ImportError: Tsis muaj tus qauv npe _build_utils.apple_accelerate

Tom qab ntawd koj yuav xav tau tus tshiab version ntawm numpy. Yog li mus tom ntej thiab hloov kho tus lej kom daws tau qhov teeb meem:

sudo pip -hloov kho numpy

Tom qab ua qhov ntawd, koj kuj yuav tsum ua kom rov ua tiav ntawm cov nab hab sej modules thiab lwm pob, raws li tau piav qhia hauv Kauj Ruam 9.

Kauj Ruam 17: Cov txiaj ntsig

Nov yog qee qhov duab hnub qub uas peb tau txais los ntawm kev ntes lub meteors thiab khiav cov software teeb tsa yav dhau los.
