Virtual Environments

Virtual Environments

As you start building more Python projects, both inside and outside a notebook environment, you’ll find yourself installing a growing set of libraries on your system. This will eventually lead to problems such as not knowing which projects use which libraries and where different projects require different versions of the same library.

Creating a Virtual Environment

To create a virtual environment, go to the command line and select the directory where your project and the virtual environment will go.

Activating the Virtual Environment

To use the virtual environment you created, you must activate it using one of the activation scripts in your virtual environment’s support directory. There are different scripts for Windows and Unix-based systems like macOS and Linux.
