Rozhodol som sa z\u00fa\u010dastni\u0165 sa s\u00fa\u0165a\u017ee<\/a><\/noindex> a potreboval som na to pou\u017ei\u0165 bal\u00edky na rie\u0161enie optimaliza\u010dn\u00fdch \u00faloh. Vybral som si n\u00e1stroj or-tools od Googlu, ktor\u00fd predstavuje rozhranie pre r\u00f4znych rie\u0161ite\u013eov.

Av\u0161ak sme chudobn\u00ed a pou\u017eijeme bezplatn\u00e9 SCIP a GLPK (od tuzemsk\u00e9ho v\u00fdvoj\u00e1ra, mimochodom). Na moje prekvapenie som nena\u0161iel \u017eiadne in\u0161trukcie o tom, ako rozbehn\u00fa\u0165 toto v\u0161etko v virtu\u00e1lnom prostred\u00ed Pythonu, ani v na\u0161ich, ani v anglicky hovoriacich segmentoch internetu, a tak som musel trocha z\u00e1pasi\u0165. Pre t\u00fdch, ktor\u00ed ve\u013emi posp\u00edchaj\u00fa, \u010d\u00edtajte hne\u010f tu<\/a><\/noindex>, ostatn\u00fdm pon\u00fakam spozna\u0165 moju grafom\u00e1niu, popisuj\u00facu peripetie in\u0161tal\u00e1cie googlovsk\u00e9ho softv\u00e9ru. \u00c1no, zabudol som poveda\u0165, \u017ee v\u0161etko sa in\u0161talovalo na Manjaro Linuxe.<\/p>\n

\"In\u0161tal\u00e1cia<\/a><\/noindex><\/p>\n

Prv\u00e9 kroky<\/h2>\n

\nV\u0161etky tri bal\u00edky existuj\u00fa v repozit\u00e1ri Pythonu, tak\u017ee ich in\u0161talujeme pomocou pip.<\/p>\n

Ka\u017ed\u00fd z nich m\u00e1 svoje rozhranie, a or-tools bol vybran\u00fd pr\u00e1ve na to, aby som mohol sk\u00fa\u0161a\u0165 r\u00f4zne bal\u00edky, bez podstatn\u00e9ho prepisovania programu, tak\u017ee \u00falohou je, aby or-tools prepojil tieto rie\u0161itele a umo\u017enil ich sp\u00fa\u0161\u0165anie cez seba. A \u010do si mysl\u00edte? Nain\u0161talovan\u00fd or-tools cez pip nevid\u00ed in\u0161talovan\u00e9 rie\u0161itele cez pip a oni nevidia jeho (kto by to mohol poveda\u0165). Znamen\u00e1 to, \u017ee sa mus\u00edme pozrie\u0165, \u010do p\u00ed\u0161u v dokumen\u00e1cie<\/a><\/noindex>.
\nDokument\u00e1cii p\u00ed\u0161u, \u017ee je potrebn\u00e9 zostavi\u0165 z prame\u0148ov, aby or-tools prepojil extern\u00e9 bal\u00edky. Sk\u00fa\u0161ame zostavi\u0165, a ni\u010d sa nedar\u00ed, preto\u017ee in\u0161talovan\u00e9 rie\u0161itele cez pip nie s\u00fa vidite\u013en\u00e9.
\nTeda najjednoduch\u0161ie sp\u00f4soby in\u0161tal\u00e1cie v\u0161etk\u00fdch bal\u00edkov cez pip nefunguj\u00fa, preto\u017ee or-tools neprep\u00e1ja rie\u0161itele, rie\u0161itelia nenain\u0161taluj\u00fa kni\u017enice tak, ako si or-tools \u017eel\u00e1, v\u0161etci h\u00e1d\u017eu chyby a naz\u00fdvaj\u00fa \u0165a hlup\u00e1kom a posmievaj\u00fa sa ti. <\/p>\n

\u010ealej v dokument\u00e1cii<\/a><\/noindex> p\u00ed\u0161u, \u017ee je potrebn\u00e9 zostavi\u0165 rie\u0161itele z prame\u0148ov, potom z prame\u0148ov zostavi\u0165 samotn\u00fd or-tools. Povedan\u00e9-skonan\u00e9! Nain\u0161taloval som SCIP, nain\u0161taloval som GLPK, ale objavil sa nepop\u00edsan\u00fd v dokument\u00e1cii probl\u00e9m, ako nain\u0161talova\u0165 or-tools do virtu\u00e1lneho prostredia. <\/p>\n

Jedin\u00fd pr\u00edkaz zap\u00edsan\u00fd v dokumentoch make python nain\u0161taluje bal\u00edk glob\u00e1lne do syst\u00e9mu (prekvapuj\u00face, v\u0161ak?).<\/p>\n

Mne sa v\u0161ak podarilo: po\u010das in\u017einierskeho h\u013eadania met\u00f3dou nekone\u010dn\u00fdch op\u00edc som n\u00e1hodou zadal pr\u00edkaz make help a dostal som zoznam v\u0161etk\u00fdch mo\u017en\u00fdch zostaven\u00ed or-tools, medzi ktor\u00fdmi bola aj mo\u017enos\u0165 zostavi\u0165 wheel bal\u00edk. Je to pr\u00edkaz make python_package, ak by to niekoho zauj\u00edmalo (m\u00e1m ho na mysli e\u0161te raz na konci). Tak\u017ee, je \u010das zostavi\u0165 a spusti\u0165?<\/p>\n

\"In\u0161tal\u00e1cia

H\u013ead\u00e1me probl\u00e9m<\/h2>\n

\nNi\u010d nefunguje v etape zostavovania or-tools, s\u0165a\u017euje si na zl\u00e9 kni\u017enice GLPK.<\/p>\n

\"In\u0161tal\u00e1cia
\n
\nZostavenie so SCIP s parametrami z dokument\u00e1cie prebieha \u00faspe\u0161ne, ale or-tools sa aj tak odmieta spusti\u0165 pri importovan\u00ed.<\/p>\n

\"In\u0161tal\u00e1cia
\n
\nSamostatne som nena\u0161iel rie\u0161enie t\u00fdchto probl\u00e9mov, tak som sa vybral na GitHub za v\u00fdvoj\u00e1rmi, aby som sa op\u00fdtal, pre\u010do in\u0161tal\u00e1cia pod\u013ea ich pokynov vyvol\u00e1va chyby niekde vo vn\u00fatri ich k\u00f3du.<\/p>\n

\"In\u0161tal\u00e1cia
\nHmmm, \u010fakujem za vysvetlenia
\n<\/i>
\nK\u00fdm som \u010dakal na odpove\u010f na GitHube, preh\u013ead\u00e1val som internet, v n\u00e1deji, \u017ee n\u00e1jdem nie\u010do, \u010do mi pom\u00f4\u017ee. A ako to nie je prekvapuj\u00face, na\u0161iel som to. Bol to blog<\/a><\/noindex> teamlead projektu, kde p\u00edsal o tom, ako prepoji\u0165 GLPK s or-tools. A tento sp\u00f4sob kone\u010dne zafungoval! Teraz, ak sa v\u0161etko zostav\u00ed bez SCIP, ale s GLPK, d\u00e1 sa s t\u00fdm aj pracova\u0165. U\u017e pokrok.<\/p>\n

Av\u0161ak teamlead t\u00edmu or-tools neodpor\u00fa\u010dal pou\u017e\u00edva\u0165 GLPK, hovoril, \u017ee v\u00fdsledky s\u00fa priam zl\u00e9 a je potrebn\u00e9 porazi\u0165 SCIP a don\u00fati\u0165 ho, aby fungoval. Susedn\u00fd pr\u00edspevok<\/a><\/noindex> blog ma naviedol na my\u0161lienku, \u017ee googlovsk\u00fd bal\u00edk funguje s konkr\u00e9tnymi verziami. Pozrieme sa na zoznam zmien vydania<\/a><\/noindex> a vid\u00edme tam jasn\u00e9 uvedenie verzie 6.0.0. Napriek tomu, \u017ee v makefile je uveden\u00e1 verzia 6.0.2, sk\u00fa\u0161ame nain\u0161talova\u0165 star\u0161iu verziu a voila!<\/p>\n

A teraz e\u0161te raz pracovn\u00fd postup.

Postup in\u0161tal\u00e1cie<\/h2>\n

<\/p>\n

    \n
  1. Stiahnu\u0165 arch\u00edv SCIP, a uisti\u0165 sa, \u017ee tu<\/a><\/noindex> je jasne uveden\u00e1 podpora verzie, ktor\u00fa s\u0165ahujete (v mojom pr\u00edpade developers.google.com\/optimization\/support\/release_notes#support-for-scip-6.0.0<\/a><\/noindex>) a rozbali\u0165.<\/li>\n
  2. Stiahnu\u0165 GLPK (v \u010dase p\u00edsania posledn\u00e1 verzia 4.65) a rozbali\u0165.<\/li>\n
  3. Nain\u0161talova\u0165 SCIP pr\u00edkazom\n
    make GMP=false READLINE=false TPI=tny ZIMPL=false scipoptlib install INSTALLDIR=\/scipoptsuite-6.0.0\n<\/code><\/pre>\n<\/li>\n
  4. Nain\u0161talova\u0165 GLPK pr\u00edkazom:\n
    .\/configure --prefix= --with-pic --enable-shared\nmake\nmake install\n<\/code><\/pre>\n<\/li>\n
  5. Stiahnu\u0165 OR-Tools z GitHubu\n
    git clone https:\/\/github.com\/google\/or-tools<\/code><\/pre>\n<\/li>\n
  6. Nain\u0161talova\u0165 OR-Tools pr\u00edkazmi:\n
    make third_party\nmake python_package\n<\/code><\/pre>\n
    \nAk posledn\u00fd pr\u00edkaz nefunguje, nain\u0161talujte wheel pr\u00edkazom:<\/p>\n
    pip install wheel<\/code><\/pre>\n<\/li>\n
  7. Aktivujte virtu\u00e1lne prostredie, prejdite do prie\u010dinka s Python bal\u00edkom a nain\u0161talujte ho odtia\u013e.\n
    Ak potrebujete nain\u0161talova\u0165 nie do virtu\u00e1lneho prostredia, ale glob\u00e1lne pre cel\u00fd syst\u00e9m, namiesto:<\/p>\n
    make python_package<\/code><\/pre>\n
    \nvykonajte pr\u00edkaz:<\/p>\n
    make python\n<\/code><\/pre>\n<\/li>\n<\/ol>\n
