Ubuntu 16.4下安裝caffe

1.安裝caffe所需要的依賴包

sudo apt-get install git
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-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

2.下載Caffe源碼：

git clone https://github.com/bvlc/caffe.git
cd caffe/
mv Makefile.config.example Makefile.config

3.修改Makefile和Makefile.config兩個(gè)文件

修改：Makefile.config：（95行左右）
INCLUDE_DIRS := /usr/include $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial/
LIBRARY_DIRS :=/usr/lib $(PYTHON_LIB) /usr/local/lib /usr/lib

打開CPU_ONLY := 1（入門建議先只用cpu訓(xùn)練，進(jìn)階再用gpu）
修改：Makefile：（181行左右）
LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_serial_hl hdf5_serial

4.在caffe根目錄：

make all -j4

5.運(yùn)行手寫識(shí)別過程:在caffe目錄下

cd data/mnist
./get_mnist.sh(若沒有權(quán)限，chmod +x ./get_mnist.sh 賦予權(quán)限) 下載數(shù)據(jù)

6.轉(zhuǎn)換格式

./examples/mnist/create_mnist.sh
7.訓(xùn)練超參數(shù)
在/examples/mnist/lenet_solver.prototxt將mode改為cpu
再運(yùn)行
./build/tools/caffe train --solver=examples/mnist/lenet_solver.prototxt $@
可以看到最后的結(jié)果達(dá)到0.9917
