could anyone check nlp_3.py from updated scikits.openopt?
Hi all, Nils Wagner informs me of a bug that I don't observe, so I can't fix the one. Could anyone update openopt from svn and run (after "sudo python setup.py install") examples/nlp_3.py ? (It works well for me) Thank you in advance, D.

I updated openopt from svn to rev. 896 and installed it with python setup.py install. Running the nlp_3.py script raises an exception suggesting that the solver ralg may not be installed. I'm not sure if I needed to do anything else with the install although I don't believe I had to previously.

Dave, could you update openopt from svn, run [sudo] python setup.py install and run nlp_3.py once again? (I made some changes so the bug will be described more precisely) Also, what's your Python version? Regards, D. Dave wrote:

That seem to have fixed the initial problem.
