NumPy Scientific Computing Python Library 1.19 Yatulutsidwa

Ipezeka kutulutsidwa kwa laibulale ya Python yamakompyuta asayansi NumPy 1.19, yokhazikika pakugwira ntchito ndi ma multidimensional arrays ndi matrices, komanso kupereka mndandanda waukulu wa ntchito ndi kukhazikitsidwa kwa ma algorithms osiyanasiyana okhudzana ndi kugwiritsa ntchito matrices. NumPy ndi amodzi mwa malaibulale odziwika kwambiri omwe amagwiritsidwa ntchito powerengera zasayansi. Khodi ya polojekitiyi imalembedwa ku Python pogwiritsa ntchito kukhathamiritsa mu C ndi wogawidwa ndi pansi pa layisensi ya BSD.

NumPy 1.19 sichigwirizananso ndi Python 3.5 ndikuchotsa kachidindo kuti ithandizire Python 2 (wosanjikiza wa numpy.compat wasiyidwa m'malo pano). Mitundu yothandizidwa ndi Python 3.6, 3.7 ndi 3.8. Kukula kwa module kunapitilira numpy.mwachisawawa kuti mugwiritse ntchito ndi zitsanzo zachisawawa. Kuthandizira kwabwino kwa ma wheel NumPy pamapangidwe a Aarch64 komanso mukamagwiritsa ntchito Python. pypy. Zokulitsidwa functionality numpy.frompyfunc, np.str_, kodi.copy, kodi.linalg.multi_dot, kodi.count_nonzero ndi numpy.array_equal. Kuzindikirika bwino kwa kuthekera kwa CPU monga chithandizo cha AVX. Kukhazikitsa kowonjezera komwe kumagwira ntchito nthawi 5-7 mwachangu np.exp kutengera AVX512, yogwiritsidwa ntchito polowetsa deta yamtundu wa np.float64.
