**caffe_vcpkg+vs2017+win7安装整理**

caffe_vcpkg+vs2017+win7安装整理

1.前期准备

（1）python3.5->Anaconda3_64（caffe只支持python2.7和3.5）：
可先查当前python版本，通过命令行键入“python –version”，即可查看当前python版本。
若是没有3.5或者2.7的话借助Anaconda3安装就好了，若是不想借助Anaconda3安装也可以去官网下载python3.5或者2.7安装包进行安装。

（2）caffe源码：https://github.com/willyd/caffe/tree/vcpkg

（3）python3.5的OpenCV-python:pip install opencv-python（在第一个条件满足的前提下安装）

2.开始安装

/一定要按照源码网址那样的安装/
(1)下载源码（windows）
打开命令行（cmd）
cd 这里输入你想要安装的位置
git clone https://github.com/BVLC/caffe.git
cd caffe
git checkout windows
等到git clone完成，进入第二步

（2）修改caffe/scripts/build_win.cmd内容
下面的语句修改，具体根据个人的需求，每一个指令的具体用处请看https://github.com/willyd/caffe/tree/vcpkg
篮字为具体修改的地方，以下为具体的修改内容

else (
:: Change the settings here to match your setup
:: Change MSVC_VERSION to 12 to use VS 2013
if NOT DEFINED MSVC_VERSION set MSVC_VERSION=15
:: Change to 1 to use Ninja generator (builds much faster)
if NOT DEFINED WITH_NINJA set WITH_NINJA=0
:: Change to 1 to build caffe without CUDA support
if NOT DEFINED CPU_ONLY set CPU_ONLY=1
:: Change to generate CUDA code for one of the following GPU architectures
:: [Fermi Kepler Maxwell Pascal All]
if NOT DEFINED CUDA_ARCH_NAME set CUDA_ARCH_NAME=Auto
:: Change to Debug to build Debug. This is only relevant for the Ninja generator the Visual Studio generator will generate both Debug and Release configs
if NOT DEFINED CMAKE_CONFIG set CMAKE_CONFIG=Release
:: Set to 1 to use NCCL
if NOT DEFINED USE_NCCL set USE_NCCL=0
:: Change to 1 to build a caffe.dll
if NOT DEFINED CMAKE_BUILD_SHARED_LIBS set CMAKE_BUILD_SHARED_LIBS=0
:: Change to 3 if using python 3.5 (only 2.7 and 3.5 are supported)
if NOT DEFINED PYTHON_VERSION set PYTHON_VERSION=3
:: Change these options for your needs.
if NOT DEFINED BUILD_PYTHON set BUILD_PYTHON=1
if NOT DEFINED BUILD_PYTHON_LAYER set BUILD_PYTHON_LAYER=1
if NOT DEFINED BUILD_MATLAB set BUILD_MATLAB=0
:: If python is on your path leave this alone
if NOT DEFINED PYTHON_EXE set PYTHON_EXE=python
:: Run the tests
if NOT DEFINED RUN_TESTS set RUN_TESTS=0
:: Run lint
if NOT DEFINED RUN_LINT set RUN_LINT=0
:: Build the install target
if NOT DEFINED RUN_INSTALL set RUN_INSTALL=1
)

:: Set the appropriate CMake generator
:: Use the exclamation mark ! below to delay the
:: expansion of CMAKE_GENERATOR
if %WITH_NINJA% EQU 0 (
if “%MSVC_VERSION%”==”15” (
set CMAKE_GENERATOR=Visual Studio 15 2017 Win64
)
if “%MSVC_VERSION%”==”14” (
set CMAKE_GENERATOR=Visual Studio 14 2015 Win64
)
if “%MSVC_VERSION%”==”12” (
set CMAKE_GENERATOR=Visual Studio 12 2013 Win64
)
if “!CMAKE_GENERATOR!”==”” (
echo ERROR: Unsupported MSVC version
exit /B 1
)
) else (
set CMAKE_GENERATOR=Ninja
)

(3)修改
caffe/cmake/WindowsDownloadPrebuiltDependencies.cmake内容

—–>WindowsDownloadPrebuiltDependencies.cmake内修改如下（除了篮字外的其他地方不用修改，加上蓝色那一句话就好了）：

set(MSVC_VERSION 1900)
if(NOT DEFINED DEPENDENCIES_URL_{MSVC_VERSION}_{MSVC_VERSION}_{MSVC_VERSION}_{_pyver})
message(FATAL_ERROR “Could not find url for MSVC version = MSVCVERSIONandPythonversion=MSVCVERSIONandPythonversion={MSVC_VERSION} and Python version = {PYTHON_VERSION_MAJOR}.${PYTHON_VERSION_MINOR}.”)
endif()

(4)命令行进入caffe/scripts文件夹,直接命令行输入build_win.cmd运行就可以了
等待编译成功，修改build_win.cmd把Debug和Realease都生成了，编译caffe.sln成功即可

（5）配置C++链接库
参考网址：根据不带源码的方式配置
https://blog.csdn.net/chris_zhangrx/article/details/79234568

（6）需要的话也可以配置一下python的
参考网址
https://blog.csdn.net/chris_zhangrx/article/details/79210288

问题解决：

（1）按照以上的每一个步骤配置完成后，测试时若是出现若出现“错误：LNK1104 libboost_date_time-vc141-mt-gd-x64-1_67.lib”则解决方法，右键属性——C/C++——代码生成——运行库，改为多线程调试 DLL (/MDd)，可以运行即可

（2）若是出现
caffe/include/caffe/proto/caffe.pb.h:17:2: error: #error This file was generated by an older version of protoc which is
#error This file was generated by an older version of protoc which is
^
caffe/include/caffe/proto/caffe.pb.h:18:2: error: #error incompatible with your Protocol Buffer headers. Please
#error incompatible with your Protocol Buffer headers. Please
^
/usr/local/caffe/include/caffe/proto/caffe.pb.h:19:2: error: #error regenerate this file with a newer version of protoc.
#error regenerate this file with a newer version of protoc.

那么找到caffe.pb.h，找到以下字样

注意到有一串数字2006001，那代表的是protobuf的版本应该是2.6.1高于或者低于它都不行，若是3001000,那代表对应的protobuf版本的就是3.1版本，我的解决方法是，根据https://blog.csdn.net/qing666888/article/details/79137963安装好对应版本后，把生成的Debug文件夹内的所有lib复制黏贴到C:\Windows\System32和C:\Windows\SysWOW64下，重新运行build_win.cmd即可安装完成

成功了，鼓掌
心里话：一直想要写博客，帮帮跟我有一样的需求，但是找不到资料，又出现各种问题的各位，故小心翼翼写下这篇博客，这是我的第一篇博客，不足之处，还请各位大佬指出，若是能帮到各位，那就够了。
