安装简介

重要！重要！重要！在进行这博文内的安装步骤前，请先查阅我的另一篇博客《Ubuntu 18.04系统净化及环境配置》，按顺序安装里面提到的包，否则后面的安装是不会成功的。

当然了，如果你没有NVIDIA独立显卡，那么你可以直接跳过环境配置的前三条，并在最后安装Caffe前，对Makefile.config中关于前三条的选项（GPU/CUDA/cudnn）进行注释，然后取消CPU的注释即可

安装前的环境配置

下载压缩文件

官方最新下载地址：GitHub地址

如果官网最新的caffe资源无法支持该网页的配置方案，我这里准备了可用的旧版本。点击此处下载旧版

准备压缩文件

将下载好的压缩包提取到当前用户根目录下，并打开该文件夹

修改配置文件

找到Makefile.config.example，并重命名为Makefile.config，详细配置内容可参考下面的信息

为安装matcaffe接口做准备

A：修改Makefile，在该文件411行附近，插入以下命令

CXXFLAGS += -std=c++11

开始安装

cd caffe-master
make all -j
make matcaffe     #若最后一行出现“MEX 已成功完成”，则代表matcaffe接口编译成功
make pycaffe

安装测试

make mattest
make pytest

如果出现以下提示则证明调用matlab接口成功，否则请看系统调整进行修复

Totals:
   7 Passed, 0 Failed, 0 Incomplete.
   0.31512 seconds testing time.

如果出现以下提示则证明调用python接口成功，否则请看系统调整进行修复

Ran 51 tests in 13.732s
OK (skipped=8)

注意，若出现"(skipped=8)"字眼，说明在安装前，没有开启"WITH_PYTHON_LAYER"，若开启之后，这个提示不应该出现

部署pycaffe

A:复制Python接口

在当前用户根目录下打开终端，输入以下命令即可

cp -r caffe-master/python/caffe Anaconda3/lib/python3.6/site-packages

B:添加环境变量

在当前用户根目录下，找到.bashrc文件并打开，在最后添加下面两行文本，保存退出即可

# added by python caffe interface
export LD_LIBRARY_PATH="$HOME/caffe-master/build/lib:$LD_LIBRARY_PATH"

C:运行测试

重启终端后，进入python环境，输入以下命令，如果能正常加载caffe，则部署成功

python中的caffe加载测试图

系统调整

根据提示，缺了哪个就执行哪个命令即可

sudo ln -sf /usr/lib/x86_64-linux-gnu/libstdc++.so.6    /usr/local/MATLAB/R2014a/bin/glnxa64
sudo ln -sf /usr/local/cuda-8.0/lib64/libcublas.so.8.0  /usr/local/MATLAB/R2014a/bin/glnxa64
sudo ln -sf /usr/local/cuda-8.0/lib64/libcudart.so.8.0  /usr/local/MATLAB/R2014a/bin/glnxa64
sudo ln -sf /usr/local/cuda-8.0/lib64/libcudnn.so.5     /usr/local/MATLAB/R2014a/bin/glnxa64

如果本篇文章能让你成功安装该套配置，请顺手点个赞，毕竟这篇文章我重装了N次系统和工具才完成的。。
