windows安装caffe

比较靠谱的博客：
https://blog.csdn.net/qq_42722197/article/details/122749759

2022.3.29安装完毕，如果有朋友有问题可在评论区提问（不要私信，csdn私信广告太多，楼主不看私信）

1、环境要求：
Anaconda,并创建python3.5版本的环境，并将该环境加入到环境变量(只能创建python3.5或者2.7的，其他的都不行，楼主用的3.5)

ninja：安装地址https://github.com/ninja-build/ninja/releases
注意：ninja-win.zip和Source code都要下载，并且将解压ninja-win后得到的ninja.exe放入Source code解压后的文件夹里，并将该文件夹添加到环境变量

Visual Studio 2015：自行安装，并添加到环境变量
cmake：自行安装最新版本（若安装了Anaconda，则可能自带的有，可以查找看看），并添加到环境变量

2、环境准备完毕后，按照官方地址https://github.com/BVLC/caffe/tree/windows所给安装方法,
依次执行

git clone https://github.com/BVLC/caffe.git
cd caffe
git checkout windows

在执行 scripts\build_win.cmd前，修改scripts文件夹下的build_win.cmd文件（用记事本打开即可）。修改其中配置如下（注意是用ninja安装的，所以和网上大部分配置有所不同，且需要修改的地方很多，楼主就不一一指出了）：

其中

改成你的python环境路径（理论上说不改也没有影响）

3、保存 build_win.cmd文件，并执行

 scripts\build_win.cmd

这部分bug是最多的，一些楼主遇到的bug详见文末
4、完成编译之后，手动把caffe\python下的caffe文件夹整个拷贝到你的python环境的Lib文件夹下的site-packages里面，如F:\Anaconda\file\envs\python35\Lib\site-packages

5、运行python3.5,import caffe，大功告成

一些坑:
1、新建环境变量后，cmd需重启才有效
2、报错：无法打开包括文件: “caffe/include_symbols.hpp”
解决方法：找到并打开export.hpp，将里面include caffe/include_symbols.hpp改成include include_symbols.hpp
（根据楼主观察，caffe在编译前几个文件时又会改成include caffe/include_symbols.hpp，需要在编译几个文件后做修改并保存）
3、要提前在python3.5的环境里安装好numpy scipy protobuf==3.1.0 six scikit-image pyyaml pydotplus graphviz
如果有pip可以运行

pip install numpy scipy protobuf==3.1.0 six scikit-image pyyaml pydotplus graphviz

4、一定要确保在cmd里敲击python、ninja、cl不会报错‘xxx’不是内部或外部命令，也不是可运行的程序，即这些文件都在环境变量里，且python版本一定要正确（可在cmd里敲击python后查看python版本）

5、报错ninja: build stopped: subcommand failed.
注意查看上面输出信息里的fatal error（要仔细找），看看里面写的什么，那个才是真正的报错原因

6、报错No CMAKE_CXX_COMPILER could be found. 注意ninja是否在环境变量里，且 if NOT DEFINED WITH_NINJA set WITH_NINJA=1（不是0）

7、‘cmake’ 不是内部或外部命令,也不是可运行的程序
确保cmake在环境变量里，若不在，请先自行百度解决方法

8、Could not find url for MSVC version = 1900 and Python version = 3.7.
python版本不是3.5，打开cmd输入python --version，查看版本。若版本不对，用Anaconda新建环境，并将新建环境添加到环境变量，具体可参考文章开头的第一步

9、The dependency target "pycaffe" of target "pytest" does

没有安装numpy

10、Unsupported gpu architecture ‘compute_20’
没有设置CPU_ONLY为1，以及cuda相关配置为0，参考文章中所给的配置选项
