Tensorflow - CIFAR教程中的导入错误

Question

最近，我安装了tensorflow并在CIFAR教程中得到了python导入错误。
我使用Mac OS X，仅限CPU，Python 2.7。

$ python cifar10_train.py 

Filling queue with 20000 CIFAR images before starting to train. This will take a few minutes.
Traceback (most recent call last):
File "cifar10_train.py", line 120, in
tf.app.run()
File "/Users/sunwoo/tensorflow/lib/python2.7/site-packages/tensorflow/python/platform/app.py", line 30, in run
sys.exit(main(sys.argv[:1] + flags_passthrough))
File "cifar10_train.py", line 116, in main
train()
File "cifar10_train.py", line 76, in train
class _LoggerHook(tf.train.SessionRunHook):
AttributeError: 'module' object has no attribute 'SessionRunHook'

如何导入tf.train.SessionRunHook？

Answer 1

它看起来像你使用的master branch of cifar10_train.py，与旧版本的TensorFlow（0.11或更早版本）。 master分支是recently modified以使用新的API，这在TensorFlow 0.11或更低版本中不可用。

有两种方法可以解决这个问题。将TensorFlow升级到版本0.12或更高版本，或者检出the r0.11 branch of the TensorFlow source，并使用the version of cifar10_train.py from that branch。
