 问题3：RuntimeError: The Session graph is empty. Add operations to the graph before calling run().

解决方法：tf.compat.v1.disable_eager_execution()

　　　　无法执行sess.run()的原因是tensorflow版本不同导致的，tensorflow版本2.0无法兼容版本1.0.

import tensorflow as tf
print(tf.__version__)

tf.compat.v1.disable_eager_execution() # 保证sess.run()能够正常运行
hello = tf.constant('hello tensorflow!')
sess = tf.compat.v1.Session() # 版本2.0的函数
print(sess.run(hello))

问题4：AttributeError: module 'tensorflow' has no attribute 'mul'

解决方法：tf.mul已经在新版本中被移除，请使用 tf.multiply 代替

问题5：AttributeError: module 'tensorflow' has no attribute 'placeholder'

解决方法：

将

import tensorflow as tf

用以下代码代替

import numpy as np
#import tensorflow as tf
import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

 问题5：Pycharm提示 Unresolved reference 的解决办法

 

解决方法：

有时候a.py和b.py在一个目录里面，但是在a.py种写import b有时会提示Unresolved reference，Pycharm常见。

解决办法是setting -> Project -> Project structure -> Source，点击要加入的文件夹，
** 注意： 添加成功之后该文件见的图标会编程蓝色（加入之前是淡蓝色中间一个圆圈）
