Win10下部署TensorFlow以及一些避坑小指南
第一步，下载Anaconda3
Anaconda官网目前最新的版本是Python3.6的，想要历史版本的，去下面的网站下载：
/
我们下载了支持Python3.5.2的Anaconda3-4.2.0版本
Anaconda3-4.2.0-Windows-x86_64.exe
安装后查看是否安装成功
C:\Users\yuhul>python
Python 3.5.2 |Anaconda 4.2.0 (64-bit)| (default, Jul 5 2016, 11:41:13) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>第二步，需要升级一下pip
C:\Users\yuhul>python -m pip install --upgrade pip
Collecting pipUsing cached pip-9.0.1-py2.py3-none-any.whl
Installing collected packages: pipFound existing installation: pip 8.1.2Uninstalling pip-8.1.2:Successfully uninstalled pip-8.1.2
Successfully installed pip-9.0.1第三步，安装CUDA
1.检查兼容性
首先要确保自己的显卡支持CUDA，这个需要是NVIDIA的显卡，可以去这个网址查查
例如我的笔记本显卡是GeForce GTX 850M就可以，如下图
2.CUDA8.0下载安装（官方建议版本）
下载地址如下：
选好自己的操作系统，我的是Win10，于是Version选择10
官网下载速度非常快，强烈推荐，下载完毕后，直接安装
中间准备安装的时候会删除旧的驱动，安装一些新的驱动和依赖，比如Visual Studio
3.检查是否安装成功
安装完毕，检查一下，OK
C:\Users\yuhul>nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2016 NVIDIA Corporation
Built on Mon_Jan__9_17:32:33_CST_2017
Cuda compilation tools, release 8.0, V8.0.60第四步，准备cuDNN
下载cuDNN5.1（官方建议版本），需要简单注册一下，下载地址如下：
注册、认证、改密码三个步骤，大约需要3-5分钟左右，如果觉得麻烦，也可以去百度网盘下载，文件不是很大，地址如下：
链接： 密码：ivo0
将压缩文件解压到D盘下，解压包就在D:\cuda目录下，注意需要将D:\cuda\bin加入Path环境变量，不然会报错。下面的避坑指南里面专门说明这个。
第五步，pip安装TensorFlow
安装命令如下
pip install --upgrade tensorflow-gpu安装成功后，会有类似下面的信息提示。
Successfully installed protobuf-3.3.0 tensorflow-gpu-1.1.0 werkzeug-0.12.2
测试一下
>>> import tensorflow as tf
>>>
>>> a = tf.random_normal((100, 100))
>>> b = tf.random_normal((100, 500))
>>> c = tf.matmul(a, b)
>>> sess = tf.InteractiveSession()

>>> sess.run(c)

下面是一些小坑
1. 升级setuptools

You are using pip version 8.1.2, however version 9.0.1 is available.

>>>后面将cuda加入Path环境变量，例如我的目录是D:\cuda\bin，问题解决。
第一次运行的时候，会有一些提示信息，
The TensorFlow library wasn’t compiled to use (SSE, SSE2, SSE3, SSE4.1, SSE4.2, AVX, AVX2, FMA)instructions, but these are available on your machine and could speed up CPU computations。
第二次再运行的时候就没有了。
具体如下：
