5 years ago If you're sure that you used my fork of pyOpt it might be a bug that I haven't encountered yet. You could print out the relevant variables from pyOpt_gradient.py and check why there is a bool value where it shouldn't. Also the whole mpi code in pyOpt could be much improved, so you might first try to run it with a single process and see if that works ok.
@kjyv ,could you help me?When i run parallel_optimize_kuka_lwr4.sh,i got the following error.I'm almost get the solution,because it have runed 250 iterations(153 iterations for global optimizer,the rest for local).What's more, i run optimize_kuka_lwr4.sh could get well solution,not error. I use ubuntu 16.06 and python2.7,pyOpt from your readme.
