PyTorch Uyasebenza

I-PyTorch iwuhlaka oluvulekile lokuthuthukisa ukufunda komshini nokufunda okujulile, olugxile ekuchazeni amamodeli, ekuqeqesheni nasekuphindaphindeni ukuhlola. Isebenzisa kakhulu i-Python, futhi igrafu yokubala yakhiwa ngesikhathi sokusebenza, ngakho onjiniyela bangahlola ngokuqondile imiphumela ephakathi futhi balungise inqubo yokubala.

Umkhiqizo ulungele abacwaningi abadinga ukuqinisekisa ngokuphindaphindiwe izinhlelo zamamodeli, futhi ulungele nonjiniyela abasebenzisa amamodeli okufunda okujulile kumaphrojekthi angempela.

Uhlaka lunikeza ama-tensor anezinhlangothi eziningi namakhono okubala ahlobene, futhi lungasebenzisa i-GPU ekubaleni okuhambisanayo; uhlelo lwe-automatic differentiation lungathola ama-gradient amapharamitha ngokwenqubo yokubala eya phambili, lunciphise umsebenzi wokuthola mathupha ama-gradient okuqeqesha.

Imojuli yamanethiwekhi ezinzwa iqukethe izingxenye ezifana nezendlalelo zenethiwekhi, imisebenzi yokwenza kusebenze nemisebenzi yokulahlekelwa, ezingasetshenziswa ukuhlanganisa ukwakheka kwemodeli. Imitapo yolwazi ehlobene ihlanganisa umbono, umsindo nombhalo, kuyilapho i-TorchScript ne-TorchServe zingasetshenziselwa izinqubo zokuguqula nokuthumela amamodeli.

I-PyTorch ilungele izifundo nokuhlola kokufunda okujulile, ukuthuthukiswa kwama-prototype amamodeli, ukuqinisekiswa kwezinqubo zokuqeqesha, kanye nokuthuthukiswa kwamaphrojekthi ombono wekhompyutha, ukucutshungulwa kolimi lwemvelo, umsindo nezinye izindawo.

Abacwaningi bangasebenzisa igrafu yokubala eyakhiwa ngesikhathi sokusebenza ukuze balungise ngokushesha umqondo wokuhlola; onjiniyela bokufunda komshini bangaqhubeka nokuguqula nokuthumela imodeli ngemva kokuqeqeshwa; ososayensi bedatha bangahlanganisa amamodeli okufunda okujulile ezinqubweni zokucubungula idatha ezisekelwe ku-Python.

Ngaphambi kokusetshenziswa, kudingeka ube nolwazi oluthile lokuhlela nge-Python, ukubala kwama-tensor nezisekelo zamanethiwekhi ezinzwa. Igrafu yokubala eyakhiwa ngesikhathi sokusebenza ilusizo ekulungiseni nasekuhloleni, kodwa amaphrojekthi ayinkimbinkimbi asadinga ukuthi uzihlelele ngokwakho amapayipi edatha, izinsiza zokuqeqesha, izinguqulo zamamodeli nezinqubo zokuthumela.

Imitapo yolwazi yemvelo yombono, umsindo nombhalo inganikeza izingxenye ezengeziwe, kodwa amamodeli athile, amasethi edatha nezindlela zokuthumela kufanele kuqinisekiswe ngokwehlukana kuye ngomsebenzi wephrojekthi. Lapho ikhodi yocwaningo idluliselwa endaweni yokukhiqiza, kudingeka futhi kuhlolwe izinsiza zokubala, izixhumanisi zesevisi nezindleko zokusebenza nokugcinwa.
