utuntu16.04安装caffe+Matlab2017a+opencv3.1+CUDA8.0+cudnn6.0

• 上午把tensorflow安装好了，下午和晚上装caffe的确很费劲。
• 默认CUDA,cuDNN可以用了
• caffe官方安装教程
• 有些安装顺序自己也不清楚，简直就是碰运气

1. 安装之前依赖项

General dependencies

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler
sudo apt-get install --no-install-recommends libboost-all-dev

安装matlab见后面：

为什么需要安装Matlab？
caffe有Matlab的接口，因此如果需要使用Matlab调用caffe，进行编程，就需要安装Matlab。如果你觉得使用C或Python编程比较难，就请安装Matlab。当然如果不需要，并且后面不会编译caffe生成Matlab的接口，就不需要安装Matlab了。这个纯粹根据个人需求来定。


为什么需要安装OpenCV？
caffe是用来做深度学习的，深度学习的一大应用对象就是图像和视频。而OpenCV是目前最火的开源计算机视觉库，非常多的项目多用到了OpenCV，当然caffe也依赖OpenCV。所以，需要安装OpenCV，否则无法使用caffe哦

OpenCV的版本和cuda的版本最好匹配。这样子安排的目的是为了减少错误出现的概率

2.OpeCV安装

从官网(http://opencv.org/downloads.html)下载Opencv,并将其解压到你要安装的位置，假设解压到了/home/opencv。 安装前准备，创建编译文件夹：

cd ~/opencv
mkdir build
cd build

配置：

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..

编译：

make -j8  #-j8表示并行计算，根据自己电脑的配置进行设置，配置比较低的电脑可以将数字改小或不使用，直接输make。

以上只是将opencv编译成功，还没将opencv安装，需要运行下面指令进行安装：

sudo make install

问题：由于CUDA 8.0不支持OpenCV的 GraphCut 算法，可能出现以下错误：

/home/dsp/opencv-3.1.0/modules/core/include/opencv2/core/private.cuda.hpp:165:52: note: in definition of macro ‘nppSafeCall’
 #define nppSafeCall(expr)  cv::cuda::checkNppError(expr, __FILE__, __LINE__, CV_Func)
                                                    ^
modules/cudalegacy/CMakeFiles/opencv_cudalegacy.dir/build.make:146: recipe for target 'modules/cudalegacy/CMakeFiles/opencv_cudalegacy.dir/src/graphcuts.cpp.o' failed
make[2]: *** [modules/cudalegacy/CMakeFiles/opencv_cudalegacy.dir/src/graphcuts.cpp.o] Error 1
make[2]: *** 正在等待未完成的任务....
CMakeFiles/Makefile2:9226: recipe for target 'modules/cudalegacy/CMakeFiles/opencv_cudalegacy.dir/all' failed
make[1]: *** [modules/cudalegacy/CMakeFiles/opencv_cudalegacy.dir/all] Error 2
make[1]: *** 正在等待未完成的任务....
[ 92%] Linking CXX shared library ../../lib/libopencv_photo.so
[ 92%] Built target opencv_photo
Makefile:160: recipe for target 'all' failed
make: *** [all] Error 2

进入opencv-3.1.0/modules/cudalegacy/src/目录，修改graphcuts.cpp文件，将：

#include "precomp.hpp"

#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER)

改为

#include "precomp.hpp"

#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER) || (CUDART_VERSION >= 8000)

然后make编译就可以了

- 编译和安装完成

装BLAS

这里可以选择（ATLAS，MKL或者OpenBLAS）：不知道这个，下载有问题，所以就没有搞这个，但是makefile.config文件里面有配置

MKL首先下载并安装英特尔® 数学内核库 Linux* 版MKL(Intel(R) Parallel Studio XE Cluster Edition for Linux 2016)，下载链接是：https://software.intel.com/en-us/qualify-for-free-software/student， 使用学生身份（邮件 + 学校）下载Student版，填好各种信息，可以直接下载，同时会给你一个邮件告知序列号。

后面就直接：sudo apt-get install libatlas-base-dev -y  

sudo apt-get install libatlas-base-dev 

 3.MATLAB2017a安装

• utuntu2017a安装:http://blog.csdn.net/u011713358/article/details/69659265
• 安装过程很详细，按照流程就可以按照成功。

4.安装caffe

（1）将终端cd到要安装caffe的位置。
（2）从github上获取caffe：

git clone https://github.com/BVLC/caffe.git

注意：若没有安装Git，需要先安装Git：

sudo apt-get install git

（3）因为make指令只能make Makefile.config文件，而Makefile.config.example是caffe给出的makefile例子，因此，首先将Makefile.config.example的内容复制到Makefile.config：

sudo cp Makefile.config.example Makefile.config

（4）打开并修改配置文件：

sudo gedit Makefile.config #打开Makefile.config文件

• 自己按照改了一下，里面有写需要注意

问题：

第一次编译：出错

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler
sudo apt-get install --no-install-recommends libboost-all-dev

AR -o .build_release/lib/libcaffe.a
LD -o .build_release/lib/libcaffe.so.1.0.0
/usr/bin/ld: 找不到 -lhdf5_hl

/usr/bin/ld: 找不到 -lcudnn
collect2: error: ld returned 1 exit status
Makefile:572: recipe for target '.build_release/lib/libcaffe.so.1.0.0' failed
make: *** [.build_release/lib/libcaffe.so.1.0.0] Error 1

- hdf5的问题，通过修改Makefile.config文件

在文件里面添加文本由于hdf5库目录更改，所以需要单独添加：
#INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/
#LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include /usr/lib/x86_64-linux-gnu/hdf5/serial/include
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu/hdf5/serial

- 然后再次编译有一个问题：

dsp@dsp:~/caffe$ make all -j16
LD -o .build_release/lib/libcaffe.so.1.0.0
/usr/bin/ld: 找不到 -lcudnn
collect2: error: ld returned 1 exit status

make: *** [.build_release/lib/libcaffe.so.1.0.0] Error 1

• i found that in the path "/usr/local/cuda/lib64/" don't have the file liblcudnn.so

该问题还在有待解决。

- 这个问题其实挺简单的：后面自己想清楚了：就是cudnn的链接问题，重新拷贝cudnn文件；然后链接了一遍，后面就不报这个错了

- 继续编译错误：

//home/dsp/anaconda2/lib/libpng16.so.16：对‘inflateValidate@ZLIB_1.2.9’未定义的引用/
/homecollect2: error: ld returned 1 exit status

- 然后我添加链接：sudo ln -s /home/username/anaconda2/lib/libpng16.so.16 libpng16.so.16 （方法不行）报另外的错：

- 最后非常感谢：Caffe 编译错误记录：http://blog.csdn.net/ruotianxia/article/details/78437464 

• 里面的几个错误有代表性，按照下面的方法就没有报这个错了

在 Makefile.config 中，加入下一句
LINKFLAGS := -Wl,-rpath,$(HOME)/anaconda2/lib

- 然后执行：make all  报错：

dsp@dsp:~/caffe$ make all -j16
make: Nothing to be done for 'all'

• 解决方法很简单：

•  make: Nothing to be done for `all' 解决方法
  1.这句提示是说明你已经编译好了，而且没有对代码进行任何改动。
  若想重新编译，可以先删除以前编译产生的目标文件：
  
      make clean 
  
      make 

5. 黎明的曙光

• 按照如下编译顺序

make all -j16
make runtest -j16
make pycaffe -j16
make matcaffe -j16

- 其中make all 和make runtest时间比较长；make pycaffe 很顺利

• 通过conda下安装protobuf即可

• python caffe报错：No module named google.protobuf.internal
  
  我装的是anaconda2, 解决方法是在其中安装protobuf最新版本
  
  conda install protobuf

6. MNIST数据集测试

配置caffe完成后，我们可以利用MNIST数据集对caffe进行测试，过程如下：
1.将终端定位到Caffe根目录

cd ~/caffe

2.下载MNIST数据库并解压缩

./data/mnist/get_mnist.sh

3.将其转换成Lmdb数据库格式

./examples/mnist/create_mnist.sh

4.训练网络

 ./examples/mnist/train_lenet.sh

训练的时候可以看到损失与精度数值，如下图：

- make matcaffe 有gcc版本问题

dsp@dsp:~/caffe$ make matcaffe -j16
MEX matlab/+caffe/private/caffe_.cpp
使用 'g++' 编译。
警告: 您使用的 gcc 版本为 '5.4.0'。不支持该版本的 gcc。MEX 当前支持的版本为 '4.9.x'。有关当前支持的编译器列表，请参阅: http://www.mathworks.com/support/compilers/current_release。
MEX 已成功完成。

• 解决办法是：
  
   在Makefile里面，大约第410行那一句话
  
  CXXFLAGS += -MMD -MP
  
  下面添加CXXFLAGS += -std=c++11，
  
  最后是这样 CXXFLAGS += -MMD -MP CXXFLAGS += -std=c++11
  
  然后在caffe根目录下make clean,make all

- 执行 make mattest的时候，报错：

.......

出错 caffe.set_mode_cpu (line 5)
caffe_('set_mode_cpu');

出错 caffe.run_tests (line 6)
caffe.set_mode_cpu();

- 参考：Caffe中使用MATLAB接口

•  最后设置调用caffe/python的路径，可以在任意路径终端下导入caffe
• 经过差不多两天的时间，安装了很多东西，情形庆幸没有重装系统，具体的内容如下：

cuda: /usr/local/
opencv_3.1: /usr/local/
anaconda2,caffe: /home/dsp/

python系统默认：2.7
anaconda：2.7 ；虚拟环境下tensorflow_py3.5

matlab2017a: /home/dsp/bin/matlab
caffe: /home/dsp/caffe

使用方法：
------
matlab2017a： 终端输入： matlab即可，界面有问题，待解决

------
默认终端python:
dsp@dsp:~$ python
Python 2.7.14 |Anaconda, Inc.| (default, Oct 16 2017, 17:29:19) 
[GCC 7.2.0] on linux2

------
终端输入：spyder
python为：anaconda自带的python2.7

------
tensorflow1.4 + python3.5使用：
dsp@dsp:~$ source activate tensorflow_py3.5
(tensorflow_py3.5) dsp@dsp:~$ spyder

注： 1. 需要不同的python环境，需要自己创建虚拟环境
     2. 安装依赖项时注意，安装的位置
     3. 也可以通过：(tensorflow_py3.5) dsp@dsp:~$ anaconda-navigator 来安装和启动spyder


------
pycharm 使用：

1. 解压安装包可直接使用
2. 运行：(tensorflow_py3.5) dsp@dsp:~$ sh ./pycharm/bin/pycharm.sh ；只要路径对即可
3. 设置解释器为：python2.7 或者tensorflow_py3.5

------
caffe 使用：

1. 使用anaconda自带的python2.7即可
2. 添加caffe的路径，再使用
3. 本机可以在任意路径终端下：输入：python； 然后：import caffe
