深度学习21天实战caffe学习笔记《3 ：准备Caffe环境》

准备Caffe环境

【如果是其他环境下的配置就请绕道喽，我也没有专门去试一试各个环境下的配置，请谅解~】

官网 http://caffe.berkeleyvision.org/installation.html；

首先在这里介绍一下我的硬件环境：

Ubuntu 14.04 ---------[ win10远程连接ssh（putty）+VNC ]：

• http://www.ubuntu.com/download/desktop 

gcc 4.8.4   || cuda 7.5.18  ||  

1、安装ssh、vnc；

win10 :  putty   、  VNC

 Unbuntu : sudo apt-get install ssh

 

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进入命令提示符

7. 安装依赖项： 
   sudo service lightdm stop 
   sudo apt-get install g++ 
   sudo apt-get install Git 
   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 cuda_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_14:27:32_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：

    export PATH=/usr/local/cuda-7.5/bin:$PATH
    export LD_LIBRARY_PATH=/usr/local/cuda-7.5/lib64:$LD_LIBRARY_PATH

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 
   在文件尾部添加以下内容

   deb http://archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse
   deb http://archive.ubuntu.com/ubuntu/ trusty-security main restricted universe multiverse
   deb http://archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse
   deb http://archive.ubuntu.com/ubuntu/ trusty-proposed main restricted universe multiverse
   deb http://archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse
   deb-src http://archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse
   deb-src http://archive.ubuntu.com/ubuntu/ trusty-security main restricted universe multiverse
   deb-src http://archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse
   deb-src http://archive.ubuntu.com/ubuntu/ trusty-proposed main restricted universe multiverse
   deb-src http://archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multivers

5. 最后 sudo apt-get update

Q2

W: GPG 错误：http://archive.ubuntukylin.com:10006/ubuntukylin xenial InRelease: 由于没有公钥，无法验证下列签名： NO_PUBKEY 8D5A09DC9B929006

Q3

1080Ti显卡安装完CUDA之后要安装显卡驱动，否则提示找不到显卡设备

sudo service lightdm stop  
sudo chmod 777 NVIDIA-Linux-x86_64-378.13.run   
sudo ./NVIDIA-Linux-x86_64-367.27.run  
sudo service lightdm start

安装caffe

1. 下载caffe：执行命令： sudo git clone https://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：

可以看到诸如

# USE_CUDNN := 1

# Uncomment if you're using OpenCV 3
# OPENCV_VERSION := 3

# BLAS choice:
# atlas for ATLAS (default)
# mkl for MKL
# open for OpenBlas
BLAS := atlas

都是使用默认的设置，我们可以安装其他依赖项提高caffe运行效率

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

   # Uncomment if you're using OpenCV 3
   
   OPENCV_VERSION := 3

7. (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

   arch=$(uname -m)
   if [ "$arch" == "i686" -o "$arch" == "i386" -o "$arch" == "i486" -o "$arch" == "i586" ]; then

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

    # BLAS choice:
       # atlas for ATLAS (default)
       # mkl for MKL
       # open for OpenBlas
       BLAS := mkl

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

   sudo tar xvf cudnn-7.0-linux-x64-v4.0-rc.tgz
   cd cuda/include
   sudo cp *.h /usr/local/include/
   cd ../lib64
   sudo cp lib* /usr/local/lib/
   cd /usr/local/lib
   sudo chmod +r libcudnn.so.4.0.4
   sudo ln -sf libcudnn.so.4.0.4 libcudnn.so.4
   sudo ln -sf libcudnn.so.4 libcudnn.so

cudnn版本问题

在make工程的时候出现以下错误：

...

NVCC src/caffe/layers/deconv_layer.cu
NVCC src/caffe/layers/cudnn_conv_layer.cu
src/caffe/layers/cudnn_conv_layer.cu(81): error: argument of type "cudnnAddMode_t" is incompatible with parameter of type "const void *"
          detected during instantiation of "void caffe::CuDNNConvolutionLayer::Forward_gpu(const std::vector *, std::allocator *>> &, const std::vector *, std::allocator *>> &) [with Dtype=float]" 
(157): here

...

20 errors detected in the compilation of "/tmp/tmpxft_00002703_00000000-16_cudnn_conv_layer.compute_50.cpp1.ii".
make: *** [.build_release/cuda/src/caffe/layers/cudnn_conv_layer.o] Error 1
make: *** Waiting for unfinished jobs....

解决方案：

更换V3版本cudnn Caffe 工程的一些编译错误以及解决方案

$ cd lib64/
$ sudo cp lib* /usr/local/cuda/lib64/
$ cd ../include/
$ sudo cp cudnn.h /usr/local/cuda/include/
$ 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
$ sudo ln -sf 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 
   

编译Python接口
