基础知识整理
x_data = np.random.rand(100).astype(np.float32)
np.random.rand() 返回一个或一组服从“0~1”均匀分布的随机样本值。随机样本取值范围是[0,1),不包括1。
np.random.randn() 返回一个或一组服从标准正态分布的随机样本值。
import tensorflow as tf
import numpy as np
x = np.random.rand(5).astype(np.float32)
print(x)
y = np.random.rand(3,1).astype(np.float32)
print(y)
z = np.random.rand(3,3).astype(np.float32)
print(z)
