Python2 comes preinstalled on all featured images. This will change in the future as Python2 is deprecated and all operations for Jetstream will utilize or are utilizing Python3
Configurations settings appropriate and/or required for normal Jetstream operation have been put in place.
If you wish to reconfigure, reinstall, or upgrade Python, we recommend implementing a user-level virtual-environment technology,
such as VIRTUALENV, ANACONDA, or MINICONDA to avoid conflicts with the system-level installation.
If you do reinstall or modify Python or the related configuration settings or remove it from the system PATH, you may disrupt essential Jetstream features and MAY PREVENT SUCCESSFUL BOOTING AND CLOUD DEPLOYMENT.
Be aware that some PIP upgrades, even within Python2 or within Python3, particularly from pip9 to a higher version, require several additional steps to ensure continued instance operation or backward compatibility with installed software.
