\nT\u00eb tre paketat ekzistojn\u00eb n\u00eb depozit\u00ebn e Python-it, prandaj i instalojm\u00eb ato me pip.<\/p>\n

\u00c7do nj\u00ebri prej tyre ka nd\u00ebrfaqen e vet, dhe or-tools u zgjodh pik\u00ebrisht p\u00ebr t\u00eb provuar paketa t\u00eb ndryshme, pa pasur nevoj\u00eb p\u00ebr t\u00eb ripar\u00eb programin n\u00eb m\u00ebnyr\u00eb t\u00eb konsiderueshme, prandaj detyra \u00ebsht\u00eb q\u00eb or-tools t\u00eb lidh\u00eb k\u00ebta zgjidh\u00ebs dhe t\u00eb mund\u00ebsoj\u00eb q\u00eb ata t\u00eb kompakt\u00ebsohen.

K\u00ebshtu q\u00eb, duhet t\u00eb shohim se \u00e7far\u00eb shkruhet n\u00eb dokumentacionin<\/a><\/noindex>.

E vet\u00ebmi komand\u00eb e shkruar n\u00eb dokumente, make python, instalon paket\u00ebn globalisht n\u00eb sistem (e habitshme, apo jo?).<\/p>\n

\"Instalimi

\nNd\u00ebrtimi me SCIP me parametra nga dokumentacioni kalon me sukses, por or-tools ende refuzon t\u00eb funksionoj\u00eb n\u00eb momentin e importimit.<\/p>\n

\"Instalimi

Megjithat\u00eb, lideri i ekipit t\u00eb or-tools nuk e k\u00ebshilloi p\u00ebrdorimin e GLPK, duke th\u00ebn\u00eb se rezultatet jan\u00eb jo t\u00eb mira, dhe gjithashtu d\u00ebshiroj t\u00eb fitoj mbi SCIP dhe ta b\u00ebj at\u00eb t\u00eb funksionoj\u00eb. Nj\u00eb informacion n\u00eb nj\u00eb postim<\/a><\/noindex> blog m\u00eb shtyu t\u00eb mendoj se paketa e Google funksionon me versione specifike.
