Izinto ezisisiseko zokusetyenzwa koMsebenzi weWebhu

By Technical specialist

UmSebenzi weWebhu ngumxholo wophumezo weJavaScript owahlukileyo onokwenza izibalo ezibizayo ngaphandle kokwenza umsonto oyintloko womhleli wenze wonke umsebenzi. Ukusetyenzwa komfanekiso wesikhangeli, oko kuthetha ukuseta imodeli kunye nentekelelo inokubaleka kumsonto onoxanduva lwamaqhosha, imiyalezo yenkqubela phambili, igalelo lebrashi, kunye nohlaziyo lwesikrini.

Isiphumo asiko “ukuqhubekeka kwangasemva kwasimahla.” Kwaesi sixhobo sinye sisaqhuba ubalo kwaye sisebenzisa imemori. Inzuzo yezakhiwo kukwahlula: imodeli enzima yokusebenza ayinakwenzeka ukuvala yonke impendulo yojongano ngelixa iqhuba.

Umsonto oyintloko unomsebenzi wojongano lomsebenzisi

Iphepha lomkhangeli liqhele ukwenza iJavaScript kumsonto ongundoqo. Lo msonto ukwalungelelanisa uyilo, ukupeyinta, kunye negalelo. Ukuba isibalo eside sihlala kuyo, ucofa unokuziva ulibazisekile, upopayi unokuyeka, kwaye isikhangeli sinokulumkisa ukuba iphepha aliphenduli.

Umhleli wemifanekiso unomthwalo omkhulu wemfanelo yomxholo ngaphambi kokuba inkcazo iqale:

-fumana ukhetho lwefayile, coma okanye ulahle;

• decode kwaye ubonise umfanekiso;
• ukuhlaziya inkqubela kunye neempazamo; -zoba i-canvas yokujonga kwangaphambili;
• phatha Yongeza kwaye Cima intshukumo yebrashi; -lungiselela ukhuphelo okanye iintshukumo zebhodi eqhotyoshwayo.

Ukubeka imodeli yokwahlula umsebenzi wamanani kumsonto omnye kuya kwenza ukuba loo misebenzi ikhuphisane ngokuthe ngqo. Umsebenzi udala umda ocacileyo.

Umda osekwe kumyalezo

Umhleli kunye nomsebenzi ababelana ngezinto eziqhelekileyo. Banxibelelana ngokuthumela imiyalezo. Ukuqukuqela okwenziwe lula kukhangeleka ngolu hlobo:

1. Umhleli udala okanye asebenzise kwakhona umsebenzi.
2. Icela umsebenzi ukuba aqalise i-inference runtime kunye nemodeli.
3. Ilungiselela idatha yomfanekiso kwaye ithumele isicelo sokucinga.
4. Umsebenzi uguqula idatha ibe yigalelo elilindelekileyo lomfuziselo.
5. Umsebenzi uqhuba imodeli kwaye avelise ixabiso lemaski.
6. Ithumela imaski okanye idatha yeziphumo emva.
7. Umhleli udibanisa i-preview kwaye enze ukulungiswa okanye ukuthumela ngaphandle.

Imiyalezo kufuneka ibandakanye umxholo owaneleyo ukuze itshatise impendulo kwisicelo esichanekileyo. Oku kubalulekile ukuba umsebenzisi ukhetha omnye umfanekiso phambi kokuba umsebenzi wangaphambili ugqitywe. Ujongano kufuneka luphephe ukubonisa isiphumo esidala ngaphezulu komthombo omtsha.

Ukukopa kunye nokudlulisa idatha yomfanekiso

Ukuthumela umyalezo omncinci kutshiphu. Ukuthumela izigidi zamaxabiso e-pixel kunokubiza ukuba isikhangeli kufuneka sikope yonke ibuffer. I-Web APIs inokudlulisa ubunini bebuffers ezithile zokubini endaweni yoko. Isithinteli esigqithiselweyo siyafumaneka kumamkeli ngaphandle kokugcina ikopi esebenzisekayo kwicala lomthumeli.

Olo lungiselelo luza nomqobo woyilo: emva kokudluliselwa, umthumeli akanakuqhubeka esebenzisa ibuffer efanayo ngokungathi iseyeyakhe idatha. Umhleli unokugcina umboniso owahlukileyo wokumelwa, enze isithinteli esizinikeleyo sengqikelelo, okanye akhe kwakhona into ayidingayo kamva.

Ayilulo lonke uphunyezo olusebenzisa udluliselo kwindawo efanayo. Isifundo esiqhelekileyo kukuba ukwahlukana komsonto akwenzi ukunyakaza kwedatha kunyamalale. Ubungakanani bomfanekiso, ubungakanani bebuffer, kunye nenani loguqulelo lisachaphazela ixesha elide kunye nenkumbulo.

Yintoni Easy Background Remover ebeka kuyo umsebenzi

Easy Background Remover isebenzisa uMsebenzi weWebhu one-inference inference runtime yokwahlulahlula isixhobo. Inyathelo elinzima lokusika elizenzekelayo livelisa imaski. Umhleli ke ubonisa isiphumo esidityanisiweyo kwaye uxhasa i-CPU-canvas ibrashi yokucoca.

Olu lwahlulo lunika ukusilela umda oluncedo ngakumbi. Ukuba umsebenzi akakwazi ukuqalisa okanye ukuntlitheka ngexesha lokutsho, ujongano lunokuxela impazamo enxulumene nomsebenzi endaweni yokuxhomekeka kwithebhu enomkhenkce ngokusisigxina njengophawu kuphela.

Ikwaligcina liqondakala ibango lokulungiswa kwendawo. Ukuthumela ipixels ukusuka kwiphepha elongezelelweyo ukuya kubasebenzi balo lunxibelelwano ngaphakathi kwendawo yesikhangeli, hayi ukulayisha kwi-API yokusika ekude. Iseshoni yokuqala inokukhuphela ngokwahlukeneyo imodeli ye-asethi enokusetyenziswa kwakhona; bona Kutheni khuphela imodeli kuqala.

Umsebenzi akenzi ubalo ngoko nangoko

Abasebenzi baphucula ukusabela, hayi isakhono sesixhobo ekrwada. Imodeli isasebenzisa i-CPU, i-GPU, okanye ezinye izixhobo zexesha lokubaleka ngokwendlela isikhangeli inokubonelela ngayo. Igalelo elikhulu lisenokuthatha ixesha elide kwaye lifuna inkumbulo eninzi kunencinane.

Kushiyeke imida emininzi:

• ukuqaliswa kwemodeli kuneendleko zangempela; -i-pixel buffers zihlala kwimemori kumacala omabini ukuba zikhutshiwe;
• uhlengahlengiso kunye nokuguqulwa kwefomathi kuthatha ixesha;
• izixhobo zememori ephantsi zinokuba nzima ngemifanekiso emikhulu;
• abasebenzi abaninzi banokwandisa ingxabano endaweni yokunciphisa;
• ukuthumela ngaphandle kunye nohlaziyo lwe-canvas lusenokubandakanya umsonto ophambili.

Ukuqala abasebenzi abahlanu bengqondo kwimifanekiso emihlanu ayizenzekeli ngokuphindwe kahlanu ngokukhawuleza. Abasebenzi babelana ngomatshini omnye. Imisebenzi efanayo inokukhuphisana kwi-bandwidth yememori kunye nezixhobo zokusebenza, ngelixa imodeli nganye inokuthwala iindleko zayo zememori.

Ingxelo yenkqubela phambili yintsebenziswano

Umsebenzi unokuthumela imiyalezo yesimo, kodwa akazi ngokuzenzekelayo ukuba yeyiphi ipesenti yenkqubela eya kuziva ichanekile. Ukukhuphela imodeli, ukuqaliswa kwexesha lokuqhutywa, ukulungiselela igalelo, intelekelelo, uguqulelo lwemaski, kunye nonikezelo lwangaphambili zizigaba ezahlukeneyo ezinexesha elahlukileyo.

Ezinye izigaba zinamabalo e-byte anokulinganiswa. Ukwenziwa kwemodeli enye kunokuveza kuphela “uqalile” kwaye “ugqityiwe.” Ipesenti egudileyo eqhubela phambili ngokulinganayo ke ngoko inokuba yinto entle kunokuba ibe yimilinganiselo echanekileyo.

I-UI yenkqubela phambili eluncedo ibiza isigaba xa kunokwenzeka: ukulungisa imodeli, ukusetyenzwa komfanekiso, okanye umphumo wokwakha. Ikwaphatha ukusilela kunye nokurhoxiswa endaweni yokushiya i-spinner ngaphandle kwengcaciso.

Ukurhoxiswa kungaphezulu kokufihla ispinner

Ukuba umsebenzisi uvala umfanekiso okanye aqale phantsi, ujongano lunokungahoyi impendulo evela kwisicelo esiphelelwe lixesha. Ukumisa ubalo olusisiseko ngokukhawuleza kunokufuna inkxaso eyongezelelweyo ukusuka kwixesha lokuqhuba okanye ukuphelisa kunye nokubuyisela umsebenzi.

Ukuphelisa umsebenzi kuyisigqibo, kodwa siyayilahla imeko yakhe yokuqala. Umsebenzi olandelayo unokufuna ukulayisha kwaye uqalise imodeli kwakhona. Kumsebenzi omfutshane, ukuphawula isiphumo sidala kunokubiza imali encinane kunokudiliza yonke into.

Ukhetho oluchanekileyo luxhomekeke kuxinzelelo lwememori, ubude bokusebenza, kunye nobuchule bexesha lokubaleka. Ngokwembono yomsebenzisi, umgaqo obalulekileyo ngowokuba umsebenzi omdala akufuneki ubhale ngaphezulu ukuhlelwa kwangoku.

Iimpazamo kufuneka ziwele umda nazo

Umkhethe ngaphakathi komsebenzi awubi yinto eqhelekileyo kumsonto oyintloko. Umsebenzi kufuneka axele iimpazamo ezinokusebenziseka, kwaye umhleli kufuneka aphulaphule ukusilela kwinqanaba labasebenzi.

Ukuphatha impazamo elungileyo kwahlula ubuncinci:

• imodeli ye-asethi ayifumaneki;
• ukuqaliswa kwemodeli kusilele; -i-decode decode okanye ukulungiswa kwegalelo kusilele;
• uthelekiso aluphumelelanga;
• umsebenzi wayeka ngokungalindelekanga;
• isiphumo asisesesosicelo sangoku.

Oku kuyenzeka ngakumbi kune-generic “ikhona into engahambanga kakuhle,” ngakumbi xa useto lolwelo lokuqala kunye nokulungiswa komfanekiso okuqhelekileyo kunoncedo olwahlukileyo.

Imveliso yabasebenzi iseyimaski yokuqala kuphela

Uyilo lwemisonto aluphuculi umphetho ongacacanga ngokwawo. Umsebenzi unokubuyisela isigqubuthelo sobuso esisebenzayo esisaphosa uboya, imathiriyeli ebonakalayo, imitya emxinwa, okanye isithunzi esifunekayo. Leyo yimibuzo yokwahlulahlula kunye nenjongo.

Umsebenzi womhleli uqalisa kwakhona emva kwentekelelo: yenza isigqubuthelo semaski kwisixokelelwano esisebenzayo, dibanisa umboniso wangaphambili, vumela umsebenzisi awucokise, kwaye athumele ngaphandle imeko yangoku. Isisombululo semaski vs ubungakanani bemboniso ichaza ukuba kutheni ezonkqubo zolungelelaniso zingabhideki.

Imodeli yengqondo emfutshane

Cinga ngomsebenzi njengengcali yendawo emva kwefestile yomyalezo:

• umhleli ungumnini wonxibelelwano;
• Umsebenzi ungumnikazi womsebenzi onzima wokuthelekelela;
• idatha yomfanekiso webinary iwela umda ochaziweyo;
• Umsebenzi ubuyisela isigqubuthelo, kungekhona isigwebo esigqityiweyo malunga macala onke;
• umhleli uhlala enoxanduva lobume bangoku, uphononongo, ukulungiswa, kunye nokuthumela ngaphandle.

Kumbono wemodeli yeepixels ngokwazo, qhubeka ngo Yintoni ebonwa yimodeli yokusika kwisixhobo. Ukuze ufumane isishwankathelo esisebenzayo, bona Indlela ukususwa kwemvelaphi yasekuhlaleni kusebenza.
