Virtual Environments

To get started with virtual environments, simply download virtualenv using pip install virtualenv

Then do the following:

Initialization

1. Navigate to the folder you would like to work from
2. Run virtualenv demo_env where demo_env is what you would like to call the environment

Activation

1. Assuming you are in the folder where the virtualenv was intialized, run source demo_env/bin/activate to activate the environment

Now all the packages you install using pip will be local to this folder!

Deactivation

1. Type deactivate

Virtual Environments with iPython/Jupyter Notebooks

In order to make use of a virtual environment that you have created when running a Jupyter notebook:

1. Make sure that your virtual environment has been activated
2. Run ipython kernel install --user --name "demo_env" , where demo_env is the name of the environment you wish to use
3. In your Jupyter notebook, click Kernel -> Change Kernel and select your environment (in this example, demo_env), from the list.
