Isticmaalka kayd diyaarsan oo loogu talagalay fetch_20newsgroups ee scikit-learn
Samee kayd fetch_20newsgroups oo ku habboon iyadoo la adeegsanayo fetcher-ka la taageeray, u gudbi, kadibna isticmaal download_if_missing=False.
Marka bartilmaameedku aanu ku soo dejisan karin borokseejkiisa, ku diyaari xogta ururka fetcher-ka la taageeray oo ku yaal waddo shaqo oo la ansixiyay oo u gudbi kaydka ku habboon. Bartilmaameedka:
from sklearn.datasets import fetch_20newsgroups
dataset = fetch_20newsgroups(
data_home='/path/to/prepared-scikit-data',
download_if_missing=False,
)download_if_missing=False wuxuu kiciyaa OSError haddii xogta maqan tahay; ma isku dayo waddo kale oo soo dejineed. Isticmaal natiijadaas si aad u kala saarto diyaarinta maqan iyo hawlgalka xogta dambe.
La jaanqaad goobta kaydka bartilmaameedka. get_data_home wuxuu soo sheegaa qiimaha caadiga ah, halka SCIKIT_LEARN_DATA ama data_home cad uu beddeli karo. Kayd ku yaal guriga isticmaale kale halkan si otomaatig ah looma arko.
Samee kaydka adigoo isticmaalaya nooca maktabadda ee ku habboon iyo fetcher-ka laftiisa. Faylka tar ama pickle gudaha gacanta lagu sameeyay lama beddeli karo natiijadaas la taageeray.
Soo dejinta tooska ah, habeey borokseejka deegaanka soo dejisaha dhabta ah ka hor inta Python uusan bilaaban. Halka martigeliyaha xogta ururku yahay mid dadweyne oo soo dejinta borokseej dadweyne la ogol yahay, liiska borokseej HTTP wuxuu bixiyaa musharraxiin qiimaha deegaanka borokseej HTTP ee soo dejisaha. Rakibista scikit-learn ama isticmaalka tusaalooyinka load_* ee lagu daray ma tababarto soo dejinta xogta ururka ee shabakada.
