Windows下安装完tensorflow后，在cmd下运行python后import tensorflow出现如下错误：
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

博主在查找问题解决方案的时候，有说需要安装Anaconda，我是直接安装的python3.5.3版本，没有使用anaconda。又有的说需要安装visual studio 2017，事实上只是vs2017刚好有运行tensorflow的环境，所以我们需要做的只是安装缺少的环境即可。在下面的链接中下载对应版本（23位和64位），进行安装就可以。

继续在cmd下执行python，import tensorflow as tf，不报错即说明安装成功啦。
