ubuntu16.04 安装caffe（GPU）

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler

sudo apt-get install --no-install-recommends libboost-all-devsudo apt-get install libatlas-base-dev

sudo apt-get install python-skimage ipython python-pil python-h5py ipython python-gflags python-yaml 

sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev

sudo apt-get install git
git clone https://github.com/BVLC/caffe.git[/code]修改Makefile.config： 
cp Makefile.config.example Makefile.config
gedit Makefile.config
以下需要修改三个地方

使用GPU版本：

将
#USE_CUDNN := 1
修改成：
USE_CUDNN := 1


使用python接口：

将
#WITH_PYTHON_LAYER := 1
修改为
WITH_PYTHON_LAYER := 1


修改python路径：

INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib
修改为：
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

然后修改 caffe 目录下的 Makefile 文件：

将：
NVCCFLAGS +=-ccbin=$(CXX) -Xcompiler-fPIC $(COMMON_FLAGS)
替换为：
NVCCFLAGS += -D_FORCE_INLINES -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS)
将：
LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_hl hdf5
改为：
LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_serial_hl hdf5_serial
将
#error-- unsupported GNU version! gcc versions later than 4.9 are not supported!
改为
//#error-- unsupported GNU version! gcc versions later than 4.9 are not supported!
OK ，可以开始编译了，在 caffe 目录下执行 

make all -j32
编译成功后可运行测试：

sudo make runtest -j32

 python 来操作 caffe

cd caffe

sudo make pycaffe -j32
sudo echo export PYTHONPATH="~/caffe/python" >> ~/.bashrc

source ~/.bashrc


成功！
