OpenOpt Installation

The page is obsolete, we have moved to openopt.org

1. If you have either problems with installation or bug reports you can use scipy-user mail list (this one is connected to scipy-user google group)

Note! If you have numpy.__version__ > 1.1, using OpenOpt from latest tarball or subversion repository is recommended.

2. Choose one of the following:

3. Ensure you have Python v. 2.4 or 2.5 and NumPy (ver. >= 1.1.0 is preferred, some users inform of errors due to v 1.0.5, 1.0.4 or even more obsolete) installed (as a rule, Linux systems already have Python installed, and "python-numpy" package is available in software channels, for example use "apt-get install python-numpy" or "aptitude install python-numpy" for Debian or *UBUNTU Linux).

  • Some Python distributions have no setuptools included, then you need either install it by yourself (for Linux users using software channels is recommended, for example "[sudo] aptitude install python-setuptools"; or, if any problems will be encountered, just add the directory containing "scikits" folder to your PYTHONPATH, hence further steps are not required).
  • Linux users, using software update channels to get numpy, as well as OpenOpt-related software (like cvxopt, setuptools, matplotlib, scipy, with all required and optional dependencies) can yield a little bit obsolete version, but could greatly economy your time and efforts.
  • Windows users may be interested in EPD ("Enthought Python Distribution") - it already includes numpy, scipy, matplotlib and much more.
  • Linux, Windows, Mac OS X users may be interested in SAGE (license: GPL) - "viable free open source alternative to Magma, Maple, Mathematica, and Matlab" - it contains Python + numpy + scipy + cvxopt + much more (BTW, 1/2 there is 0.5, not CPython- or C-like zero).
  • Python(x,y) is new Eclipse-based scientific Python distribution, currently available for Windows, but developers promise Linux and MacOS versions in future (check the site, mb it's already available).

4. Run installation:

  • Linux:
    [sudo] python setup.py install
    or
    [sudo] python setup.py develop
  • Windows: you should run setup.py and choose "install" option in menu.
  • You could also run setup.py from a filemanager (or python setup.py from terminal) and then chose option 2 (install) and (optional) change installation path to another (however, that one should be present in PYTHONPATH)

5. To ensure OpenOpt has been installed successfully you could run .../examples/nlp_1.py

Please mention it in OpenOpt guestbook and / or users page

Update OpenOpt

# type in scikits.openopt directory:
svn up .
[sudo] python setup.py install
# (or see the remark above about adding "scikits" folder to Python path)

Using docstrings

# type in Python interpreter:
from scikits.openopt import NLP, QP, NSP # etc
# and see help(NLP), help(QP), etc
# or see documentation online

Downloads

openopt.tar.bz2 contains latest changes (mentioned in newsline)
openopt0.15.tar.gz, openopt0.17.tar.gz, openopt0.18.tar.gz are stable releases
