By default, the index is into the flattened array, else along the specified axis. Parameters. Si vous avez une préférence, il suffit de commander les entrées max … Quel est le moyen le plus simple d'étendre un tableau numpy en 2 dimensions? The numpy.argmax() function returns indices of the max element of the array in a particular axis.. Syntax : numpy.argmax(array, axis = None, out = None) Parameters : array : Input array to work on axis : [int, optional]Along a specified axis like 0 or 1 out : [array optional]Provides a feature to insert output to the out array and it should be of appropriate shape and dtype Axis or axes along which to operate. Syntax: numpy.amax(arr, axis = None, out = None, keepdims = ) Parameters – arr : [array_like] input data; axis : [int or tuples of int] axis along which we want the max value. numpy.amin() and numpy.amax() These functions return the minimum and the maximum from the elements in the given array along the specified axis. Python Tutorials. 2.1 Import; 2.2 Création d’objets ndarray. 1.3 Numpy; 1.4 Numpy vs Matlab / Octave; 2 Description de Numpy. numpy.maximum¶ numpy.maximum (x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True [, signature, extobj]) = ¶ Element-wise maximum of array elements. The input is of type int. You’ll understand how to find and fill missing values, reshape an array, delete excess data as well as sort, shuffle and cast ndarrays. Example. numpy.amax() will find the max value in an array, and numpy.amin() does the same for the min value. Tạo câu hỏi [IT ] Đã hỏi 5 năm trước.
