sudo apt-get install -y python-numpy python-scipy
sudo apt-get install -y python3-pip
sudo apt-get install -y python3-numpy python3-scipy

下载 Caffe

git clone https://github.com/BVLC/caffe.git

Python 环境准备

cd caffe/python/
for req in $(cat requirements.txt); do pip3 install $req; done

修改配置文件

cp Makefile.config.example  Makefile.config
vim Makefile.config

修改 Makefile.config

# CPU_ONLY := 1

CPU_ONLY := 1

# OPENCV_VERSION := 3

OPENCV_VERSION := 3

# PYTHON_INCLUDE := /usr/include/python2.7 \
                /usr/lib/python2.7/dist-packages/numpy/core/include

PYTHON_LIBRARIES := boost_python3 python3.9
PYTHON_INCLUDE := /usr/include/python3.9 \
                 /usr/lib/python3/dist-packages/numpy/core/include
                 
# WITH_PYTHON_LAYER := 1

WITH_PYTHON_LAYER := 1

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

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

修改 Makefile

# 181
LIBRARIES += glog gflags protobuf boost_system boost_filesystem m 

LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_serial_hl hdf5_serial

编译

make all -j4

/usr/bin/ld: cannot find -lboost_system
/usr/bin/ld: cannot find -lboost_filesystem
/usr/bin/ld: cannot find -lboost_thread
collect2: error: ld returned 1 exit status
make: *** [Makefile:583: .build_release/lib/libcaffe.so.1.0.0] Error 1
make: *** Waiting for unfinished jobs....

在文件夹 /usr/lib/x86_64-linux-gnu/ 搜索一下 libboost_system.so 的包，如果可以找到，则执行以下命令，其他几个库同理

sudo ln -s /usr/lib/x86_64-linux-gnu/libboost_system.so.1.65.1 /usr/lib/libboost_system.so

如果找不到，官方给的脚本安装 boost 库是没安装完全的，用下面命令重新安装

sudo apt-get install libboost-all-dev

make pycaffe

/usr/bin/ld: cannot find -lboost_python3
/usr/bin/ld: cannot find -lpython2.7
collect2: error: ld returned 1 exit status
make: *** [Makefile:518: python/caffe/_caffe.so] Error 1

我第一次提示 lboost_python3 lpython2.7 都不存在，完善很多这行都会注释，打开这行，lpython2.7 问题解决

PYTHON_LIBRARIES := boost_python3 python3.9

在caffe编译配置文件 Makefile.config 里面的 PYTHON_LIBRARIES := boost_python3 python3.6m 一行中，找不到 boost_python3 造成的

同理在文件夹 /usr/lib/x86_64-linux-gnu/ 搜索一下 libboost_python3.9.so 文件，如果存在则

sudo ln -s libboost_python39.so libboost_python3.so
sudo ln -s libboost_python39.a libboost_python3.a

如果不存在，需要自己编译一个，给链接自己去编译吧 教程

环境变量

具体加在那个配置文件自己决定

sudo vim ~/.profile

合适地方添加，caffe_path 就是 caffe 在你电脑位置

export PYTHONPATH=caffe_path/caffe/python:$PYTHONPATH

刷新环境变量

source ~/.profile

验证

python
> import caffe
