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)
