python - PyOpt packages not importing -


i have decided move current commercial optimization program pyopt.

i having difficulties importing optimizers struggling find information on pyopt other on pyopt home site.

the optimizers not importing: 

from pyopt import mmfd   #modiļ¬ed method of feasible directions                                              pyopt import mma    #method of moving asymptotes                                                                                               pyopt import gcmma  #globally convergent method of moving asymptotes                                                                  pyopt import nlpql  #non-linear programming quadratic lagrangian                                                            pyopt import nlpqlp #non-linear programming non-monotone , distributed search             pyopt import fsqp   #feasible sequential quadratic programming

the rest of optimizers import fine. running file below, packages seem installed, specific optimizers cannot imported.

i have suspicion ads (automated design synthesis optimization program), utilized in packages, not installed, cant find information on topic (seen source code of packages).

the software repeatedly installed on different machines same result, hence suspicion of missing packages in installer.

any pyopt user guidance appreciated.

we not use pyopt, use nlpqlp, appears on list of packages not imported.

nlpqlp not free, @ least not if 1 use.

it same mma me refers code produced svanberg @ kth.

based on this, pyopt contains interfaces packages not free.

i hope helps
