How to install pyacs?


pyacs is written in python. Since 2018, pyacs has moved to python 3.6.

I recommend to install first a Scientific Python Package like Anaconda or Enthought, which comes with all required libraries installed.

Getting the software

Check the latest release here


Installation should be straightforward if you have Anaconda installed. For a tar bz2 ball pyacs.X.tar.bz2, just type

pip install pyacs.X.tar.bz2

Anaconda pip program should install all required packages first and then install pyacs components.

You can uninstall pyacs any time by typing

pip uninstall pyacs

Setting your environment

  • First, check that env python properly launches python

  • Check that env ipython properly launches ipython

  • verify that Numpy, Scipy and Matplotlib can properly be imported

In your .bashrc or .bash_profile, or .cshrc depending on your environment , add (example for a bash environment)

alias ipyacs='ipython `which` -i'

Once done, source you configuration file, or open a new terminal window. Check pyacs is working


should return something like

Additional software

Some additional software are useful to work with PYACS and visualize results

  • GMT

  • Qgis


Sgts.show_map(tile=True) requires cartopy 0.18.0 which does not import properly. Use:

CFLAGS='-stdlib=libc++' pip install cartopy --upgrade
