opencv3 與cuda8不兼容，不啟動支持cuda 真的是歷經千辛啊
安裝依賴庫sudo apt-get install cmake git pkg-config libgtk2.0-dev libavcodec-dev libavformat-dev libswscale-dev sudo apt-get install python-dev python-openCV python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-devbuildmkdir buildcd buildcmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..cmake成功后，會出現如下結果，提示配置和生成成功： – Configuring done – Generating done 由于CUDA 8.0不支持OpenCV的 GraphCut 算法，可能出現以下錯誤：
~/opencv3.1.0/modules/cudalegacy/src/graphcuts.cpp:120:54: error: 'NppiGraphcutState' has not been declaredtypedef NppStatus (*init_func_t)(NppiSize oSize, NppiGraphcutState** ppStat^/home/usrname/opencv-3.1.0/modules/cudalegacy/src/graphcuts.cpp:135:18: error: 'NppiGraphcutState' does not name a typeOperator NppiGraphcutState*()^
【解決辦法】進入opencv-3.1.0/modules/cudalegacy/src/目錄，修改graphcuts.cpp文件，將：
#include "precomp.hpp"#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER)改為
#include "precomp.hpp"#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER) || (CUDART_VERSION >= 8000)然后make編譯就可以了
make -j8sudo make installhttps://github.com/BVLC/caffe 下載caffe-master.zip
在 caffe-master/python，如果是python2運行
for req in $(cat requirements.txt); do sudo pipinstall $req; done如果是python3，則把pip改為pip3
for req in $(cat requirements.txt); do pip3 install $req; done下面是我用 diff Makefile.config Makefile.config.example 比較出來的結果
runtest可能會遇到錯誤 libcudart.so.6.5: cannot open shared object file: No such file or directory. 執行以下操作
sudo cp /usr/local/cuda-8.0/lib64/libcudart.so.8.0 /usr/local/lib/libcudart.so.8.0 && sudo ldconfigsudo cp /usr/local/cuda-8.0/lib64/libcublas.so.8.0 /usr/local/lib/libcublas.so.8.0 && sudo ldconfigsudo cp /usr/local/cuda-8.0/lib64/libcurand.so.8.0 /usr/local/lib/libcurand.so.8.0 && sudo ldconfigsudo cp /usr/local/cuda-8.0/lib64/libcudnn.so.5 /usr/local/lib/libcudnn.so.5 && sudo ldconfigmake pycaffemake pycaffe如果遇到錯誤 /usr/bin/ld: cannot find -lboost_python3
執行
cd /usr/lib/x86_64-linux-gnu/sudo ln -s libboost_python-py35.so libboost_python3.sopython3.5的datautil/rrule.py里的raiseError有語法錯誤，要自己手動修改，把raiseError后面的語句用括號括起來
設置python caffe的路徑
cd caffe-master/python pwd
sudo gedit ~/.bashrc 添加 export PYTHONPATH=/home/chuny/caffe-master/python:$PYTHONPATH 保存后 source ~/.bashrc
【注意】 編譯一次caffe,只能支持python2或python3 安裝python的時候，用sudo pip install是安裝在根目錄下，直接用pip安裝的是在當前用戶的home里面，其他用戶用不了
