GWpySoft is the stack of software includingGWpy,GWSumm andGWpy-VET, and all dependencies (criticallynumpy,scipy,astropy, andmatplotlib).

This repository provides simple scripts to set up avirtualenv containing those packages, mainly for use on the LIGO Data Grid.

To install the stack, first clone the repository

git clone https://github.com/gwpy/gwpysoftcd gwpysoft

then run thegwpysoft-init script to generate a new virtualenv

./gwpysoft-init<target-dir> ./packages.txt

The first argument (<target-dir>, e.g.${HOME}/opt/gwpysoft) is the target directory for the virtualenv, and can be anywhere you want.The second argument (./packages.txt) is a plaintext file containing the list of packages you want; the format is that of apip requirements file.

Then the virtualenv can be activated by

. <target-dir>/bin/activate

Thegwpysoft-init script will also try to install the matplotlibbasemap toolkit (only if matplotlib itself was installed).This is mainly because if you install a custom version of numpy (which in general will be true), basemap needsgeos to be recompiled against it.

If you have an installation of the Intel MKL (i.e. ificc is on thePATH),gwpysoft-init will try to build MKL-compiled versions of numpy and scipy.These will be installed under<target-dir>-mkl (e.g.${HOME}/opt/gwpysoft-mkl) and a bash environment script will be installed under<target-dir>-mkl/etc.
