AttributeError: module 'tensorflow' has no attribute 'random_normal'

执行《TensorFlow实战Google深度学习框架(第2版)》only源代码 CH3 时如下语句报错

batch_size = 8
w1= tf.Variable(tf.random_normal([2, 3], stddev=1, seed=1))
w2= tf.Variable(tf.random_normal([3, 1], stddev=1, seed=1))
x = tf.placeholder(tf.float32, shape=(None, 2), name="x-input")
y_= tf.placeholder(tf.float32, shape=(None, 1), name='y-input')

报错如下

1  AttributeError                            Traceback (most recent call last)

      4 x = tf.placeholder(tf.float32, shape=(None, 2), name="x-input")
      5 y_= tf.placeholder(tf.float32, shape=(None, 1), name='y-input')

AttributeError: module 'tensorflow' has no attribute 'random_normal'

解决办法：

tensorflow显示没有random_uniform模块
解决办法：tf2.0里改名字了，用tf.random.uniform代替

2 

module 'tensorflow' has no attribute 'placeholder'

解决方法，更换tensorflow版本，修改方法如下后问题解决

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()
