NumPy: Get the number of dimensions, shape, and size of ndarray
WebbThe shape property is usually used to get the current shape of an array, but may also be used to reshape the array in-place by assigning a tuple of array dimensions to it. As with numpy.reshape , one of the new shape dimensions can be -1, in which case its value is … numpy.ndarray# class numpy. ndarray (shape, dtype = float, buffer = None, … Feature. Type. Notes.
