I-Pytorch

Enkathini yobuhlakani bokwenziwa nokufunda okujulile, i-PyTorch iwumthombo ovulekile wolwazi wokufunda womshini ovulekile wePython onokuhlanganisa kwe-tensor kanye namanethiwekhi ajulile e-neural. Esinye sezici zayo eziningi eziwusizo yi-PyTorchVideo, okuyithuluzi eliklanyelwe ngokukhethekile imisebenzi yokuqonda ividiyo. Kulesi sihloko, sizongena emhlabeni we-PyTorchVideo, izinkinga engasisiza ukuthi sibhekane nazo, futhi sikuhambise ekusetshenzisweni kwayo.

Emhlabeni wokufunda komshini nobuhlakani bokwenziwa, kuvamile ukusebenza **namamodeli aqeqeshwe kusengaphambili** ukuze kuzuzwe imiphumela esheshayo nenembe kakhulu. Lawa mamodeli asevele aqeqeshiwe kumasethi edatha amakhulu futhi aselungele ukusetshenziswa. Ukulayisha imodeli eqeqeshwe kusengaphambili kungonga isikhathi esiningi nezisetshenziswa uma kuqhathaniswa nokuqala ekuqaleni. Kulesi sihloko, sizohlola ukuthi singalayisha kanjani imodeli eqeqeshwe kusengaphambili kusetshenziswa iPython, sigxile kakhulu kumtapo wolwazi osetshenziswa kabanzi obizwa ngeTensorFlow. Sizohlinzeka ngesixazululo senkinga, sixoxe ngemitapo yolwazi edingekayo kanye nemisebenzi, futhi sihambe ngencazelo yesinyathelo nesinyathelo sekhodi.

Eminyakeni yakamuva, kube nentshisekelo ekhulayo ekucutshungulweni kolimi lwemvelo (NLP) nokufunda komshini, ngenxa yokuthuthukiswa kwamamodeli anamandla afana nama-Hugging Face's Transformers. Lawa mamodeli aguqule indlela esihlaziya ngayo futhi sicubungula umbhalo, anikeze ukuqonda okungcono nokuqonda. Ukushuna kahle lawa mamodeli sekuphenduke isihloko esidumile, njengoba kuvumela abathuthukisi ukuthi benze ngendlela oyifisayo amamodeli aqeqeshwe ngaphambilini emisebenzini yawo ethile futhi bazuze ukusebenza okuphezulu. Kulesi sihloko, sizoxoxa ngendlela yokushuna kahle imodeli ye-Hugging Face Transformer, sidlule encazelweni yesinyathelo ngesinyathelo sekhodi, futhi sijule kwezinye izihloko ezihlobene, imisebenzi, kanye nemitapo yolwazi ehilelekile kule nqubo.

Izitayela zemfashini ziyafika zidlule, kodwa izisekelo eziyisisekelo zezitayela, ukubukeka, nezinhlanganisela ngokuvamile zingalandelelwa emlandweni wemfashini. Kulesi sihloko, sizohlola izitayela ezihlukahlukene, kusukela kokwakudala kuye kokuhlolwa, futhi sinikeze imininingwane ngemibala nezingubo ezibonisa kahle ngayinye ngayinye. Sizophinde sithinte umlando wesitayela ngasinye, singene ngemvelaphi yaso kanye nokuziphendukela kwemvelo ngokuhamba kwesikhathi. Kungakhathaliseki ukuthi ungumakadebona wemfashini noma usanda kuqala ukungena emkhakheni wemfashini, kukhona ongakufunda kuwo wonke umuntu.

Umhlaba wokuhlaziywa kwedatha ngokuvamile udinga ukusebenza ngedatha yochungechunge lwesikhathi, futhi indlela evamile esetshenziswa ekuphatheni idatha enjalo isebenzisa umqondo we iwindi eligoqayo. Iwindi eligoqayo, ngezinye izikhathi elibizwa ngokuthi iwindi elinyakazayo noma iwindi elislayidayo, liyindlela esivumela ukuthi sihlukanise idathasethi yethu ibe yizingxenyana ezincane, siwacubungule, futhi sithole imininingwane ewusizo ochungechungeni oluncane oluwumphumela. Le ndlela enamandla isetshenziswa kakhulu kwezezimali, ukubikezela, nokuhlaziywa kwethrendi, ikwenze kube ikhono elibalulekile ukuba nalo ebhokisini lakho lamathuluzi lokuhlaziya. Kulesi sihloko, sizohlola umqondo wefasitela eligoqayo, sibhekane nenkinga, sihlukanise isixazululo saso sibe izinyathelo eziqondakala kalula, futhi sixoxe ngemitapo yolwazi yePython ehlobene nemisebenzi engenza ukuphila kwethu kube lula.

Emhlabeni wanamuhla wokuthuthukiswa kwesofthiwe, ukuphatha ukuncika nokuqinisekisa ukusebenza kahle kwezinhlelo zokusebenza kuzo zonke izinkundla ezihlukene sekubalulekile. Olunye lwezilimi zokuhlela ezisetshenziswa kakhulu, i-Python, ihlinzeka ngendawo yemvelo ephelele yemitapo yolwazi kanye nokuncika ukuze kuhlangatshezwane nezidingo eziningi zohlelo lokusebenza. I-Anaconda, ukusatshalaliswa kwePython okudumile, yenza le nqubo ibe lula ngokunikeza indawo esebenziseka kalula yokuphatha ukuncika nokusebenza ezinhlelweni zeWindows. Kulesi sihloko, sizodalula ubunkimbinkimbi bokuphatha ukuncika sisebenzisa i-Anaconda futhi sibonise izindlela ezifanele zokubhekana nalolu daba. Endleleni, sizohlola imitapo yolwazi ehlukahlukene yePython nemisebenzi engasiza kule nqubo.

Imfashini ibilokhu iyimboni eguquguqukayo nethuthuka njalo, lapho kuvela khona izitayela ezintsha nezindala zibuyekezwa futhi zicatshangelwe kabusha. Kusukela ebuhleni besikhathi esidlule kuya ezinkambisweni zokuhlola zanamuhla, imfashini iwuhlobo olubalulekile lokuziveza kanye nophawu lomuntu ngamunye. Ukuze sihlole lesi sihloko esithakazelisayo, sizongena emlandweni wezitayela zemfashini ezihlukahlukene, sihlaziye izingubo nemibala eyichazayo, futhi sithole ugqozi ekubukekeni komzila wezindiza owubukhazikhazi kakhulu. Endleleni, sizobona nokuthi iPython ingasisiza kanjani siqonde kangcono ubunkimbinkimbi bemfashini. Ngakho-ke, ake siqale kulokhu kuhlola imfashini nobuchwepheshe.

Izwe lemfashini lihlala lishintsha, nezitayela ezintsha, ukubukeka, kanye nezitayela ezivela njalo. Kungakhathaliseki ukuthi ungumklami ofuna ugqozi noma umshisekeli wemfashini, ukuqonda lezi zitayela ezihlukahlukene kubalulekile ukuze uhlale unolwazi ngentuthuko yakamuva. Kulo mhlahlandlela obanzi, sihlose ukumboza ubunkimbinkimbi bezitayela ezahlukene, ukubukeka, nokuthambekela kwemfashini, kanye nomlando wesitayela ngasinye nendlela yokugqoka. Ngaphezu kwalokho, sizohlola indima yokuhlela, ikakhulukazi iPython, emhlabeni wemfashini ne-SEO.

Isingeniso

Emhlabeni othuthukayo ngokushesha wokufunda okujulile namanethiwekhi emizwa, imitapo yolwazi nezinhlaka kubalulekile ekwenzeni lula kanye nokusheshisa inqubo yokuthuthukiswa. I-PyTorch Lightning iwumtapo wezincwadi onamandla owakhiwe phezu kwePyTorch ethandwa kakhulu. Umbani uklanyelwe ukuvumela Ososayensi Bedatha Nonjiniyela be-ML ukuthi bakale kalula amamodeli abo, bagweme ikhodi ye-boilerplate, futhi bathuthukise ukufundeka sekukonke. Nokho, ngenkathi usebenza ne-PyTorch Lightning, ungase uzithole ubhekene nezinkinga ezifana nephutha lesichasiso se-'pytorch_lightning.metrics'. Kulesi sihloko, sizobhekana nenkinga futhi sikuhambise ngesixazululo sayo, sephule ikhodi ukuze siqonde kangcono. Ngaphezu kwalokho, sizoxoxa ngemitapo yolwazi ehlobene nemisebenzi ehilelekile ekuxazululeni lolu daba.
