--------------------------------------------------------------------------- 
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:

----> 7  import tensorflow.contrib.ctc as ctc

     9 import numpy as np 

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

이 보인다?

Answer 1

이것은 Keras와 tensorflow 사이의 문제입니다. 이 fix이 tf.nn.ctc_loss는 예를 들어, 캐나다 관광청 작업 tf.nn에 액세스 할 수

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

처럼 현재의 "공식"방식으로 뭔가를 사용하여 변경해야합니다.
