1. CUDA的安装

前面已经装过了，可以查看一下

$ cat /usr/local/cuda/version.txt
CUDA Version 8.0.44

确认是否安装成功：

$ cd ~/NVIDIA_CUDA-8.0_Samples/bin/x86_64/linux/release/
$ ./deviceQuery

如果显示显卡信息，说明安装成功。

2. 安装cuDNN

前面已经安装过了。

3. 安装BLAS（基本线性代数子库）

Caffe支持的有三种：MKL，AtLas，OpenBlas。
OpenBlas是完全免费的，所以这里就安装它了：

$ sudo apt-get install openblas-dev

错误：

E: 无法定位软件包 openblas-dev

解决：

$ apt-cache search openblas
libblas-test - Basic Linear Algebra Subroutines 3, testing programs
libopenblas-base - Optimized BLAS (linear algebra) library (shared library)
libopenblas-dev - Optimized BLAS (linear algebra) library (development files)
$ sudo apt-get install libopenblas-dev

注意：安装后要修改Caffe中的Makefile.config文件的BLAS选项为open，才能使其生效。

4. 安装OpenCV

前面已经安装过了，现在查看是否安装成功：

 $ python
Python 2.7.14 |Anaconda, Inc.| (default, Oct 16 2017, 17:29:19) 
[GCC 7.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2.__version__
'3.2.0'
>>>

5. 安装caffe的python环境（Anaconda）

前面已经安装过了，在终端输入“python”, python 的版本信息,但是后面带了 anaconda 的标识,这就说明Anaconda 安装成功了

$ python
Python 2.7.14 |Anaconda, Inc.| (default, Oct 16 2017, 17:29:19) 
[GCC 7.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

6. 下载caffe源码包

cd ~/download
$ git clone https://github.com/BVLC/caffe.git
$ cd ~/download
$ cp -r ./caffe ~/

7.安装caffe的python依赖库

cd ~/caffe/python
$ for req in $(cat requirements.txt); do pip install $req; done

如果提示权限不够，换root用户执行。

8. 编译caffe

8.1 配置文件修改

$ cd ~/caffe
$ cp Makefile.config.example Makefile.config

8.1.1Makefile.config文件修改如下：

（1）第21行

 # OPENCV_VERSION := 3

改为：

 OPENCV_VERSION := 3

（2）第69行

PYTHON_INCLUDE := /usr/include/python2.7 \
                  /usr/lib/python2.7/dist-packages/numpy/core/include

后面添加：

 /home/fc/anaconda2/lib/python2.7/site-packages/numpy/core/include

（3）第97行将# Whatever else you find you need goes here.下面的

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib

修改为:

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/hdf5/serial

8.1.2修改 makefile 文件

打开 Makefile 文件,在 415 行,将:

NVCCFLAGS +=-ccbin=$(CXX) -Xcompiler-fPIC $(COMMON_FLAGS)

替换为:

NVCCFLAGS += -D_FORCE_INLINES -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS)

8.2 编译

$ make all -j4
$ make test -j4
$ make runtest -j4

9. pycaffe配置

9.1 安装依赖

$ 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 ipython cython
$ sudo apt-get install protobuf-c-compiler protobuf-compiler

9.2 依赖库编译

$ cd ~/caffe
$ make pycaffe

10 配置环境变量,以便 python 调用

$sudo vim ~/.bashrc

加入

export PYTHONPATH=/home/fc/caffe/python:$PYTHONPATH

$ source ~/.bashrc

11.测试

$ python
Python 2.7.14 |Anaconda, Inc.| (default, Oct 16 2017, 17:29:19) 
[GCC 7.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import caffe
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/fc/caffe/python/caffe/__init__.py", line 1, in <module>
    from .pycaffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, RMSPropSolver, AdaDeltaSolver, AdamSolver, NCCL, Timer
  File "/home/fc/caffe/python/caffe/pycaffe.py", line 15, in <module>
    import caffe.io
  File "/home/fc/caffe/python/caffe/io.py", line 8, in <module>
    from caffe.proto import caffe_pb2
  File "/home/fc/caffe/python/caffe/proto/caffe_pb2.py", line 6, in <module>
    from google.protobuf.internal import enum_type_wrapper
ImportError: No module named google.protobuf.internal
>>>

问题：

ImportError: No module named google.protobuf.internal

解决：这说明没有添加google.protobuf.的位置

a.临时性添加

$ python
Python 2.7.14 |Anaconda, Inc.| (default, Oct 16 2017, 17:29:19) 
[GCC 7.2.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path.append('/usr/lib/python2.7/dist-packages/')
>>> import caffe
>>>

这样有个问题是，当关闭shell后，就会失效

b. 永久性添加

shell 下，

$ cd /usr/lib/python2.7/dist-packages

然后建立一个.pth的文件，例如我们建立一个mypth.pth

$ sudo echo mypth.pth

然后我们打开这个文件进行编辑

$ sudo vim mypth.pth

然后就会看到我们建立的文件打开了，在文件里添加我们要添加的模块路径，例如我的是 /home/fc/caffe/python/，保存退出

另外：这个方法可以试试

$ sudo chmod 777 -R ~/anaconda2
$ pip install protobuf
