的Bug tensorflow tuttorial與量化

這篇文章跟隨我的另一篇文章關於運未註冊： NotFoundError: Op type not registered 'Dequantize'的Bug tensorflow tuttorial與量化

，現在當我嘗試加載手動在這個帖子： Install Tensorflow with Quantization Support

有：

qops = tf.load_op_library('/home/artem/projects/tensorflow/bazel-bin/tensorflow/contrib/quantization/_quantized_ops.so') 
qkernelops = tf.load_op_library('/home/artem/projects/tensorflow/bazel-bin/tensorflow/contrib/quantization/kernels/_quantized_kernels.so')

我得到以下錯誤：

--------------------------------------------------------------------------- 
NotFoundError        Traceback (most recent call last) 
<ipython-input-4-799f99708cda> in <module>() 
     1 
----> 2 qops = tf.load_op_library('/home/artem/projects/tensorflow/bazel-bin/tensorflow/contrib/quantization/_quantized_ops.so') 
     3 qkernelops = tf.load_op_library('/home/artem/projects/tensorflow/bazel-bin/tensorflow/contrib/quantization/kernels/_quantized_kernels.so') 

/usr/local/lib/python2.7/dist-packages/tensorflow/python/framework/load_library.pyc in load_op_library(library_filename) 
    69   return _OP_LIBRARY_MAP[library_filename] 
    70  # pylint: disable=protected-access 
---> 71  raise errors._make_specific_exception(None, None, error_msg, error_code) 
    72  # pylint: enable=protected-access 
    73 finally: 

NotFoundError: /home/artem/projects/tensorflow/bazel-bin/tensorflow/contrib/quantization/_quantized_ops.so: undefined symbol: _ZN10tensorflow8internal21CheckOpMessageBuilder9NewStringB5cxx11Ev

它看起來像它與C++編譯器有問題，也許我應該補充-D_GLIBCXX_USE_CXX11_ABI=0在這個帖子： https://github.com/tensorflow/tensorflow/pull/1584

，但我其實bazel-build，我不知道如何管理它。

有人可以幫助我嗎？來自https://www.tensorflow.org/versions/master/how_tos/quantization/index.html的測試示例也不起作用。如果有人會寫出關於量化的詳細手冊，那將會很棒。

聽起來像github問題的好主題，提@petewarden –

謝謝你的建議。我在這裏創建它： https://github.com/tensorflow/tensorflow/issues/3533 –

Tensorflow 0.10發佈了！我在更新後解決了這個問題！在腳本中添加這些代碼：

from tensorflow.contrib.quantization import load_quantized_ops_so 
from tensorflow.contrib.quantization.kernels import load_quantized_kernels_so

和

load_quantized_ops_so.Load() 
load_quantized_kernels_so.Load()

感謝TF團隊！
