NumPy Scientific Computing Python Library 1.17.0 Yatulutsidwa

chinachitika kutulutsidwa kwa laibulale ya Python yamakompyuta asayansi NumPy 1.17, 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 1.17 kumasulidwa chodabwitsa kubweretsa kukhathamiritsa komwe kumapangitsa kuti ntchito zina zitheke, ndikuthetsa chithandizo cha Python 2.7. Kuti mugwire ntchito, muyenera Python 3.5-3.7. Zosintha zina ndi izi:

• Kukhazikitsa gawo la FFT (Fast Fourier Transforms) pochita kusintha mwachangu kwa Fourier kwasunthidwa kuchoka ku fftpack kupita ku yachangu komanso yolondola kwambiri. pocketfft.
• Mulinso gawo latsopano lokulitsa
  mwachisawawa, chomwe chimapereka kusankha kwa majenereta anayi a pseudo-random (MT19937, PCG64, Philox ndi SFC64) ndikugwiritsa ntchito njira yabwino yopangira entropy ikagwiritsidwa ntchito mofananira.

• Wowonjezera bitwise (radix) ndi wosakanizidwa (timsort) masanjidwe omwe amasankhidwa okha kutengera mtundu wa data.
• Mwachikhazikitso, kuthekera kopitilira ntchito za NumPy kumathandizidwa.
