Don't. Global names in Python are global to a single module, not your entire application. > I faced the problem with the pyomo modules but can generate the error with > pandas too. > > The model structure looks as follow: > > I have 3 '.py' files each of them containing definitions.

Note that only the first time a module is imported in an application the import may take a noticeable time. Subsequent imports result in a lookup in the sys.modules cache. > def optimization(x_l,y_l,z_l) > ...
