cuda8+cuDNN Faster R-CNN安装塈运行demo

安装cuda

cuda8安装参见网上教程

安装cuDNN

py-faster-rcnn/caffe-fast-rcnn目前不支持cuDNN5。
如果使用cuDNN5，在编译caffe-fast-rcnn时会报错：

error: argument of type “int” is incompatible with parameter of type “cudnnNanPropagation_t”
解决编译错误的方法参见我的另一篇博客：
《使用cuDNN5编译py-faster-rcnn错误：cudnn.hpp(126): error: argument of type “int” is incompatible …》

如果使用cuDNN4就不会有编译错误。
cuDNN安装方式(cuDNN4为例)

tar zxvf cudnn-7.0-linux-x64-v4.0-prod.tgz 
sudo cp cuda/include/cudnn.h /usr/local/cuda/include 
sudo cp -d cuda/lib64/libcudnn* /usr/local/cuda/lib64 

cuDNN4 OR 5？

那么应该安装cuDNN4还是cuDNN5呢？
这取决于你的NVIDIA显卡与cuDNN之间是否有兼容性问题。
如果你的电脑上用cuDNN4能正常执行demo，那自然好，
如果不能，就换cuDNN5试试，原因参见我的另一篇博客
《cuDNN兼容性问题造成的caffe/mnist,py-faster-rcnn/demo运行结果错误》

下载faster r-cnn代码

$git clone --recursive https://github.com/rbgirshick/py-faster-rcnn.git

下载模型数据

模型数据有点大，要花点时间

$./data/scripts/fetch_faster_rcnn_models.sh

编译caffe

这里的caffe是Faster R-CNN自带的caffe，在caffe-fast-rcnn文件夹下

$cd caffe-fast-rcnn
#如果没有cmake，要安装cmake
#$sudo apt-get install cmake
# 执行cmake生成Makefile
#编译CPU版本
#cmake -DCPU_ONLY=ON -DBLAS=Open .
#编译GPU版本
$cmake -DBLAS=Open -DCUDA_NVCC_FLAGS=--Wno-deprecated-gpu-targets .
$make -j 8

关于编译caffe的细节参见我的另一篇博客 《Ubuntu16:cmake生成Makefile编译caffe过程(OpenBLAS/CPU+GPU)塈解决nvcc warning:The ‘compute_20’, ‘sm_20’》

安装pycaffe的依赖库

caffe-fast-rcnn/python/requirement.txt文件列出了pycaffe的所有依赖库，要把requirements下的依赖都装一遍

guyadong@10km-ubuntu:~/tmp/py-faster-rcnn/caffe-fast-rcnn/python$ cat requirements.txt
Cython>=0.19.2
numpy>=1.7.1
scipy>=0.13.2
scikit-image>=0.9.3
matplotlib>=1.3.1
ipython>=3.0.0
h5py>=2.2.0
leveldb>=0.191
networkx>=1.8.1
nose>=1.3.0
pandas>=0.12.0
python-dateutil>=1.4,<2
protobuf>=2.5.0
python-gflags>=2.0
pyyaml>=3.10
Pillow>=2.3.0

pycaffe的依赖库是用Python的包管理工具pip来安装的,如果还没安装pip，则要先安装python-pip

$ sudo apt-get install python-pip
$ sudo apt-get install python-opencv
$ sudp apt-get install python-tk
$ sudo apt-get install python-dateutil
$ cd caffe-fast-rcnn/python
$ for req in $(cat requirements.txt); do sudo pip install $req; done
$ sudo pip install easydict

编译faster-rcnn

编译好caffe-fast-rcnn后，在py-faster-rcnn/lib中执行make命令：

如果在CPU上运行，要复杂一些，需要手工修改一些脚本，参见《Faster R-CNN CPU环境搭建》.
