python之Windows 8 上的 Tensorflow 安装不起作用

很高兴看到 tensorflow 的 windows 支持。我正在按照 this 上的说明进行操作关联。安装成功,导入时报错。
当我尝试import tensorflow as tf时,以下是回溯

Error importing tensorflow.  Unless you are using bazel, 
you should not try to import tensorflow from its source directory; 
please exit the tensorflow source tree, and relaunch your python interpreter 
from there. 

任何有关解决该问题的建议都将不胜感激。

请您参考如下方法:

此错误消息表示 TensorFlow 依赖的一个或多个 DLL 在您的计算机上不可用。安装 Microsoft Visual C++ 2015 Redistributable Update 3 (x64 version)应该可以解决这个问题。

请注意,如果您安装了 Visual Studio 2015 Update 3 或安装了 Python 3.5 的 Anaconda 发行版,则似乎不会出现此问题。到目前为止,我们只听说过这个问题影响了 Python 3.5 的 Python.org 发行版的用户。我们正在更新文档以反射(reflect)这一点,它应该很快就会可见。
