本文实例讲述了Python3.5 win10环境下导入keras/tensorflow报错的解决方法。分享给大家供大家参考，具体如下：
我在win10 Python3.5.2安装keras，然后导入时报错如下：
Python 3.5.2 |Continuum Analytics, Inc.| (default, Jul 5 2016, 11:41:13) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import keras
Using TensorFlow backend.

又臭又长的问题说导入keras时先导入TensorFlow，然后出现导入失败，解决方法有两个：
一.安装Microsoft Visual C++ 2015 Redistributable Update 3
先在https://www.microsoft.com/en-us/download/details.aspx?id=53587
下载Microsoft Visual C++ 2015 Redistributable Update 3。
然后安装。
接下来重启电脑，然后卸载tensorflow：
pip uninstall tensorflow pip uninstall tensorflow-gpu
然后再重装：
pip install tensorflow pip install tensorflow-gpu
再重新导入应该不会报错了。
如果无法解决，看下面的方法：
二.cmd下敲命令：
pip install --upgrade --ignore-installed setuptools
