Ubuntu 16.04 安装caffe(CPU)以及编译问题处理

首先安装caffe

安装的过程主要参考了赵永科的书深度学习21天实战Caffe中的内容。

主要步骤如下：

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

下载caffe源码：

git clone https://github.com/bvlc/caffe.git
cd caffe/

修改文件名：

mv Makefile.config.example Makefile.config

对文件Makefile.config进行修改，一般在第8行

vim Makefile.config

将CPU_ONLY前的“#”去掉，表示caffe编译时仅支持CPU

编译

make  -j

j 代表使用多线程进行编译，利用所有可以用的CPU，加速编译速度

编译报错整理：

好像出了不少的问题，首先我们看到前几个error，说的其实是一个问题
* error: hdf5.h: No such file or directory *
找不到hdf5.h这个头文件，此时我们可以通过修改Makefile.config文件来解决这个问题：

添加/usr/include/hdf5/serial/ 到 INCLUDE_DIRS
原:

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

改：

# Whatever else you find you need goes here.
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/

此时再进行编译：

lixin@lixin-ThinkPad-E470:~/caffe$ make -j
CXX src/caffe/solver.cpp
CXX src/caffe/solvers/sgd_solver.cpp
CXX src/caffe/net.cpp
CXX src/caffe/layers/hdf5_output_layer.cpp
CXX src/caffe/layers/hdf5_data_layer.cpp
CXX src/caffe/util/hdf5.cpp
AR -o .build_release/lib/libcaffe.a
LD -o .build_release/lib/libcaffe.so.1.0.0
/usr/bin/ld: cannot find -lhdf5_hl
/usr/bin/ld: cannot find -lhdf5
collect2: error: ld returned 1 exit status
Makefile:572: recipe for target '.build_release/lib/libcaffe.so.1.0.0' failed
make: *** [.build_release/lib/libcaffe.so.1.0.0] Error 1

说找不到* lhdf5_hl ， lhdf5 *文件
此时我们需修改Makefile文件，把 hdf5_hl 和hdf5修改hdf5_serial_hl 和 hdf5_serial

vim Makefile

原：

LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_hl hdf5

改：

LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_serial_hl hdf5_serial

再重新编译：

LD -o .build_release/lib/libcaffe.so.1.0.0
CXX/LD -o .build_release/tools/train_net.bin
CXX/LD -o .build_release/tools/extract_features.bin
CXX/LD -o .build_release/tools/device_query.bin

CXX/LD -o .build_release/tools/caffe.bin
CXX/LD -o .build_release/examples/siamese/convert_mnist_siamese_data.bin
CXX/LD -o .build_release/tools/upgrade_solver_proto_text.bin
CXX/LD -o .build_release/tools/convert_imageset.bin
CXX/LD -o .build_release/tools/net_speed_benchmark.bin

CXX/LD -o .build_release/tools/test_net.bin
CXX/LD -o .build_release/examples/mnist/convert_mnist_data.bin
CXX/LD -o .build_release/examples/cpp_classification/classification.bin

完美～
