Welcome to AstroConda Channel’s documentation!

AstroConda is a free Conda channel maintained by the Space Telescope Science Institute (STScI) in Baltimore, Maryland. This channel provides tools and utilities required to process and analyze data from the Hubble Space Telescope (HST), James Webb Space Telescope (JWST), and others.

System Requirements

  • 64-bit Intel/AMD processor (x86_64)
  • 64-bit Linux (glibc ≥ 2.12) or Mac OS X (≥ 10.7)
  • BASH or ZSH as your default shell environment (T/CSH is NOT supported)

Powered by Conda

Conda is an open-source software package management system provided and maintained by Continuum Analytics. Many software packages, provided both by Continuum and through third parties, are able to be quickly and easily installed using the Conda utility. AstroConda serves as a third-party add-on channel to provide easy access to STScI’s software packages.


Due to some currently missing python 3.7 Astroconda packages, the dependency solving process stalls for the package set that’s selected by running conda create without an explicit python version, since conda selects the most recent available by default, which is currently 3.7. To allow creation of new environments, for the time being specify a python version _other_ than 3.7 explicitly on the command line.:

$ conda create -n astroconda stsci python=3.6


If you are using conda 4.3.30 or older, please upgrade to the latest version before attempting to install or update any packages due to a bug in older versions that makes a large number of packages invisible and unable to be installed. Upgrading conda may require two steps. The following commands will allow you to verify that the upgrade was successful.:

$ source activate root
$ conda --version
conda 4.3.30

$ conda update conda $ conda –version

conda 4.3.31

$ conda update conda $ conda –version

conda 4.5.4 (Or whatever the latest version happens to be.)
