Caffe+Ubuntu14.04+CUDA7.5安装笔记

前端之家收集整理的这篇文章主要介绍了Caffe+Ubuntu14.04+CUDA7.5安装笔记前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

ubuntu 14.04安装



cuda7.5安装

  1. cuda7.5下载:地址https://developer.nvidia.com/cuda-downloads
    文件: cuda_7.5.18_linux.run
  2. 登录界面前按Ctrl+Alt+F1进入命令提示符 【禁用nouveau驱动】
  3. 执行命令: sudo vi /etc/modprobe.d/blacklist-nouveau.conf
  4. 输入以下内容

    blacklist nouveau
    options nouveau modset=0

    最后保存退出(:wq)

  5. 执行命令: sudo update-initramfs -u
    再执行命令: lspci | grep nouveau 查看是否有内容
    如果没有内容 ,说明禁用成功,如果有内容,就重启一下再查看
    sudo reboot
    重启后,进入登录界面的时候,不要登录进入桌面,直接按Ctrl+Alt+F1进入命令提示符。

  6. 重启后,登录界面时直接按Ctrl+Alt+F1进入命令提示

  7. 安装依赖项:
    sudo service lightdm stop
    sudo apt-get install g++
    sudo apt-get installGit
    sudo apt-get install freeglut3-dev

  8. 假设cuda_7.5.18_linux.run位于 ~ 目录,切换到~目录: cd ~

  9. 执行命令: sudo sh cude_7.5.18_linux.run

  10. 安装的时候,要让你先看一堆文字(EULA),我们直接不停的按空格键到100%,然后输入一堆accept,yes,yes或回车进行安装。安装完成后,重启,然后用ls查看一下:
    ls /dev/nvidia*
    会看到/dev目录下生成多个nvidia开头文件(夹)
    或者输入命令: sudo nvcc –version 会显示类似以下信息

    dl@dl-Z170X-Gaming-3:~$ nvcc --version nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2015 NVIDIA Corporation Built on Tue_Aug_11_14:2732_CDT_2015 Cuda compilation tools,release 7.5,V7.5.17
  11. 配置环境变量
    执行命令: sudo vi /etc/profile
    文件底部添加以下内容

       
       
    • 1
    • 2
    • 1
    • 2
    export PATH=/usr/local/cuda-7.5/bin:$PATH export LD_LIBRARY_PATH=/usr/local/cuda-7.5/lib64:$LD_LIBRARY_PATH//注意这里的问题lib64而不是lib
  12. 编译samples
    安装成功后在~目录下可以看到一个NVIDIA_CUDA-7.5_Samples文件夹,切换到目录
    输入sudo make, 大概等个十多分钟后就会把全部的samples编译完毕。生成的可执行文件位于
    NVIDIA_CUDA-7.5_Samples/bin/x86_64/Linux/release 目录下
    比如运行 ./nbody可以看到以下demo


cuda安装过程中遇到的问题

Q1

  1. 在执行命令: sudo apt-get install g++ 时出现以下错误
    g++ : Depends: g++-4.8 (>= 4.8.2-5~) but it is not going to be installed
  2. 是因为ubuntu 14.04的源过旧或不可访问导致,可以通过更新源解决

  3. 首先,备份原始源文件source.list
    sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

  4. 然后
    sudo gedit /etc/apt/source.list
    文件尾部添加以下内容

    安装caffe

    1. 下载caffe:执行命令: sudo git clonehttps://github.com/BVLC/caffe.git
    2. 安装依赖项:

      sudo apt-get install libatlas-base-dev
      sudo apt-get install libprotobuf-dev
      sudo apt-get install libleveldb-dev
      sudo apt-get install libsnappy-dev
      sudo apt-get install libopencv-dev
      sudo apt-get install libboost-all-dev
      sudo apt-get install libhdf5-serial-dev
      sudo apt-get install libgflags-dev
      sudo apt-get install libgoogle-glog-dev
      sudo apt-get install liblmdb-dev
      sudo apt-get install protobuf-compiler

    3. 编译caffe
      cd ~/caffe
      sudo cp Makefile.config.example Makefile.config
      make all

    4. 配置运行环境
      sudo vi /etc/ld.so.conf.d/caffe.conf
      添加内容
      /usr/local/cuda/lib64

    5. 更新配置
      sudo ldconfig
    6. caffe测试,执行以下命令:
      cd ~/caffe
      sudo sh data/mnist/get_mnist.sh
      sudo sh examples/mnist/create_mnist.sh
      最后测试:
      sudo sh examples/mnist/train_lenet.sh

    运行结果如下:


    其他依赖项

    我们查看caffe目录下 Makefile.config 内容如下:

    opencv3.0安装

    1. github上有人写好完整的运行脚本自动下载OpenCV,编译,安装,配置等

    2. Caffe + Ubuntu 15.04 + CUDA 7.5 新手安装配置指南作者 Xin-Yu Ou(欧新宇) 可以到他的网盘中下载
      PS:为了方便大家使用,我提供一个百度云盘,用于分享部分安装过程中需要用到的软件包和链接地址(所有软件包仅供学术交流使用,请大家尽量去官网下载。)。百度云盘链接:http://pan.baidu.com/s/1qX1uFHa密码:wysa

    3. 在Install-OpenCV-master文件夹中包含安装各个版本opencv脚本

    4. 切换到目录执行:
      sudo sh Ubuntu/dependencies.sh
      安装依赖项

    5. 执行opencv3.0安装脚本
      sudo sh Ubuntu/3.0/opencv3_0_0.sh
      等待安装完成即可

    6. 修改Makefile.config

    11. (可选)opencv3.1已经发布,如果要安装最新的opencv3.1,我们可以先执行
      sudo sh get_latest_version_download_file.sh
      获取最新的地址,然后更新opencv3_0_0.sh中的下载地址,同时需要修正文件名等

    安装opencv3遇到的问题

    1. 在执行
      sudo sh Ubuntu/3.0/opencv3_0_0.sh
      出现有个地方一直卡住了,显示在下载一个文件: ippicv_linux_20141027.tgz
      因为墙的原因,这个文件无法下载下来
    2. [其他文档] ippicv_linux_20141027.tgz处下载文件 ippicv_linux_20141027.tgz

    3. 下载后拷贝到opencv/3rdparty/ippicv/downloads/linux-8b449a536a2157bcad08a2b9f266828b/ 目录下即

    安装BLAS——选择MKL

    1. 首先下载 MKL(Intel(R) Parallel Studio XE Cluster Edition for Linux 2016)
      网址:https://software.intel.com/en-us/intel-education-offerings
      Caffe + Ubuntu 15.04 + CUDA 7.5 新手安装配置指南作者 Xin-Yu Ou(欧新宇) 可以到他的网盘中下载, 需要自己申请序列号
    2. 下载完成后: parallel_studio_xe_2016.tgz

    3. 执行以下命令:
      $ tar zxvf parallel_studio_xe_2016.tar.gz

      $ chmod a+x parallel_studio_xe_2016 -R

      $ sh install_GUI.sh

    4. 环境配置:
      $ sudo gedit /etc/ld.so.conf.d/intel_mkl.conf
      然后添加以下内容

      /opt/intel/lib/intel64
      /opt/intel/mkl/lib/intel64

      配置生效: sudo ldconfig -v
      安装MKL完成

    5. 修改Makefile.config

    cuDNN安装

    1. cudnn下载
      下载地址:https://developer.nvidia.com/cudnn
      或者到网盘:http://pan.baidu.com/s/1bnOKBO下载
      下载相应文件cudnn-7.0-linux-x64-v4.0-rc.tgz,放到~根目录下

    2. 切换到~目录,执行命令

    $ cd lib64/ $ sudo cp lib* /usr/local/cuda/lib64/ $ cd ../include/ $ sudo cp cudnn.h /usr/local/cuda/$ cd /usr/local/cuda/lib64/ $ sudo rm -r libcudnn.so libcudnn.so.7.0 $ sudo ln -sf libcudnn.so.7.0.64 libcudnn.so.7.0 libcudnn.so $ sudo ldconfig

    重新编译测试caffe

    1. 编译

      sudo make clean
      sudo make all

    2. sample测试: ( 比不使用cudnn快很多)
      sh data/mnist/get_mnist.sh
      sh examples/mnist/create_mnist.sh

    3. 我们可以将迭代次数增加到50000次
      sudo gedit examples/mnist/lenet_solver.prototxt
      修改max_iter: 50000
      最后:
      sh examples/mnist/train_lenet.sh

    sudo vi ~/.bashrc 添加export PYTHONPATH=/home/dl/caffe/python:$PYTHONPATH sudo make pycaffe -j8

    编译matlab接口

    1. 安装matlab2014
      sh /usr/local/MATLAB/R2014a/bin/matlab
    2. Makefile.config 中修改 : MATLAB_DIR := /usr/local/MATLAB/R2014a
    3. sudo make matcaffe -j8

    其他

    1. Vi编辑命令常用vi编辑器命令行

    1. 搜狗输入法安装
      Ubuntu14.04安装搜狗输入法

    2. im-config 然后 ibus选取fcitx

    3. fcitx-config-gtk3
