PYSHELLSPEC is an advanced astrophysical tool for modeling of
binary systems with circumstellar matter (e.g. accretion disk, jet),
computation of interferometric observables |V^2|, arg T_3, |T_3|,
|dV|, arg dV, comparison of light curves, spectro-interferometry,
spectra and SED with observations, and both global and local optimisation
of system parameters. It is based on Shellspec, a 1-dimensional
LTE radiation transfer code by Budaj & Richards (2004).

For differential evolution, it was necessary to download:

  _differentialevolution.py

put it in:

  /usr/lib/python2.7/dist-packages/scipy/optimize/

and modify __init.py__:

  from ._differentialevolution import differential_evolution

Installation of several standard python modules was required:

  apt-get install python
  apt-get install python-matplotlib
  apt-get install python-numpy
  apt-get install python-scipy
  apt-get install python-nlopt
  apt-get install python-astropy

Alternatively, one can use:

  apt-get install python-pip
  pip install astropy
