I am running Ipopt in a loop (from Python > Cyipopt).
Is there a way to suppress the following startup message for Ipopt?
This program contains Ipopt, a library for large-scale nonlinear optimization. Ipopt is released as open source code under the Eclipse Public License (EPL). For more information visit http://projects.coin-or.org/Ipopt
I have already set print_level = 0 and passing it as an Ipopt option, but I am still getting the startup message.
I also tried passing as an option from Python using nlp.addOption('sb','yes'), but getting the following error message:
File "src/cyipopt.pyx", line 425, in cyipopt.problem.addOption
TypeError: Invalid option type
(See link: https://groups.google.com/forum/#!topic/julia-opt/TVmuXFWfeBM for the above possible solution.)
I have found another possible solution posted a while ago at https://list.coin-or.org/pipermail/ipopt/2013-September/003510.html but don't understand where and how to implement it.
Thanks.
