ubuntu16.04 + caffe + SSD + gpu 安装

昨天我们买好了硬件，今天我们开始安装caffe了，我本人安装过caffe不下10次，每次都是一大堆问题，后来终于总结了关键要点，就是操作系统.

1. 千万不要用ubuntu17.10来安装，

2. 最好的操作系统是ubuntu16.04

如果用17版本的来安装的话，很多时候会遇到要降级gcc的，降级也是非常麻烦的事，因为降级或升级的时候会需要安装很多其他的东西，无形中会打乱整个系统的安装环境，最后到时候又会遇到其他的问题，所以安装caffe的最重要环节是保持一个干净的适合的系统。


 
1.安装CUDA 8.0
安装CUDA之前，先检查机器是否安装了NVIDIA驱动。使用命令
  1. nvidia-smi
查看GPU列表，同时显示了驱动的版本。也可以通过命令
  1. nvidia-settings  nvidia.png

注意上面我的显卡是384.98,后面我们会用到。

查看GPU的详细信息。如果没有安装驱动，则执行下面的命令(注意，我的显卡是GTX1060,所以安装nvidia-384,这个命令要根据你的显卡来安装)
[html] view plain copy
  1. sudo add-apt-repository ppa:graphics-drivers/ppa
  2. sudo apt-get update 
  3. sudo apt-get install nvidia-384
  4. sudo apt-get install mesa-common-dev  
  5. sudo apt-get install freeglut3-dev  
安装NVIDIA的384版本的驱动。
下面开始安装CUDA 8.0。登陆CUDA官网去下载，不过现在官网下载的好像是9的版本，建议下载8的版本，
不要安装9的版本，可能有问题，你打开官网可能会让你安装9的版本，你可以到我的百度盘下载。

上面也同时给出了安装命令：
  1. sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb  
  2. sudo apt-get update  
  3. sudo apt-get install cuda  
注意：在执行上述命令之前，一定要进入安装文件所在的路径，也即是下载的CUDA安装文件所在的地方，一般是/home/Downloads，所以先运行命令
cd Downloads  
然后执行上面三行代码安装CUDA 8.0.


(4)测试CUDA的samples
cd /usr/local/cuda-8.0/samples/1_Utilities/deviceQuery
make
sudo ./deviceQuery
如果显示一些关于GPU的信息，则说明安装成功。

4.配置cuDNN
查看自己电脑显卡的计算能力：https://developer.nvidia.com/cuda-gpus
cuDNN是GPU加速计算深层神经网络的库。
首先去官网 https://developer.nvidia.com/rdp/cudnn-download 下载cuDNN，需要注册一个账号才能下载。下载版本号如下图：
这里写图片描述

我下载了一份，你可以从我的百度盘这里下载。

https://pan.baidu.com/s/1gfzs2bD

下载cuDNN5.1之后进行解压：
sudo tar -zxvf ./cudnn-8.0-linux-x64-v5.1.tgz

cd cuda; sudo cp lib64/lib* /usr/local/cuda/lib64/;
sudo cp include/cudnn.h /usr/local/cuda/include/
更新软连接: cd /usr/local/cuda/lib64/
sudo chmod +r libcudnn.so.5.1.10
sudo ln -sf libcudnn.so.5.1.10 libcudnn.so.5
sudo ln -sf libcudnn.so.5 libcudnn.so
sudo ldconfig

请注意，请到自己解压后的lib64文件夹看这个文件libcudnn.so.5.0.5 ，电脑配置不同后面的数字型号不同，进行相应的修改，否则会报错。


2.配置Caffe
安装好CUDA之后，就可以配置Caffe了。
(1)通过下面的命令安装protobuf，leveldb，snappy，OpenCV，hdf5，boost依赖库
[html] view plain copy
  1. sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler  
  2. sudo apt-get install --no-install-recommends libboost-all-dev  
(2)安装BLAS库
[html] view plain copy
  1. sudo apt-get install libatlas-base-dev  
(3)接着是gflags, glog和lmdb
[html] view plain copy
  1. sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev  
(4)获取Caffe源码

git clone https://github.com/weiliu89/caffe.git
cd caffe
git checkout ssd

 

(5) 配置Caffe
  1. cp Makefile.config.example Makefile.config  
## 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

# BLAS choice:

# 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
# BLAS_LIB := /path/to/your/blas

# Homebrew puts openblas in a directory that is not on the standard search path
# BLAS_INCLUDE := $(shell brew --prefix openblas)/include
# BLAS_LIB := $(shell brew --prefix openblas)/lib

# This is required only if you will compile the matlab interface.
# MATLAB directory should contain the mex binary in /bin.
# MATLAB_DIR := /usr/local
# MATLAB_DIR := /Applications/MATLAB_R2012b.app

# NOTE: this is required only if you will compile the python interface.
# We need to be able to find Python.h and numpy/arrayobject.h.
PYTHON_INCLUDE := /usr/include/python2.7 \
		/usr/lib/python2.7/dist-packages/numpy/core/include
# Anaconda Python distribution is quite popular. Include path:

# 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_LIBRARIES := boost_python3 python3.5m
# PYTHON_INCLUDE := /usr/include/python3.5m \
#                 /usr/lib/python3.5/dist-packages/numpy/core/include

# We need to be able to find libpythonX.X.so or .dylib.
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
# PYTHON_LIB += $(shell brew --prefix numpy)/lib

# Uncomment to support layers written in Python (will link against Python libs)
# WITH_PYTHON_LAYER := 1

# Whatever else you find you need goes here.
# INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
# LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib

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/hdf5/serial/

# If Homebrew is installed at a non standard location (for example your home directory) and you use it for general dependencies
# INCLUDE_DIRS += $(shell brew --prefix)/include
# LIBRARY_DIRS += $(shell brew --prefix)/lib

# NCCL acceleration switch (uncomment to build with NCCL)

# USE_NCCL := 1

# Uncomment to use `pkg-config` to specify OpenCV library paths.
# (Usually not necessary -- OpenCV libraries are normally installed in one of the above $LIBRARY_DIRS.)
# USE_PKG_CONFIG := 1

# N.B. both build and distribute dirs are cleared on `make clean`
BUILD_DIR := build
DISTRIBUTE_DIR := distribute

# Uncomment for debugging. Does not work on OSX due to https://github.com/BVLC/caffe/issues/171
# DEBUG := 1

# The ID of the GPU that 'make runtest' will use to run unit tests.

# enable pretty build (comment to see full commands)
Q ?= @

 

用我上面的Makefile.config就可以了，主要是修改了以下两行.

  1. INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/  
  2. LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu/hdf5/serial/ 
这一步执行没有问题，接着修改/etc/profile文件
su root
-- input password
vi /etc/profile
export PYTHONPATH=$CAFFE_ROOT/python
然后开始运行以下命令

make -j8
make pymake test -j8
make runtest -j8

 

没有报错的话，至此，Caffe已经安装并配置成功了。
