Hi Eli, please try to run example3.py from Linux OS terminal and inform what will output. As for numpy I remember error from 1.0.5 mentioned here http://openopt.blogspot.com/2008/06/numpy-related-bug.html but it was not triggered with ralg. Regards, D. Eli Brosh 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)
