“module”对象没有属性“SummaryWriter”

Question

我在linux CentOS 7上使用Tensorflow 0.12.head版本和Python2.7，运行时：

import tensorflow as tf

a = tf.constant(5, name="input_a")
b = tf.constant(3, name="input_b")
c = tf.mul(a, b, name="mul_c")
d = tf.add(a, b, name="add_d")
e = tf.add(c, d, name="add_e")
sess = tf.Session()
output = sess.run(e)
writer = tf.train.SummaryWriter('./my_graph', sess.graph)

我得到这个错误：

AttributeError                            Traceback (most recent call last) <ipython-input-6-29c037e85eec> in <module>()
----> 1 writer = tf.train.SummaryWriter('./my_graph', sess.graph)

AttributeError: 'module' object has no attribute 'SummaryWriter'

我运行这两个命令是因为Github上有一个bugissue用于相同的问题：

>>> import six
>>> print(six.__version__)
1.10.0
>>> print(dir(six.moves.queue)) ['Empty', 'Full', 'LifoQueue', 'PriorityQueue', 'Queue', '__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '_threading', '_time', 'deque', 'heapq']
>>> print(six.moves.queue.__file__) /usr/lib64/python2.7/Queue.pyc

我是Python和Tensorflow的新手。你知道我怎样才能纠正这个错误吗？

我用FileWriter更改了SummaryWriter：

writer = tf.train.FileWriter('./my_graph', sess.graph)

我得到了同样的错误，但是使用FileWriter函数：

AttributeError                            Traceback (most recent call last)
<ipython-input-8-daa50ea2b8f9> in <module>()
----> 1 writer = tf.train.FileWriter('./my_graph', sess.graph)

AttributeError: 'module' object has no attribute 'FileWriter'

我也在一个终端上运行了它，得到了相同的结果：

在TF的新版本中，allsummary functions were renamed。

Summary functions have been consolidated under the tf.summary namespace.

 Deprecated                                               Replacement

Answer 2

我也遇到了同样的问题…我正在使用pything 3.5.2…请参阅下面的解决方案…希望这对您有用..它确实对我有用（它将在您的tmp文件夹中创建一个日志）：

import tensorflow as tf
a = tf.constant(5, name="input_a")
b = tf.constant(3, name="input_a")
c = tf.multiply(a,b, name="mul_c")
d = tf.add(a,b, name="add_d")
e = tf.add(c,d, name="add_e")

sess = tf.Session()
sess.run(e)
output = sess.run(e)

writer = tf.summary.FileWriter('/tmp/tensorflow_logs', graph=sess.graph)

print(sess.run(e))

Answer 3

不推荐使用tf.train.SummaryWriter，而应使用tf.summary.FileWriter。

↳Adding Summaries to Event Files

It will be removed after 2016-11-30. Instructions for updating: Please switch to tf.summary.FileWriter. The interface and behavior is the same; this is just a rename.
