpreter dialog, select Virtualenv Environment. • The following actions depend on whether you want to create a new virtual environment or to use an existing one. New virtual environment • Specify the location of the new virtual environment in the Location field, or click and browse for the desired location in your file system. The directory for the new virtual environment should be empty. • Choose the base interpreter from the list, or click and find the desired Python executable in your file system. • Select the Inherit global site-packages checkbox if you want all packages installed in the global Python on your machine to be added to th...
