caffe安装教程（2）/caffe安装与编译

在上一节，我们安装好了所有caffe可能用到的软件，我这里再列举一下：
- NVIDIA驱动367.57
- CUDA8.0
- Cudnn v5.1
- MKL（这里我提一句，最后BLAS可以不用MKL，用openblas或者atlas都可以）
- MATLAB2014a
- Anaconda(Python 2.7版)
- OpenCV 2.4.13

接下来，我们进入caffe的安装与编译环节。

1. 在安装caffe前，我们先来安装一些依赖

   sudo apt-get install -y libprotobuf-dev libleveldb-dev libsnappy-dev libhdf5-serial-dev protobuf-compiler;
   
   sudo apt-get install -y libatlas-base-dev;
   
   sudo apt-get install -y --no-install-recommends libboost-all-dev;
   
   sudo apt-get install -y libgflags-dev libgoogle-glog-dev liblmdb-dev;
   
   sudo apt-get install -y python-pip python-dev python-numpy python-scipy;
   
   sudo apt-get install -y libopencv-dev;

2. 安装依赖后，我们再来修改Make.config文件,如下：

   
   ## Refer to http://caffe.berkeleyvision.org/installation.html
   
   
   # Contributions simplifying and improving our build system are welcome!
   
   
   
   # cuDNN acceleration switch (uncomment to build with cuDNN).
   
   USE_CUDNN := 1
   
   
   # CPU-only switch (uncomment to build without GPU support).
   
   
   # CPU_ONLY := 1
   
   
   
   # uncomment to disable IO dependencies and corresponding data layers
   
   USE_OPENCV := 0
   USE_LEVELDB := 0
   USE_LMDB := 0
   
   
   # uncomment to allow MDB_NOLOCK when reading LMDB files (only if necessary)
   
   
   #   You should not set this flag if you will be reading LMDBs with any
   
   
   #   possibility of simultaneous read and write
   
   
   # ALLOW_LMDB_NOLOCK := 1
   
   
   
   # Uncomment if you're using OpenCV 3
   
   
   # OPENCV_VERSION := 3
   
   
   
   # To customize your choice of compiler, uncomment and set the following.
   
   
   # N.B. the default for Linux is g++ and the default for OSX is clang++
   
   
   # CUSTOM_CXX := g++
   
   
   
   # CUDA directory contains bin/ and lib/ directories that we need.
   
   CUDA_DIR := /usr/local/cuda
   
   # On Ubuntu 14.04, if cuda tools are installed via
   
   
   # "sudo apt-get install nvidia-cuda-toolkit" then use this instead:
   
   
   # CUDA_DIR := /usr
   
   
   
   # CUDA architecture setting: going with all of them.
   
   
   # For CUDA < 6.0, comment the *_50 lines for compatibility.
   
   CUDA_ARCH := -gencode arch=compute_20,code=sm_20 \
       -gencode arch=compute_20,code=sm_21 \
       -gencode arch=compute_30,code=sm_30 \
       -gencode arch=compute_35,code=sm_35 \
       -gencode arch=compute_50,code=sm_50 \
       -gencode arch=compute_50,code=compute_50
   
   
   # BLAS choice:
   
   
   # atlas for ATLAS (default)
   
   
   # mkl for MKL
   
   
   # open for OpenBlas
   
   BLAS := atlas
   
   # Custom (MKL/ATLAS/OpenBLAS) include and lib directories.
   
   
   # Leave commented to accept the defaults for your choice of BLAS
   
   
   # (which should work)!

   ANACONDA_HOME := $(HOME)/anaconda2
   PYTHON_INCLUDE := $(ANACONDA_HOME)/include \
       $(ANACONDA_HOME)/include/python2.7 \
       $(ANACONDA_HOME)/lib/python2.7/site-packages/numpy/core/include \

   # PYTHON_LIB += $(shell brew --prefix numpy)/lib
   
   
   
   # Uncomment to support layers written in Python (will link against Python libs)

   Q ?= @

3. 最后我们来编译caffe和python,matlab与caffe的接口，并测试。
   编译caffe：

   sudo make all -j16;
   sudo make test -j16;
   sudo make runtest -j16;

   编译pycaffe和matcaffe:

   sudo make pycaffe -j16;
   sudo make matcaffe -j16;
   sudo make pytest -j16;
   sudo make mattest -j16;

   如果以上命令全部成功执行，我们就完全安装好了caffe。

如果安装过程中出现了错误，那该怎么处理呢？
我在这里就列举一下，当初我安装caffe与编译pycaffe和matcaffe时，出现的错误。

     make: *** [.build_release/src/caffe/layers/softmax_loss_layer.o] Error 1
     

     解决方法：
     这是由于没有安装boost导致的错误。要想使用caffe，安装的boost版本必须高于1.55。所以在命令行执行以下即可。
     sudo apt-get install libboost1.55-*

  3. libcudart 错误
     当编译caffe时，出现有关libcudart错误时，往往是cuda的路径没有设置对。这个时候我们要修改Makefile.config文件和ld.conf.d文件夹下的cuda.conf文件（如果该文件夹下没有该文件则要新建一个）

     
     # 修改makefile文件，添加/usr/local/cuda/include和/usr/local/cuda/lib64
     
     INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/local/cuda/include
     LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/local/cuda/lib64
     
     
     #修改目录/etc/ld.so.conf.d下的cuda.conf文件，将/usr/local/cuda/include和/usr/local/cuda/lib64添加进去
     
     cd /etc/ld.so.conf.d
     sudo vim cuda.conf
     
     #insert two paths above
     

至此caffe应该可以顺利的编译完毕。

接下来我们看看编译pycaffe时会出现的问题

1. 安装一些python依赖
   进入caffe目录下的python文件夹然后执行下列操作：
   for req in $(cat requirements.txt); do pip install $req; done
   这样就安装了一些python的依赖

2. skimage.io错误
   如果出现该错误，说明有一些依赖没有正确的安装，执行以下程序：

   sudo apt-get install python-numpy python-scipy python-matplotlib python-sklearn python-skimage python-h5py python-protobuf python-leveldb python-networkx python-nose python-pandas python-gflags Cython ipython;#主要是看看python-skimage有没有安装

3. ImportError: No module named google.protobuf.internal
   这是由于没有安装protobuf导致的。
   pip install protobuf就ok了

4. import caffe时出现了问题：Intel MKL FATAL ERROR: Cannot load libmkl_avx2.so or libmkl_def.so
   这个跟anaconda有关，一般情况下，我们使用Linux自带的python就可以了，没必要整anaconda。如果非要使用anaconda的话。使用一下办法解决这个问题。
   conda install nomkl numpy scipy scikit-learn numexprconda remove mkl mkl-service
   安装一些包，移除一些包就可以了。

---

最后就是编译matcaffe出现的问题了。
我最近重装了一次标准版的caffe，编译matcaffe时只出现了一个问题。就是要用-std=c++11的gcc去编译matcaffe。这个很好解决，只需要在Makefile文件中查找CXXFLAG，然后在一个什么mp的表达式下面加上一句话就行了。

---

• 编译完之后的路径设置问题。
  我们编译好了caffe和pycaffe以及matcaffe后，需要将caffe和pycaffe的库文件路径添加到系统路径中，这样我们才能正常的使用caffe。
  涉及到的文件有：

  • ~/.bashrc
  • /etc/profile
  • /etc/ld.conf.d 目录下的 ~.conf文件

• 编译完之后的测试问题

  • mnist测试caffe命令行版本

以上是编译普通caffe 的方法，这一套流程我已经走过很多遍了，应该没有问题。
这里需要注意的是，当你需要编译ssd 版的caffe或者别的研究团队改过的caffe时，最好使用cmake 的方法编译，具体内容以后有时间我会补充上来的。
