Windows下安裝完tensorflow后，在cmd下運行python后import tensorflow出現如下錯誤：
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

博主在查找問題解決方案的時候，有說需要安裝Anaconda，我是直接安裝的python3.5.3版本，沒有使用anaconda。又有的說需要安裝visual studio 2017，事實上只是vs2017剛好有運行tensorflow的環境，所以我們需要做的只是安裝缺少的環境即可。在下面的鏈接中下載對應版本（23位和64位），進行安裝就可以。

繼續在cmd下執行python，import tensorflow as tf，不報錯即說明安裝成功啦。
