Indeed, The bug disappeared when I installed numpy 1.1.1 Thanks to Dmitrey. Eli On Mon, Aug 4, 2008 at 8:59 AM, Eli Brosh <ebrosh1@gmail.com> wrote:
Thank you Dmitrey, I downloaded the latest tarball (uploaded 08/04/08 00:54:17) and installed it. Before installing, I erased the older version from the site-packages. However, the ralg still crashes, at least under windows. I did not find the bug you mentioned in ralg_oo.py. Could it be that the bug is caused by my numpy version ? (on windows I use 1.04 that came with the enthought suite)
Thanks Eli

Hi Eli, It seems the bug was due to svn conflict changes (check your scikits/openopt/solvers/UkrOpt/ralg_oo.py, line 156, svn has put "<<<<<<< .mine" there). Try now latest tarball (or use download from subversion, the bug was absent there)
Another small request concerning OpenOpt. Is it possible to provide an example for use of scipy_tnc and scipy_lbfgsb from openopt ? Can these solvers work with linear equality constraints ?
Examples are absolutely same to nlp1, nlp2, nlp3, nlp_bench_1, nlp_bench_2 etc. But the solvers can use only lb<=x<=ub constraints. Regards, D.

Hello,
I encountered problems with the ralg solver in OpenOpt. the example nlp_3.py, supplied with the OpenOpt library crashed on two computers. On an ubuntu linux machine, the program simply stopped without further information. On a windows machine, with entought suite, there was a windows error message "pythonw caused a fatal error and it will be closed". The problem disappeared when I erased ralg from the solvers list. It did not occur with lincher and scipy_cobyla solvers. On both machines, the openopt installation was from the latest tarball (no more than week old).
What is the problem ? Can it be corrected ?
Thanks Eli
