1、安装显卡驱动
2、安装依赖库(gpu依赖库和caffe依赖库)
sudo apt-get install vim python-pip git
sudo apt-get install build-essential libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler
sudo apt-get install libopenblas-dev liblapack-dev libatlas-base-dev libgflags-dev libgoogle-glog-dev liblmdb-dev
sudo apt-get install libboost-all-dev
sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev
sudo apt-get install freeglut3-devbuild-essentiallibx11-devlibxmu-devlibxi-devlibgl1-mesa-glxlibglu1-mesalibglu1-mesa-dev
3、安装opencv
sudo apt install libopencv-dev python-opencv
4、安装cuda(我装的是9.1)
进入到有cuda安装文件的目录,执行安装文件(确定该目录下有cuda_x.x.x_linux.run文件)
sudo sh ./cuda_x.x.x_linux.run
到安装nvidia驱动确认的时候选择n(如果之前已经安装过了)
5、安装cudnn(只是复制文件加链接,不需要编译安装的过程)
下载对应cuda版本的cudnn
解压出cuda文件夹,在解压出的cuda文件夹目录下
sudo cp lib64/lib* /usr/local/cuda/lib64/
sudo cp include/cudnn.h /usr/local/cuda/include/
cd /usr/local/cuda/lib64/
sudo chmod +r libcudnn.so.x.x.x
sudo ln -sf libcudnn.so.x.x.x libcudnn.so.x
sudo ln -sf libcudnn.so.x libcudnn.so
sudo ldconfig
然后修改环境变量
sudo vim /etc/profile
添加环境变量如下:
export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
source /etc/profile
6、安装caffe
下载caffe
git clone https://github.com/BVLC/caffe.git
进入caffe目录下
sudo cp Makefile.config.example Makefile.config
修改 Makefile.config 文件
sudo vim Makefile.config
(1)CUDA_ARCH设置,因为安装的是9.1,所以删除前两行
-gencode arch=compute_20,code=sm_20\
-gencodearch=compute_20,code=sm_21\
(2)应用cudnn
#USE_CUDNN := 1
to
USE_CUDNN := 1
(3)应用opencv3
#OPENCV_VERSION := 3
to
OPENCV_VERSION := 3
(4)使用python接口
#WITH_PYTHON_LAYER := 1
to
WITH_PYTHON_LAYER := 1
(5)修改python路径
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib
to
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include /usr/include/hdf5/serial
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/hdf5/serial
然后修改caffe目录下的Makefile文件
(1)
NVCCFLAGS +=-ccbin=$(CXX) -Xcompiler-fPIC $(COMMON_FLAGS)
to
NVCCFLAGS += -D_FORCE_INLINES -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS)
(2)
LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_hl hdf5
to
LIBRARIES += glog gflags protobuf boost_system boost_filesystem m hdf5_serial_hl hdf5_serial
然后修改/usr/local/cuda/include/crt/host_config.h文件
#error-- unsupported GNU version! gcc versions later than x.x are not supported!
to
//#error-- unsupported GNU version! gcc versions later than x.x are not supported!
7、编译
caffe目录下执行:
make all
make test
make runtest
注意:
在make runtest可能会出现如下错误:
Makefile:532: recipe for target 'runtest' failed
make: *** [runtest] Error 1
解决办法:修改caffe目录下Makefile文件如下,之后分别make clean,make all,make test,make runntest
# Debugging
ifeq ($(DEBUG), 1)
COMMON_FLAGS += -DDEBUG -g -O0
NVCCFLAGS += -G
else
COMMON_FLAGS += -DNDEBUG -O2
endif
to
# Debugging
ifeq ($(DEBUG), 1)
COMMON_FLAGS += -DDEBUG -g -O0
NVCCFLAGS += -G
else
COMMON_FLAGS += -DNDEBUG -O2
NVCCFLAGS += -G
endif
8、安装pycaffe(caffe的Python接口)
进入目录caffe/python,然后终端执行:
for req in $(cat requirements.txt) --user; do pip install $req; done
然后回到caffe目录,终端执行:
make pycaffe
配置caffe中的python环境:
vim ~/.bashrc
加入以下内容:
export PYTHONPATH=/caffe所在路径/caffe/python:$PYTHONPATH
注意:
for req in $(cat requirements.txt) --user; do pip install $req; done
这句命令如果不加 --user有的会没有权限。在执行过程中也可能会发现缺模块,但是根据提示pip install安装就行。最新版的pip会出现错误如下:
Import Error:cannot import name main
解决方法如下:
sudo vim /usr/bin/pip
之后
from pip import main
if__name__ =='__main__':
sys.exit(main())
to
from pip import__main__
if__name__ =='__main__':
sys.exit(__main__._main())
