以及caffe官方Caffe installation instructions说明
http://caffe.berkeleyvision.org/installation.html
一．Caffe installation
如果熟悉上述1,2,3的同学，那么最新版本的Caffe安装基本不会出现什么问题，如有问题请见上述推荐文章。
上述文章可能未覆盖到的问题
error while loading shared libraries: libcudnn.so.5: cannot open shared object file: No such file or directory
原因：自己安装的caffe库文件所在路径未添加到/etc/ld.so.conf文件中
解决方法
进入自己安装的caffe库文件所在位置，并把路径添加到/etc/ld.so.conf文件中
tju@tju-System-Product-Name:~$ cd tju/caffe/build/lib/
tju@tju-System-Product-Name:~/tju/caffe/build/lib$ pwd
/home/tju/tju/caffe/build/lib
tju@tju-System-Product-Name:~/tju/caffe$ cd /etc/ld.so.conf.d/
tju@tju-System-Product-Name:/etc/ld.so.conf.d$ ls -l

tju@tju-System-Product-Name:/etc/ld.so.conf.d$ sudo gedit libcudnn.conf
写入/home/tju/tju/caffe/build/lib
sudo ldconfig
二.我对py-faster-rcnn的作死安装方式
https://github.com/rbgirshick/py-faster-rcnn
讲在前面的话：
- 前置相关依赖项请用terminal安装，尽量不使用类似新立得软件包管理器等安装方式。
- 请先按照原文中的安装流程，先安装Python packages中cython, python-opencv, easydict这样可以减少几个编译中的报错，
安装命令：
sudo apt-get install cython
sudo apt-get install python-opencv
sudo pip install easydict
3. py-faster-rcnn存放位置路径中不能有中文，否则报错UnicodeDecodeError: 'ascii' codec can't decode byte 0xe6 in position
安装py-faster-rcnn
cd 要存放文件的位置
git clone --recursive https://github.com/rbgirshick/py-faster-rcnn.git
cd py-faster-rcnn/lib/
make
删除caffe-faster-rcnn中所有文件
拷贝未经编译过的最新版caffe中所有文件到caffe-faster-rcnn中
cd ../caffe-fast-rcnn/
cd python/
for req in $(cat requirements.txt); do sudo pip install $req; done
cd ..
cp Makefile.config.example Makefile.config
make all -j16
make test -j16
make runtest -j16
跑通
make pycaffe
跑通
把下好的faster_rcnn_models放到py-faster-rcnn/data下
./tools/demo.py
下面神奇的事情发生了，层出不穷的报错，直到我无法解决的错误
1.ImportError: No module named scipy
解决：sudo pip install scipy
2.error: library dfftpack has Fortran sources but no Fortran compiler found
解决：sudo apt-get install gfortran
http://blog.csdn.net/u010551621/article/details/46363853
3.Error parsing text-format caffe.NetParameter: 350:21: Message type "caffe.LayerParameter" has no field named "roi_pooling_param"
ReadProtoFromTextFile(param_file, param) Failed to parse NetParameter file: /home/tju/tju/py-faster-rcnn/models/pascal_voc/VGG16/faster_rcnn_alt_opt/faster_rcnn_test.pt

*** Check failure stack trace: ***
解决：这个问题基本已经百度不到了，换google，中文没找到解决方案，英文中有一个相关问题解答，但是没说如何解决
问题原因：caffe版本不对
基本思路：need to update your build of Caffe and Run upgrade_net.cpp
过程中遇到的一堆问题及解决方法：
tju@tju-System-Product-Name:~/tju/py-faster-rcnn/caffe-fast-rcnn/tools$ gcc upgrade_net_proto_text.cpp
upgrade_net_proto_text.cpp:10:27: fatal error: caffe/caffe.hpp: 没有那个文件或目录
#include "caffe/caffe.hpp"
tju@tju-System-Product-Name:~/tju/py-faster-rcnn/caffe-fast-rcnn/tools sudo nautilus
把py-faster-rcnn/caffe-fast-rcnn/include/caffe下的caffe.hpp移动到/usr/include/

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
make: *** [all] 错误 1
原因：路径中有中文，换个地方放
src/caffe/layer_factory.cpp:
替换文件
/home/tju/tju/software/caffe/src/caffe/layer_factory.cpp
/usr/local/cuda/include/cudnn.h
替换文件
src/caffe/layers/cudnn_tanh_layer.cu
替换文件
src/caffe/layers/cudnn_tanh_layer.cpp:16:45: error: ‘activ_desc_’ was not declared in this scope
cudnn::createActivationDescriptor<Dtype>(&activ_desc_, CUDNN_ACTIVATION_TANH);
caffe旧官方版本对cudnn只支持到特定的版本，不支持最新的V5版本，v5中需要手动修改
include/caffe/layers/cudnn_tanh_layer.hpp, src/caffe/layers/cudnn_tanh_layer.cpp, src/caffe/layers/cudnn_tanh_layer.cu
include/caffe/layers/cudnn_sigmoid_layer.hpp, src/caffe/layers/cudnn_sigmoid_layer.cpp, src/caffe/layers/cudnn_sigmoid_layer.cu
include/caffe/layers/cudnn_relu_layer.hpp, src/caffe/layers/cudnn_relu_layer.cpp, src/caffe/layers/cudnn_relu_layer.cu
src/caffe/layers/cudnn_conv_layer.cu
把原来改成old_的原.cu和.cpp删掉
再gcc就出现了我解决不了的编译问题了… …
Check failed: registry.count(type) == 0 (1 vs. 0) Layer type Convolution already registered.
需要改代码 工作量太大，改到夜里两点半，发现改不动。。。编译时各种报错，放弃这种安装方法
三．简单粗暴的py-faster-rcnn安装方式
通过上述方法，可以得出结论py-faster-rcnn不支持最新版caffe已及最新版cudnn，新版caffe是支持最新版cudnn的，但py-faster-rcnn报错的原因都是因为caffe和cudnn版本各不同引起，或许有大神可以解决，但我强行手动升级没成功，现在告诉大家一种简单粗暴快速的安装方法。
Cuda7.5
cudnn-7.0-linux-x64-v4.0
py-faster-rcnn中自带版本caffe
再按照二中安装py-faster-rcnn方法
就顺利跑通了！
