ubuntu16.04+cuda8.0+caffe

===========
如果出现nvidia-smi failed to communicate with nvidia driver,循环登录情况,则:
sudo apt-get remove --purge nvidia-*
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo service lightdm stop
cd packages
重新安装:
sudo sh ./NVIDIA-Linux-x86_64-390.59.run -no-opengl-files
安装显卡驱动

===

1.测试cuda8.0是否安装成功

ls /dev/nvidia*

显示四个或者三个

2.cudnn安装

2.1 下载好文件,进入下载目录 (cudnn5.1)

tar zxvf cudnn-8.0-linux-x64-v5.1.tgz
解压后有个cuda文件,内有include和lib64两个文件夹,进入include文件夹,执行如下命令复制头文件:

cd ../cuda/include/
sudo cp cudnn.h /usr/local/cuda/include/

再cd命令切换进lib64文件夹,执行如下命令复制动态链接库:

cd ../lib64/
sudo cp lib* /usr/local/cuda/lib64/

然后进入复制后的动态链接库进行新的链接。先进入目录:
cd /usr/local/cuda/lib64/

查看已有链接:
ls -al | grep libcudnn
显示四个
删除原有动态文件:
sudo rm -rf libcudnn.so libcudnn.so.5
再次查看:
ls -al | grep libcudnn
显示两个,说明已删除,现在建立新的链接:

sudo ln -s libcudnn.so.5.1.5 libcudnn.so.5
sudo ln -s libcudnn.so.5 libcudnn.so

2.2 下载好文件,进入下载目录 (cudnn6.0)

tar zxvf cudnn-8.0-linux-x64-v6.0.tgz
解压后有个cuda文件,内有include和lib64两个文件夹,进入include文件夹,执行如下命令复制头文件:

sudo cp cuda/include/cudnn.h /usr/local/cuda/include/ 
sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64/ 
sudo chmod a+r /usr/local/cuda/include/cudnn.h 
sudo chmod a+r /usr/local/cuda/lib64/libcudnn*

然后进入复制后的动态链接库进行新的链接。先进入目录:
cd /usr/local/cuda/lib64/

查看已有链接:
ls -al | grep libcudnn
显示四个
删除原有动态文件:
sudo rm -rf libcudnn.so libcudnn.so.6
再次查看:
ls -al | grep libcudnn
显示两个,说明已删除,现在建立新的链接:
sudo ln -s libcudnn.so.6.0.21 libcudnn.so.6
sudo ln -s libcudnn.so.6 libcudnn.so

再次查看:
ls -al | grep libcudnn
显示四个,已链接好!
然后设置环境变量和动态链接库:
sudo gedit /etc/profile
然后再打开的文件末尾加上(“=”前后不要有空格)
export PATH=/usr/local/cuda/bin:$PATH

保存之后创建链接文件:
sudo vim /etc/ld.so.conf.d/cuda.conf
这是一个空白文件,添加:
/usr/local/cuda/lib64
按下esc键,输入(:wq)保存并退出
输入如下命令使链接生效
sudo ldconfig

3.安装caffe相关依赖

sudo apt-get install git libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler libatlas-base-dev python-dev libgflags-dev libgoogle-glog-dev liblmdb-dev
sudo apt-get install --no-install-recommends libboost-all-dev

安装python依赖库
sudo apt-get install cython python-numpy python-scipy python-skimage python-scikits-learn python-matplotlib ipython python-h5py python-leveldb python-networkx python-nose python-pandas python-dateutil python-protobuf python-gflags python-yaml python-pil

安装矩阵加速器
[sudo] apt-get install libopenblas-dev

4.安装caffe:

从官网下载caffe-master压缩包,解压到自己想要的目录
进入主目录下
cp Makefile.config.example Makefile.config

Vim Makefile.config
修改BLAS:=open
use_cudnn :=1的备注取消

修改下面配置:

`NCLUDE_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/ `

(好象是在200行左右)

====

5.编译测试

make all -j8
make test -j8
make runtest -j8
make pycaffe

=======

6.测试

下载MNIST数据库并解压缩
./data/mnist/get_mnist.sh

将其转换成Lmdb数据库格式

./examples/mnist/create_mnist.sh

训练网络

./examples/mnist/train_lenet.sh

结果显示:

==========

错误集锦

1.make all -j8出现错误:

/usr/bin/ld: cannot find -lhdf5_hl
/usr/bin/ld: cannot find -lhdf5
collect2: error: ld returned 1 exit status

这说明连接器找不到 hdf5_hl和hdf5这两个库,没法进行链接。
我的解决方案是更改makefile:在makefile中作如下更改:

#LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_hl hdf5
LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_serial_hl hdf5_serial

(把第一行注释,然后改成第二行的内容就可以了)'

2.make all -j8出现错误:

进入caffe根目录,
gedit Makefile.config
设置以下内容:

    USE_CUDNN := 1 #取消该句注释     
    PYTHON_INCLUDE := /usr/include/python2.7 \     
    /usr/lib/python2.7/dist-packages/numpy/core/include    
    WITH_PYTHON_LAYER := 1 #取消注释    
    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  

3.make all -j8出现错误:

CXX .build_release/src/caffe/proto/caffe.pb.cc
In file included from .build_release/src/caffe/proto/caffe.pb.cc:5:0:
.build_release/src/caffe/proto/caffe.pb.h:9:42: fatal error: google/protobuf/stubs/common.h: 没有那个文件或目录
 #include <google/protobuf/stubs/common.h>
compilation terminated.
Makefile:588: recipe for target '.build_release/src/caffe/proto/caffe.pb.o' failed
make: *** [.build_release/src/caffe/proto/caffe.pb.o] Error 1

可能是依赖包没有下载完全,重新回到步骤三,逐个测试安装

4.make all -j8出现错误:

/sbin/ldconfig.real: /usr/lib/nvidia-375/libEGL.so.1 不是符号连接
/sbin/ldconfig.real: /usr/lib32/nvidia-375/libEGL.so.1 不是符号连接

原因:

系统找的是一个符号连接,而不是一个文件。

解决方法:

sudo mv /usr/lib/

nvidia-375/libEGL.so.1 /usr/lib/nvidia-375/libEGL.so.1.org
sudo mv /usr/lib32/nvidia-375/libEGL.so.1 /usr/lib32/nvidia-375/libEGL.so.1.org
sudo ln -s /usr/lib/nvidia-375/libEGL.so.375.39 /usr/lib/nvidia-375/libEGL.so.1
sudo ln -s /usr/lib32/nvidia-375/libEGL.so.375.39 /usr/lib32/nvidia-375/libEGL.so.1

5.make all -j8出现错误:

Makefile:588: recipe for target ‘.build_release/cuda/src/caffe/layers/embed_layer.o’ failed
make: * [.build_release/cuda/src/caffe/layers/embed_layer.o] Error 1
/usr/include/string.h: In function ‘void* __mempcpy_inline(void*, const void*, size_t)’:
/usr/include/string.h:652:42: error: ‘memcpy’ was not declared in this scope
return (char *) memcpy (__dest, __src, __n) + __n;

这个问题疑似跟Ubuntu16.04的版本有关系,
在caffe的Makefile里面第409行

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

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

6.make all -j8出现错误:

fatal error: hdf5.h: 没有那个文件或目录

解决方案:
1)在Makefile.config文件的第85行,添加/usr/include/hdf5/serial/ 到 INCLUDE_DIRS,也就是把下面第一行代码改为第二行代码。

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/

2)在Makefile文件的第173行,把 hdf5_hl 和hdf5修改为hdf5_serial_hl 和 hdf5_serial,也就是把下面第一行代码改为第二行代码。

LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_hl hdf5

LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_serial_hl hdf5_serial

7.make all -j8出现错误:

build_release/lib/libcaffe.so: undefined reference to google::protobuf::internal::WireFormatLite::WriteStringMaybeAliased(int, std::string const&, google::protobuf::io::CodedOutputStream*)'

设置环境变量:LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/:$LD_LIBRARY_PATH,将/usr/lib/x86_64-linux-gnu/放在最前面

8.make all -j8出现错误:

build_release/lib/libcaffe.so: undefined reference to `google::protobuf::io::CodedOutputStream::WriteStringWithSizeToArray(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned char*)'

.build_release/lib/libcaffe.so: undefined reference to `google::protobuf::Message::InitializationErrorString[abi:cxx11]() const'

.build_release/lib/libcaffe.so: undefined reference to `google::protobuf::internal::NameOfEnum[abi:cxx11](google::protobuf::EnumDescriptor const*, int)'

.build_release/lib/libcaffe.so: undefined reference to `google::base::CheckOpMessageBuilder::NewString[abi:cxx11]()'

原因:
应该是安装anaconda了,而且在里面安装了protobuf相关的东西,和系统里安装的冲突了
解决方法:
将系统环境中的anaconda路径先注释掉,就可以成功make
gedit ~/.bashrc
备注掉anaconda的路径
