本来实在windows 10上尝试安装caffe,装了一天没装上,放弃; 改在windows上装ubuntu的双系统,装了一个下午,不小心windows的系统盘被锁死了,也不会unlock?只好含泪卸掉了windows10,只装ubuntu 15.10。过程真是让人揩一把辛酸泪。。。不过又在ubuntu中用错了一个命令,系统崩溃,重新安装win8.1 + ubuntu 14.04, 成功,继续安装caffe。。。

安装:

ubuntu 14  .04,

 

1. 安装开发所需依赖包:

sudo apt-get install build-essential  # basic requirement  
sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libboost-all-dev libhdf5-serial-dev libgflags-dev libgoogle-glog-dev liblmdb-dev protobuf-compiler #required by caffe

 

2. 安装CUDA 7.5:

根据Nvidia官方文档http://developer.download.nvidia.com/compute/cuda/7.5/Prod/docs/sidebar/CUDA_Installation_Guide_Linux.pdf一步一步安装

  1) 确定GPU支持CUDA

lspci | grep -i nvidia

  结果显示:

  Ubuntu 14.04上安装caffe

http://developer.nvidia.com/cuda-gpus去验证,发现支持CUDA

  2) 确定linux版本支持CUDA:

uname -m && cat /etc/*release

  结果显示:

  Ubuntu 14.04上安装caffe

  3) 确定系统已经安装了gcc:

gcc --version

  结果显示:

  Ubuntu 14.04上安装caffe

  4) 确定系统已经安装了正确的Kernel Headers和开发包:

  查看系统正在运行的kernel版本:

uname -r

  结果:4.2.0-35-generic,这个是必须安装的kernel headers和开发包的版本

  安装对应的kernels header和开发包:

sudo apt-get install linux-headers-$(uname -r)

  5) 安装CUDA:下载对应版本的cuda,从https://developer.nvidia.com/cuda-downloads,下载deb(network)版

  首先进行md5校验:

md5sum cuda-repo-ubuntu1404_7.5-18_amd64.deb

  对比相同,然后使用deb文件进行安装:

sudo dpkg -i cuda-repo-ubuntu1404_7.5-18_amd64.deb 
sudo apt-get update
sudo apt-get install cuda

   重启,完成cuda安装

 

3. 安装cuDNN

下载从https://developer.nvidia.com/rdp/cudnn-download cuDNN,版本为cudnn-7.0-linux-x64-v3.0-prod.tgz

tar -zxvf cudnn-7.0-linux-x64-v3.0-prod.tgz 
cd cuda
sudo cp lib64/* /usr/local/cuda/lib64/
sudo cp include/cudnn.h /usr/local/cuda/include/ 

更新软链接?不懂,照做

cd /usr/local/cuda/lib64
sudo rm -rf libcudnn.so libcudnn.so.7.0
sudo ln -s libcudnn.so.7.0.64 libcudnn.so.7.0
sudo ln -s libcudnn.so.7.0 libcudnn.so


4. 设置环境变量:

在/etc/profile中添加CUDA 环境变量

sudo gedit /etc/profile,在打开的文件中加入如下两句话

export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

保存后,使环境变量立即生效:source /etc/profile

 

5. 安装cuda samples

进入/usr/local/cuda/samples,执行下面的命令来build samples

sudo make all -j4

全部编译完成后,进入 samples/bin/x86_64/linux/release, 运行deviceQuery: ./deviceQuery

如果出现显卡信息,则驱动及显卡安装成功,结果如下:

Ubuntu 14.04上安装caffe

安装成功!

 

6. 安装Intel MKL,openBlas 或Atlas:

我选择的是Atlas,为caffe默认使用的,不要额外配置,安装命令

sudo apt-get install libatlas-base-dev

 

7. 安装opencv:

首先安装必须的包

sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

从opencv官网下载最新版本opencv,opencv-3.1.0.zip

解压unzip opencv-3.1.0.zip

编译

cd  opencv-3.1.0
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make
sudo make install

 测试是否安装成功:

 mkdir ~/opencv-workshop
cd ~/opencv-workshop/
gedit DisplayImage.cpp
gedit CMakeLists.txt
cmake .
make

其中 Display.cpp的代码为

#include <stdio.h>
#include <opencv2/opencv.hpp>
using namespace cv;

int main(int argc, char** argv)
{
    Mat image;
    image = imread(argv[1], 1);
    if (!image.data)
    {
        printf("No image data\n");
        return -1;
    }
    namedWindow("display", WINDOW_AUTOSIZE);
    imshow("display", image);
    waitKey(0);
    return 0;
}

其中 CMakeList.txt的内容是

cmake_minimum_required(VERSION 2.8)
project(DisplayImage)
find_package(OpenCV REQUIRED)
add_executable(DisplayImage DisplayImage.cpp)
target_link_libraries(DisplayImage ${OpenCV_LIBS})

脚本运行后,运行可执行文件,看是否能正确显示图片,能,则成功

./DisplayImage ~/图片/2016-04-13\ 21\:35\:01屏幕截图.png 

 

8. 安装caffe所需要的Python环境Anaconda:

按caffe推荐,python环境使用Anaconda,去官网下载安装包http://conda.pydata.org/miniconda.html,

 下载Anaconda2-4.0.0-Linux-x86_64.sh,切换到文件所在路径,执行

bash Anaconda2-4.0.0-Linux-x86_64.sh

按照提示进行安装。

安装好后,在/etc/ld.so.conf中添加一下路径:/home/wm/anaconda2/lib

在~/.bashrc最后添加下面一句:

export LD_LIBRARY_PATH="/home/wm/anaconda2/lib:$LD_LIBRARY_PATH"

 

9. 安装python依赖库

下载caffe源码,解压后进入caffe-master下的python目录,

(首先要安装python-pip

sudo apt-get install python-pip

)执行如下命令

 for req in $(cat requirements.txt); do pip install $req; done

 

10. 编译Caffe

进入caffe-master目录,复制一份Makefile.config.examples

cp Makefile.config.example Makefile.config 

修改Makefile.config中的路径,只需要将默认的Python路径注释掉,去掉对Anaconda路径的注释,并且开启CuDNN和Opencv3的支持即可,修改好的如下:

## 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).

        -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)!
# BLAS_INCLUDE := /path/to/your/blas

#        /usr/lib/python2.7/dist-packages/numpy/core/include
# Anaconda Python distribution is quite popular. Include path:
# Verify anaconda location, sometimes it\'s in root.
ANACONDA_HOME := $(HOME)/anaconda
PYTHON_INCLUDE := $(ANACONDA_HOME)/include \
         $(ANACONDA_HOME)/include/python2.7 \
         $(ANACONDA_HOME)/lib/python2.7/site-packages/numpy/core/include \

# Uncomment to use Python 3 (default is Python 2)

# PYTHON_INCLUDE := /usr/include/python3.5m \
#                 /usr/lib/python3.5/dist-packages/numpy/core/include

# PYTHON_LIB := /usr/lib
PYTHON_LIB := $(ANACONDA_HOME)/lib

# Homebrew installs numpy in a non standard path (keg only)
# PYTHON_INCLUDE += $(dir $(shell python -c \'import numpy.core; print(numpy.core.__file__)\'))/include

Q ?= @

保存退出,编译

make all
make test
make runtest

没有报错,成功。

 

11. 使用MNIST数据集进行测试

1) 数据预处理:

sh data/mnist/get_mnist.sh 

2) 重建lmdb/leveldb文件,命令

sh examples/mnist/create_mnist.sh 

3) 训练mnist,命令

sh examples/mnist/train_lenet.sh

这是可以看到caffe的训练过程,至此caffe配置已成功:

Ubuntu 14.04上安装caffe

接下来会学习caffe的使用。。。 加油
