win10 + gtx1060 + cuda8.0 + caffe + vs2013 + Tensorflow + PyTorch

一. 安装cuda8.0

1)先去官网下载cuda8.0  https://developer.nvidia.com/cuda-toolkit

2)下载完之后进行安装，安装时间有点长，请耐心等待，默认是安装在c盘目录下

　安装完后会生成两个系统变量：

CUDA_PATH    C:Program FilesNVIDIA GPU Computing ToolkitCUDAv8.0
CUDA_PATH_V8_0    C:Program FilesNVIDIA GPU Computing ToolkitCUDAv8.0

3)测试是否成功 : 进入cmd，输入 nvcc -V 命令，如图所示

表示cuda安装成功

4)进入sdk实例安装目录

C:ProgramDataNVIDIA CorporationCUDA Samplesv8.0

点击Samples_vs2013.sln文件打开vs2013执行 

运行Samples_vs2013.sln文件就会出现如图所示

表明测试成功

或者试试

nvcc -V

二. 下载安装CAFFE

1)拷贝 .windowsCommonSettings.props.example 到 .windowsCommonSettings.props

默认情况下Windows版本caffe需要 CUDA 和 cuDNN 库，你也可以在.windowsCommonSettings.props 里禁用他们。

默认情况下matlab/Python支持被没有开启的，你也可以通过修改 .windowsCommonSettings.props 来启用。

2)如果你不需要CUDA，你可以安装CPU_ONLY版本：编辑文件.windowsCommonSettings.props，设置CpuOnlyBuild 为 true，UseCuDNN为false。

3)cuDNN V5 下载 （不使用可以跳过）

解压下载的zip文件到 %CUDA_PATH% (这个环境变量是由上一步安装的CUDA设置的)。或者你也可以解压到任何位置， 然后再 .windowsCommonSettings.props 里设置 CuDnnPath 来指向解压到的目录。

你可以修改.windowsCommonSettings.props文件，设置 UseCuDNN 为 false 来禁用cuDNN。

https://developer.nvidia.com/rdp/cudnn-download

4)Python

为了编译Caffe Python封装库，需要.windowsCommonSettings.props文件，设置 PythonSupport为 true。

下载 Anaconda2 64-bit Windows installer： Anaconda2 。

安装完后我们需要将.windowsCommonSettings.props 中python PythonDir 改成我们自己的

接下来安装 google.protoc

编译python支持库后，你还需要执行如下之一才能在python里使用：

• 设置环境变量 PythonPath，值为 <caffe_root>Buildx64Releasepycaffe，或者
• 复制目录 <caffe_root>Buildx64Releasepycaffecaffe 到 <python_root>libsite-packages 目录

注意：python 不存在debug库

5).Matlab

编译Matlab支持，修改.windowsCommonSettings.props文件，设置 MatlabSupport 为true，MatlabDir 为 Matlab安装根目录。

    </PropertyGroup>
    <PropertyGroup Condition="'$(MatlabSupport)'=='true'">
        <MatlabDir>C:Program FilesMATLABR2014a</MatlabDir>
        <LibraryPath>$(MatlabDir)externlibwin64microsoft;$(LibraryPath)</LibraryPath>
        <IncludePath>$(MatlabDir)externinclude;$(MatlabDir);$(IncludePath)</IncludePath>
    </PropertyGroup>

 

注意：最近Microsoft 的github貌似更新了matcaffe中的caffe_.cpp文件，第十六行添加了对 gpu/mxGPUArray.h 的引用

修改matcaffe中的第十六行 #include"gpu/mxGPUArray.h" 中修改为

#include<toolbox/distcomp/gpu/extern/include/gpu/mxGPUArray.h>

编译Matlab支持库后，你还需要执行如下操作才能在matlab里使用：

• 添加生成的 matcaffe 目录到 Matlab 搜索路径，
• 添加 <caffe_root>Buildx64Debug 到 系统环境变量 PATH(不一定需要）

6）打开 Caffe.sln 解决方案

第三方Caffe依赖库被自动通过NuGet安装:

右键工程-》管理NuGet程序包，还原所有的包。原始使用的opencv是2.4.10版本（我卸掉它使用opencv3.1）. 所有包会下载到

C:UsersAdministratorAppDataLocalNuGetCache

这里是清单:

如果你将opencv改成了3.1注意要删除每个项目文件下 *.vcxproj 里有关opencv2.4.10的加载失败错误项。

如果某个包下载不了。。。那就参考这个吧

在项目中打开 工具->NuGet程序包管理器->控制台，并输入命令：Install-Package fluentnhibernate ，进行安装。

Install-Package boost_regex-vc120 -version 1.59 -Source C:UsersAdministratorAppDataLocalNuGetCache 

7)编译

现在你可以开始编译工程文件了： .windowsCaffe.sln

注意要先编译 libcaffe, 同时编译python时只能选Release

8)为了以后使用方便，我们将生成的exe路径放入环境目录path里

C:caffe-master2Buildx64Debug

9) 为了使用caffe的sh脚本文件，我们需要安装 Git 和 wgetwin (将wget.exe放入C:WindowsSystem32)

三. 安装Tensorflow

之前安装过python2.7，可是为了学习tensorflow，这里要安装下python3.5

1.首先，去下载地址（下载包含python3.5版本的Anaconda）

2. 安装过程和anaconda2类似，但是，安装的路径要设置在anaconda2的envs文件夹下，另起名，我起名为py3.

安装过程的不同之处在下图：

 将环境变量修改了（安装结束后再改回去），然后

conda install ipython
conda install jupyter

3.完成后，检查是否安装成功，首先，cmd输入python，显示的之前的python版本（之前默认的是python版本）

python -V

我们想用3.5版本就需要激活，命令：

activate py3

4.安装Tensorflow

pip install setuptools --ignore-installed

  这是指定安装tensorflow版本方式

pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-1.2.1-cp36-cp36m-win_amd64.whl

这是利用conda安装方式，这种方式需要将环境变量修改了（安装结束后再改回去）

conda install -c https://conda.anaconda.org/jjhelmus tensorflow-gpu

 这是官方建议的安装方式，会安装最新版

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --upgrade tensorflow-gpu

因为不同的版本对应着不同的cudnn所以用脚本 tensorflow_self_check.py 检查一遍

测试

import tensorflow as tf    
h = tf.constant('Hello, Tensorflow!')    
s = tf.Session()    
print(s.run(h))  

关闭3.5：

deactivate py3

四. 安装keras

pip install bcolz

 如果安装有问题，就下载安装吧

pip install keras

安装结束后在此新建

C:UsersMyPC.keraskeras.json

这个文件中可以指定使用tensorflow还是theano

{
    "image_dim_ordering": "tf",
    "epsilon": 1e-07, 
    "floatx": "float32", 
    "image_data_format": "channels_last", 
    "backend": "tensorflow"
}

{
    "image_dim_ordering": "th",
    "floatx": "float32",
    "epsilon": 1e-07,
    "backend": "theano",
    "image_data_format": "channels_last"
}

五. 安装PyTorch

安装官方建议：

conda install pytorch torchvision -c pytorch

但往往。。。安装pythorch的时候下载慢的一比，因此可以考虑离线安装

https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/win-64/

 安装完以后可以验证下

import torch
import torchvision
print(torch.__version__)
print(torch.cuda.is_available())

简单练习
