WitrynaSuppose img is a (32,32,3) array, representing a 32x32 image with 3 color channels red, green and blue. How do you reshape this into a column vector? x = img.reshape((3,32*32)) Witrynax = img.reshape((3,32*32)) x = img.reshape((32*32,3)) 4. Consider the two following random arrays "a" and "b": What will be the shape of "c"? Correct Yes! This is broadcasting. b (column vector) is copied 3 times so that it can be summed to each column of a. 1 / 1 points c.shape = (2, 3) c.shape = (3, 2) a = np.random.randn(2, 3) # … Witryna13 mar 2024 · 和y坐标，其中x坐标在0到1之间均匀分布，y坐标为x的平方。 可以使用以下代码生成这些数据点： ```python import numpy as np x = np.linspace(0, 1, 1000) y = x ** 2 data = np.column_stack((x, y)) ``` 这里使用了NumPy库中的linspace函数生成0到1之间的1000个均匀分布的x坐标，然后计算每个x坐标对应的y坐标，最后使 … chs phone call
