cudnn 5.1版本下跑通 py-faster-rcnn的demo

孟意致
2023-12-01

软件环境:

Ubuntu 16.04 + CUDA8.0 + cuDnn5.1 + python 2.7 + OpenCv 3.1


本文的主要目的,是解决在编译py-faster-rcnn的过程中,与cuDnn的v5版本的冲突问题。编译报错是函数错用。最初是把cuDnn换成了v4。后期在跑demo.py时,没能正确检测出物体,也就是没有出带框的图像。一开始以为是plt的问题,后来发现不是,此demo.py在cpu下运行正常,加上gpu选项就不能正常检测物体。


第一阶段,是按照py-faster-rcnn作者的前半部分步骤来进行。相关链接


1.作者提到,在编译Caffe时,至少需要在Makefile.config设置的两点,这里和Caffe的安装相关了,有很多这样的教程。

# In your Makefile.config, make sure to have this line uncommented
WITH_PYTHON_LAYER := 1
# Unrelatedly, it's also recommended that you use CUDNN
USE_CUDNN := 1

2.你需要安装的软件(用apt-get即可):

cython, python-opencv, easydict

3.命令行下

# Make sure to clone with --recursive
git clone --recursive https://github.com/rbgirshick/py-faster-rcnn.git
4. $FRCN_ROOT指克隆过来的根目录

cd $FRCN_ROOT/lib
make

==========================================================================分界线==========================================

5.作者用的caffe的版本较旧,为了能和cuDnn v5兼容,需要参考:这里

cd caffe-fast-rcnn  
git remote add caffe https://github.com/BVLC/caffe.git  
git fetch caffe  
git merge -X theirs caffe/master  

整合以后,需要修改:

Remove self_.attr("phase") = static_cast<int>(this->phase_); from include/caffe/layers/python_layer.hpp after merging.

========================================分界线============================================================================

6.回到原作者的教程。为编译做准备。原作者的Makefile.config文件我不建议用,他里面有一些老旧的设定,比如gcc版本,Matlab的一些设定。我贴上我的来,并把一些坑具体的说说,其实这个配置文件每一项猜起来比较容易。

cd $FRCN_ROOT/caffe-fast-rcnn
在这个目录下我们需要准备Makefile.config文件

Q ?= @

编辑好Makefile.config文件以后可以执行:

make -j8 && make pycaffe
在执行过程中,难免会有错误,比如少xx.h,有可能你真的没有装相关的软件,有可能你有但没被发现。可通过find命令进行寻找。

find /usr -name xxx.h
这是在/usr里进行寻找。这类错误比较容易解决。

7. 下面就是下载模型(脚本需要运行两次)和跑demo.py了

cd $FRCN_ROOT
./data/scripts/fetch_faster_rcnn_models.sh
./data/scripts/fetch_faster_rcnn_models.sh

./tools/demo.py
