前言

主要是解决由于1.0版本和2.0版本代码实现不同造成的报错

报错一：cannot import name 'Adam' from'keras.optimizers'

报错语句：from keras.optimizers import Adam
正确语句：from keras.optimizers import adam_v2

报错二：module 'tensorflow' has no attribute 'app'

 报错语句：

import tensorflow as tf
flags =tf.app.flags
FLAGS = flags.FLAGS

正确语句：

import tensorflow.compat.v1 as tf
flags=tf.app.flags
FLAGS = tf.app.flags.FLAGS

报错三：No module named 'tensorflow.contrib'

 报错语句：import tensorflow.contrib.keras as kr

正确语句：import keras as kr

报错四： module 'tensorflow' has no attribute 'placeholder'

错误代码：import tensorflow as tf
正确代码：
import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()
tf.compat.v1.disable_eager_execution()

但是改之后出现错误五

 报错五：module 'tensorflow.compat.v1' has no attribute 'contrib'

错误代码：Cell = tf.contrib.rnn.DropoutWrapper(cell, self.keep_pro)

正确代码：Cell =tf.nn.rnn_cell.DropoutWrapper(cell, self.keep_pro)

（此时tf=tensorflow.compat.v1）

报错六： module 'tensorboard.summary._tf.summary' has no attribute 'merge_all'

错误语句：import tensorflow as tf 

正确语句：import tensorflow.compat.v1 as tf

报错七：module 'tensorflow' has no attribute 'Session'

 解决同六

报错八：module 'keras.utils' has no attribute 'to_categorical'

 错误语句：

import keras as kr
y_pad = kr.utils.to_categorical(label_id)

正确语句：

import tensorflow as tf
y_pad = tf.keras.utils.to_categorical(label_id)

遇到版本不一致问题，可以直接到官网搜索对应的函数，会出来相应的导入路径
