Import NumPy library: We start by importing the NumPy library which provides support for large multi-dimensional arrays and matrices. Create a 2D array: We create a 2D array array_2d of shape (4, 4) using np.array(). Flatten the array: We use the ravel() method to flatten array_2d i...
This function returns a one-dimensional numpy array which contains all the elements of the input array in the specified order.Example 1Following is the example of Numpy ndarray.flatten() method which shows flattening a 2D array into a 1D array in the default row-major order, resulting in [1...
numpy的reshape和squeeze函数 reshape函数:改变数组的维数(注意不是shape大小) squeeze 函数:从数组的形状中删除单维度条目,即把shape中为1的维度去掉 用法:numpy.squeeze(a,axis = None) a表示输入的数组; axis用于指定需要删除的维度,但是指定的维度必须为单维度,否则将会报错; axis的取值可为None 或 int 或 tu...

>>> import numpy as np >>> y = np.array([[2,3], [4,5]]) >>> y.flatten() array([2, 3, 4, 5]) In the above code a 2D array y is defined with values [2, 3] and [4, 5]. The flatten() method is then called on y which returns a flattened 1D array. Therefore, ...
