Conda Python Environments

CMS maintain an Anaconda Python environment at NCI, with a wide variety of climate and weather related libraries.

You can find the most recent list of libraries at our github repository, or run conda list with an environment loaded.

To use any of the conda environments you must first run

module use /g/data3/hh5/public/modules

You can safely put this in your ~/.bashrc file

Stable Environment

We update the stable environment once a quarter, around when NCI do their quarterly maintenance of Raijin. Otherwise everything in the environment stays fixed, we don't update packages or install new packages unless something is very broken.

module load conda/analysis3

Unstable Environment

The unstable environment gets updated more often, as we install new packages or apply updates to existing ones. If you ask for a new package it will be installed here.

module load conda/analysis3-unstable

When we do our quarterly update the unstable environment becomes the new stable environment.

Interactive Analysis / Jupyter

For interactive analysis we encourage making use of NCI's VDI system, which allows you to run Jupyter notebooks without waiting in the queue

Requesting new packages

You can ask for a new package to be installed or for an existing package to be updated by emailing
