Windows 8上的Tensorflow安装不起作用

Question

我很高兴看到张量流的Windows支持。我遵循this链接上的说明。安装成功，但在导入时会生成错误。
当我尝试import tensorflow as tf，下面是回溯

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. 

上解决这个问题的任何指针将不胜感激。

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，则不会出现此问题。到目前为止，我们只听说过影响Python 3.5 Python.org发行版的用户的这个问题。我们正在更新文档以反映这一点，并且应该很快显现。
