Ubuntu14.04+caffe+cuda8.0+cudnn v5.1配置

前端之家收集整理的这篇文章主要介绍了Ubuntu14.04+caffe+cuda8.0+cudnn v5.1配置前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

1. 环境准备

在Ubuntu下用apt-get大法搞定所有依赖包。opencv和python建议通过别的方法自行安装

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. 安装cuda8.0。从CUDA官网下载目前最新版的cuda8.0的.run文件

安装之前先按下ctrl+alt+F1进入命令行界面,关闭图形界面

sudo stop lightdm

进入到下载的cuda8.0安装包所在文件夹下,直接在命令行运行.run文件开始安装

进入并accept完声明后注意第一个选项,询问你是否需要安装NVIDIA驱动程序,如果电脑已经安装过适合自己显卡的显卡驱动,此处一定得选择为no,后面的基本可以默认选择就好,根据自己需要。如果之前没有安装过NVIDIA驱动则第一个需要选择YES进行驱动的安装然后再进行cuda的安装。

打开图形界面,ctrl+alt+F7回到图形界面:

sudo start lightdm

查看驱动是否安装成功:

nvidia-smi

3. 安装配置cudnn5.1。下载最新的cudnn-8.0-linux-x64-v5.1.tgz文件。将解压出的cuda文件夹下的lib64文件夹里的静态库和动态库文件一并拷到cuda8.0的安装目录下的lib64中去,默认是/usr/local/cuda/lib64/。同时将include文件夹下的头文件cudnn.h拷贝到cuda8.0的include中去,默认为/usr/local/cuda/include/

tar -zxvf cudnn-8.0-linux-x64-v5.1.tgz
cd cuda
sudo cp lib64/* /usr/local/cuda/lib64/
sudo cp include/cudnn.h /usr/local/cuda/include/ 
建立软连接
cd /usr/local/cuda/lib64/
sudo chmod +r libcudnn.so.5.1.5
sudo ln -sf libcudnn.so.5.1.5 libcudnn.so.5
sudo ln -sf libcudnn.so.5 libcudnn.so
sudo ldconfig

4. 设置环境变量

在/etc/profile中添加CUDA环境变量
sudo gedit /etc/profile
文件尾部添加以下内容
PATH=/usr/local/cuda/bin:$PATH
exportPATH
保存后,执行下列命令,使环境变量立即生效
source /etc/profile
同时需要添加lib库路径: 在 /etc/ld.so.conf.d/加入文件 cuda.conf,
sudo gedit /etc/ld.so.conf.d/cuda.conf
添加以下内容

/usr/local/cuda/lib64

保存后,执行下列命令使之立刻生效
sudo ldconfig

此时可以通过命令行查看cuda是否安装成功:

nvcc -V

5. 通过git获取github上的官方caffe源码。

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

6. 配置caffe的config文件

cd caffe/
cp Makefile.config.example Makefile.config  #以example为备份
sudo gedit Makefile.config

根据自己需要进行配置,将cudnn的注释解开,并确保opencv(2或者3),python(或anaconda),cuda等路径的正确

7. 编译caffe

make all && make pycaffe

8. 相对于通过python命令import caffe到python库中,建议是在需要使用caffe的项目中再将库引进去,因为caffe版本可能会有多个,方法如下:

在python文件头部加上

import sys

sys.path.append('/home/yourname/caffe/python')

import caffe

这样caffe即可正常使用了

9. 往python库里导入caffe时可能错误解决情况

(0) ubuntu中很可能碰到的问题,系统的protobuf和pyhton的protobuf版本不一致,可能在C++调用python接口时候遇到问题,此时最好的方法是将python的protobuf版本降回2.6

pip install protobuf==2.6.0

(1)import caffe时出错:can not find module skimage.io

sudo apt-get install python-numpy python-scipy python-matplotlib python-sklearn python-skimage python-h5py python-protobuf python-leveldb python-networkx python-nose python-pandas python-gflags Cython ipython
sudo apt-get update
(2)python caffe libcaffe.so.1.0.0-rc3: cannot open shared object file
cd /etc/ld.so.conf.d
sudo gedit ./pycaffe.conf

在里边添加以下内容

/home/yourname/caffe/build/lib

别忘了再load一下:

sudo ldconfig

然后将caffe/python文件夹下的整个caffe文件夹拷贝到/usr/lib/python2.7/dist-packages下

cd caffe/
sudo cp -r ./python/caffe /usr/lib/python2.7/dist-packages

然后再import caffe就没问题了

(3)python caffe报错:No module named google.protobuf.internal

conda install protobuf

import google.protobuf

最后贴一份opencv3+anaconda3的Makefile.config
