Keras導入錯誤Tensorflow後端

Question

--------------------------------------------------------------------------- 
ImportError        Traceback (most recent call last) 
/Users/CJL/anaconda3/lib/python3.5/site-packages/keras/backend/tensorflow_backend.py in <module>() 
     4 try: 
----> 5  from tensorflow.python.ops import ctc_ops as ctc 
     6 except ImportError: 

ImportError: cannot import name 'ctc_ops' 

During handling of the above exception, another exception occurred: 

ImportError        Traceback (most recent call last)

    70 else: 
    71  raise Exception('Unknown backend: ' + str(_BACKEND))

     5  from tensorflow.python.ops import ctc_ops as ctc 
     6 except ImportError: 
----> 7  import tensorflow.contrib.ctc as ctc 
     8 
     9 import numpy as np 

ImportError: No module named 'tensorflow.contrib.ctc' 

好像是Keras的問題，並根據這個帖子enter link description here 如果這已經未定我在想，不Tensorflow？

Answer 1

這是Keras和張量流之間的問題。你應該改變這種fix使用類似

if hasattr(tf.contrib, 'ctc'): 
    ctc = tf.contrib.ctc # old version 
else: 
    ctc = tf.nn # New official version. 

目前的「官方」的方式來訪問CTC操作都在tf.nn，例如，tf.nn.ctc_loss。
