Introduction: This workshop will introduce what Conda is and how it can be used to create a variety of environments, such as Python/R and contained applications.

Course Goals:

  1. Introduce Conda and what it is good for, and how to use on ARCC’s clusters.

  2. How to use Conda to create a variety of environments - based on Python, R and standalone applications.

  3. Detail some of the core Conda configurations that affect your environment.

Notes:

  • This workshop focuses purely on using Conda. We have a more advanced workshops that details the interplay between Python, Conda and Pip.

  • If you have existing Conda environments, or have installed your own version of Anaconda, then the examples within this workshop might provide different results.

  • We have tried to make the examples as generic as possible. You will need to replace <project-name> and <username> with appropriate values that apply to you.

This tutorial is available for download as a PDF here.
