Parameters: a: array_like. Miksi siellä on enemmän kuin vain numpy.max?Onko tässä esityksessä hienovaraisuutta? This causes a lot of bugs (also for my colleague who thought, too, that min and max would work like Python's min and max … numpy.amax. and calling max(2, 3) (which would work in Python) the numpy version returns 2 (always the first argument) without complaining that I didn't pass an array. numpy max vs amax vs max numpy có ba hàm khác nhau có vẻ như chúng có thể được sử dụng cho cùng một thứ --- ngoại trừ việc numpy.maximum có thể chỉ được sử dụng phần tử khôn ngoan, trong khi numpy.max và numpy.amax có thể được sử dụng trên các trục cụ thể hoặc tất cả các yếu tố.
