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

• 上午把tensorflow安裝好了，下午和晚上裝caffe的確很費勁。
• 默認CUDA,cuDNN可以用了
• caffe官方安裝教程
• 有些安裝順序自己也不清楚，簡直就是碰運氣

1. 安裝之前依賴項

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

安裝matlab見后面：

為什么需要安裝Matlab？
caffe有Matlab的接口，因此如果需要使用Matlab調用caffe，進行編程，就需要安裝Matlab。如果你覺得使用C或Python編程比較難，就請安裝Matlab。當然如果不需要，並且后面不會編譯caffe生成Matlab的接口，就不需要安裝Matlab了。這個純粹根據個人需求來定。


為什么需要安裝OpenCV？
caffe是用來做深度學習的，深度學習的一大應用對象就是圖像和視頻。而OpenCV是目前最火的開源計算機視覺庫，非常多的項目多用到了OpenCV，當然caffe也依賴OpenCV。所以，需要安裝OpenCV，否則無法使用caffe哦

OpenCV的版本和cuda的版本最好匹配。這樣子安排的目的是為了減少錯誤出現的概率

 

2.OpeCV安裝

從官網(http://opencv.org/downloads.html)下載Opencv,並將其解壓到你要安裝的位置，假設解壓到了/home/opencv。 安裝前准備，創建編譯文件夾：

cd ~/opencv
mkdir build
cd build

配置：

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

編譯：

make -j8 #-j8表示並行計算，根據自己電腦的配置進行設置，配置比較低的電腦可以將數字改小或不使用，直接輸make。

以上只是將opencv編譯成功，還沒將opencv安裝，需要運行下面指令進行安裝：

sudo make install

問題：由於CUDA 8.0不支持OpenCV的 GraphCut 算法，可能出現以下錯誤：

 

/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務....
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務....
[ 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

 

進入opencv-3.1.0/modules/cudalegacy/src/目錄，修改graphcuts.cpp文件，將：

#include "precomp.hpp"

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

改為

#include "precomp.hpp"

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

然后make編譯就可以了

- 編譯和安裝完成

 

裝BLAS

這里可以選擇（ATLAS，MKL或者OpenBLAS）：不知道這個，下載有問題，所以就沒有搞這個，但是makefile.config文件里面有配置

MKL首先下載並安裝英特爾® 數學內核庫 Linux* 版MKL(Intel(R) Parallel Studio XE Cluster Edition for Linux 2016)，下載鏈接是：https://software.intel.com/en-us/qualify-for-free-software/student， 使用學生身份（郵件 + 學校）下載Student版，填好各種信息，可以直接下載，同時會給你一個郵件告知序列號。

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

sudo apt-get install libatlas-base-dev 

 3.MATLAB2017a安裝

• utuntu2017a安裝:http://blog.csdn.net/u011713358/article/details/69659265
• 安裝過程很詳細，按照流程就可以按照成功。

4.安裝caffe

（1）將終端cd到要安裝caffe的位置。
（2）從github上獲取caffe：

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

注意：若沒有安裝Git，需要先安裝Git：

sudo apt-get install git

（3）因為make指令只能make Makefile.config文件，而Makefile.config.example是caffe給出的makefile例子，因此，首先將Makefile.config.example的內容復制到Makefile.config：

sudo cp Makefile.config.example Makefile.config

（4）打開並修改配置文件：

sudo gedit Makefile.config #打開Makefile.config文件

• 自己按照改了一下，里面有寫需要注意

問題：

第一次編譯：出錯

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 -lhdf5
/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的問題，通過修改Makefile.config文件

在文件里面添加文本由於hdf5庫目錄更改，所以需要單獨添加：
#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

- 然后再次編譯有一個問題：

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

該問題還在有待解決。

- 這個問題其實挺簡單的：后面自己想清楚了：就是cudnn的鏈接問題，重新拷貝cudnn文件；然后鏈接了一遍，后面就不報這個錯了

- 繼續編譯錯誤：

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

collect2: error: ld returned 1 exit status

- 然后我添加鏈接：sudo ln -s /home/username/anaconda2/lib/libpng16.so.16 libpng16.so.16 （方法不行）報另外的錯：

- 最后非常感謝：Caffe 編譯錯誤記錄：http://blog.csdn.net/ruotianxia/article/details/78437464 

• 里面的幾個錯誤有代表性，按照下面的方法就沒有報這個錯了

 

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

- 然后執行：make all  報錯：

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

• 解決方法很簡單：

•  make: Nothing to be done for `all' 解決方法
  1.這句提示是說明你已經編譯好了，而且沒有對代碼進行任何改動。
  若想重新編譯，可以先刪除以前編譯產生的目標文件：
  
      make clean 
  
      make 

 

5. 黎明的曙光

• 按照如下編譯順序

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

- 其中make all 和make runtest時間比較長；make pycaffe 很順利

• 通過conda下安裝protobuf即可

• python caffe報錯：No module named google.protobuf.internal
  
  我裝的是anaconda2, 解決方法是在其中安裝protobuf最新版本
  
  conda install protobuf

6. MNIST數據集測試

配置caffe完成后，我們可以利用MNIST數據集對caffe進行測試，過程如下：
1.將終端定位到Caffe根目錄

cd ~/caffe

2.下載MNIST數據庫並解壓縮

./data/mnist/get_mnist.sh

3.將其轉換成Lmdb數據庫格式

./examples/mnist/create_mnist.sh

4.訓練網絡

 ./examples/mnist/train_lenet.sh

訓練的時候可以看到損失與精度數值，如下圖：

- make matcaffe 有gcc版本問題

dsp@dsp:~/caffe$ make matcaffe -j16
MEX matlab/+caffe/private/caffe_.cpp
使用 'g++' 編譯。
警告: 您使用的 gcc 版本為 '5.4.0'。不支持該版本的 gcc。MEX 當前支持的版本為 '4.9.x'。有關當前支持的編譯器列表，請參閱: http://www.mathworks.com/support/compilers/current_release。
MEX 已成功完成。

• 解決辦法是：
  
   在Makefile里面，大約第410行那一句話
  
  CXXFLAGS += -MMD -MP
  
  下面添加CXXFLAGS += -std=c++11，
  
  最后是這樣 CXXFLAGS += -MMD -MP CXXFLAGS += -std=c++11
  
  然后在caffe根目錄下make clean,make all

- 執行 make mattest的時候，報錯：

.......

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

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

- 參考：Caffe中使用MATLAB接口

•  最后設置調用caffe/python的路徑，可以在任意路徑終端下導入caffe
• 經過差不多兩天的時間，安裝了很多東西，情形慶幸沒有重裝系統，具體的內容如下：

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

python系統默認：2.7
anaconda：2.7 ；虛擬環境下tensorflow_py3.5

終端輸入：spyder
python為：anaconda自帶的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環境，需要自己創建虛擬環境
     2. 安裝依賴項時注意，安裝的位置
     3. 也可以通過：(tensorflow_py3.5) dsp@dsp:~$ anaconda-navigator 來安裝和啟動spyder


------
pycharm 使用：

1. 解壓安裝包可直接使用
2. 運行：(tensorflow_py3.5) dsp@dsp:~$ sh ./pycharm/bin/pycharm.sh ；只要路徑對即可
3. 設置解釋器為：python2.7 或者tensorflow_py3.5

------
caffe 使用：

1. 使用anaconda自帶的python2.7即可
2. 添加caffe的路徑，再使用
3. 本機可以在任意路徑終端下：輸入：python； 然后：import caffe
