numpy amax vs max
] Đã hỏi 5 năm trước. numpy max vs amax vs maximum numpy has three different functions which seem like they can be used for the same things --- except that numpy.maximum can only be used element-wise, while numpy.max and numpy.amax can be used on particular axes, or all elements. Si je veux trouver à la fois max et min, je dois appeler les deux fonctions, ce qui nécessite de passer deux fois sur le (très grand) tableau, ce qui semble lent. numpy.amax() will find the max value in an array, and numpy.amin() does the same for the min value. Input data. numpy max vs amax vs maximum ; pourquoi math.max() renvoie NaN avec un tableau d’entiers? 21. numpy.amax.
