ubuntu16.04 安装caffe cpu版本 python3

• sudo vim /etc/apt/sources.list 更换国内源，速度比较快。以下是阿里云源。

• sudo apt update , sudo apt upgrade更新系统。

• 安装依赖文件。

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

• git clone https://github.com/BVLC/caffe.git 下载caffe源码。

• 修改Makefile文件。

 cd ~/caffe-master
 cp Makefile.config.example Makefile.config
 vim Makefile.config

	删除 `#CPU_ONLY := 1` 的#,开启仅使用cpu。

	以下两行带有hdf5的为新增加的内容，解决无法找到HD5的错误。

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

	使用python3还需做如下修改，将PYTHON_INCLUDE python2的注释掉，取消python3的注释。

		#python2
		#PYTHON_INCLUDE := /usr/include/python2.7 \
                /usr/lib/python2.7/dist-packages/numpy/core/include
        #python3
		PYTHON_LIBRARIES := boost_python3 python3.5m
		PYTHON_INCLUDE := /usr/include/python3.5m \
                /usr/lib/python3/dist-packages/numpy/core/include
       

	解决`/usr/bin/ld: cannot find -lboost_python3` 错误

sudo ln -s /usr/lib/x86_64-linux-gnu/libboost_python-py35.so /usr/lib/x86_64-linux-gnu/libboost_python3.so 

	编译caffe,make默认单核运算，-j2表示双核，可加快速度，根据自己实际情况修改。

make all -j2
make test -j2
make runtest -j2

• 安装caffe python3接口。

sudo apt install python3-pip #安装pip工具。
sudo apt install python3-numpy #解决后面编译无法找到numpy错误。
sudo apt-get install gfortran #安装依赖文件
sudo pip3 install matplotlib#解决后面import caffe报错

cd ~/caffe-master
pip3 install -r python/requirements.txt 

	编译

make pycaffe -j2

打开python3终端测试:

cd ~/caffe-master/python/
python3
import caffe #不报错则安装成功.

• 增加环境变量

vim ~/.bashrc
添加一行   export PYTHONPATH=~/caffe-master/python:$PYTHONPATH
