Hapat e par\u00eb<\/h2>\n

\nT\u00eb tre paketat ekzistojn\u00eb n\u00eb repozitorin e Python-it, k\u00ebshtu q\u00eb i instalojm\u00eb p\u00ebrmes pip.<\/p>\n

\u00c7do nj\u00ebri prej tyre ka nd\u00ebrfaqen e tij, dhe or-tools u zgjodh sakt\u00ebsisht p\u00ebr t\u00eb provuar disa paketa pa e shkruar programin n\u00eb m\u00ebnyr\u00eb t\u00eb konsiderueshme, k\u00ebshtu q\u00eb detyra \u00ebsht\u00eb q\u00eb or-tools t\u00eb lidhet me k\u00ebta zgjidh\u00ebs dhe t'i jap\u00eb mund\u00ebsin\u00eb q\u00eb t\u00eb ekzekutohen p\u00ebrmes tij. Dhe \u00e7far\u00eb mendoni? or-tools i instaluar p\u00ebrmes pip nuk i sheh zgjidh\u00ebsit e instaluar p\u00ebrmes pip, dhe ata nuk e shohin at\u00eb (kush do t\u00eb mendonte). Prandaj, duhet t\u00eb shohim se \u00e7far\u00eb shkruhet n\u00eb dokumentacion<\/a><\/noindex>.
\nDokumentet thon\u00eb se duhet t\u00eb nd\u00ebrtohet nga burimi q\u00eb or-tools t\u00eb lidhet me paketat e jashtme. Provojm\u00eb t\u00eb nd\u00ebrtojm\u00eb, dhe nuk dalin gj\u00ebra sepse zgjidh\u00ebsit e instaluar p\u00ebrmes pip nuk jan\u00eb t\u00eb duksh\u00ebm.
\nP\u00ebrkat\u00ebsisht, m\u00ebnyrat m\u00eb t\u00eb thjeshta p\u00ebr t\u00eb instaluar t\u00eb gjitha paketat p\u00ebrmes pip nuk funksionojn\u00eb, sepse or-tools nuk merr zgjidh\u00ebsit, zgjidh\u00ebsit nuk instalojn\u00eb bibliotekat ashtu si\u00e7 k\u00ebrkon or-tools, t\u00eb gjith\u00eb hedhin gabime, t\u00eb quajn\u00eb injorant dhe e tallin. <\/p>\n

M\u00eb pas n\u00eb dokumenti<\/a><\/noindex> thot\u00eb se duhet nd\u00ebrtuar zgjidh\u00ebsit nga burimi dhe pastaj nd\u00ebrtuar or-tools nga burimi. E th\u00ebn\u00eb e b\u00ebr\u00eb! Instalova SCIP, instalova GLPK, por doli nj\u00eb pyetje e pa p\u00ebrshkruar n\u00eb dokumentacion se si t\u00eb vendos or-tools n\u00eb nj\u00eb mjedis virtual. <\/p>\n

E vetmja e shkruar n\u00eb dokumente, komanda make python instalon paket\u00ebn globalisht n\u00eb sistem (e \u00e7uditshme, apo jo?).<\/p>\n

Megjithat\u00eb, pata fat: gjat\u00eb k\u00ebrkimeve inxhinierike me metod\u00ebn e majmun\u00ebve t\u00eb pafund, rast\u00ebsisht nisa komand\u00ebn make help, dhe m\u00eb u shfaq nj\u00eb list\u00eb e t\u00eb gjitha opsioneve t\u00eb nd\u00ebrtimit t\u00eb or-tools, p\u00ebrfshir\u00eb nj\u00eb mund\u00ebsi p\u00ebr t\u00eb nd\u00ebrtuar paket\u00ebn wheel. Kjo \u00ebsht\u00eb komanda make python_package, n\u00ebse nuk e dinit (do ta p\u00ebrs\u00ebris s\u00ebrish n\u00eb fund). Pra, k\u00ebshtu q\u00eb, ka ardhur koha p\u00ebr t\u00eb nd\u00ebrtuar dhe ekzekutuar?<\/p>\n

\"Instalimi
\n<\/p>\n

Po k\u00ebrkojm\u00eb problemin<\/h2>\n

\nNuk funksionon asgj\u00eb n\u00eb faz\u00ebn e nd\u00ebrtimit t\u00eb or-tools, ai ankohet p\u00ebr biblioteka t\u00eb k\u00ebqija GLPK.<\/p>\n

\"Instalimi
\n
\nNd\u00ebrtimi me SCIP sipas parametreve nga dokumentacioni kalon me sukses, por or-tools ende refuzon t\u00eb punoj\u00eb n\u00eb momentin e importimit.<\/p>\n

\"Instalimi
\n
\nNuk gjeti ndonj\u00eb zgjidhje p\u00ebr k\u00ebto probleme vet\u00eb, prandaj shkova n\u00eb GitHub te zhvilluesit p\u00ebr t\u00eb pyetur pse instalimi sipas udh\u00ebzimeve t\u00eb tyre jep gabime diku brenda kodit t\u00eb tyre.<\/p>\n

\"Instalimi
\nHmm, faleminderit p\u00ebr shpjegimet
\n<\/i>
\nNd\u00ebrsa prisja p\u00ebrgjigje n\u00eb GitHub, po k\u00ebrkoja n\u00eb Internet, shpresoj p\u00ebr t\u00eb gjetur di\u00e7ka q\u00eb mund t\u00eb m\u00eb ndihmoj\u00eb. Dhe si\u00e7 nuk \u00ebsht\u00eb e \u00e7uditshme, e gjeta. Kjo ishte blog<\/a><\/noindex> nga lideri i projektit, ku ai shkruante se si t\u00eb lidhej GLPK me or-tools. Dhe ky m\u00ebnyr\u00eb p\u00ebrfundimisht funksionoi! Tani, n\u00ebse nd\u00ebrtojm\u00eb gjith\u00e7ka pa SCIP, por me GLPK, at\u00ebher\u00eb me k\u00ebt\u00eb madje mund t\u00eb punojm\u00eb. Nj\u00eb p\u00ebrparim tashm\u00eb.<\/p>\n

Megjithat\u00eb, lideri i ekipit or-tools nuk e rekomandoi p\u00ebrdorimin e GLPK, duke th\u00ebn\u00eb se rezultatet nuk ishin t\u00eb shk\u00eblqyera, dhe gjithashtu d\u00ebshirojm\u00eb t\u00eb mposhtim SCIP dhe ta b\u00ebjm\u00eb t\u00eb funksionoj\u00eb. Nj\u00eb fqinj post<\/a><\/noindex> n\u00eb blog m\u00eb nxori n\u00eb mendje se paketa e Google funksionon me versione t\u00eb caktuara. Shikojm\u00eb list\u00ebn e ndryshimeve t\u00eb l\u00ebshimeve<\/a><\/noindex> dhe shohim nj\u00eb tregues t\u00eb qart\u00eb t\u00eb versionit 6.0.0. Edhe pse n\u00eb makefile \u00ebsht\u00eb e sh\u00ebnuar versioni 6.0.2, provoni t\u00eb instaloni nj\u00eb version m\u00eb t\u00eb vjet\u00ebr dhe voil\u00e0!<\/p>\n

Dhe tani nj\u00eb her\u00eb tjet\u00ebr nj\u00eb sekuenc\u00eb e pun\u00ebs.
