如何才能将Faster R-CNN训练起来?
首先进入 Faster RCNN 的官网啦,即:https://github.com/rbgirshick/py-faster-rcnn#installation-sufficient-for-the-demo
先用提供的 model 自己测试一下效果嘛。。。
按照官网安装教程,安装基本需求。
Installation (sufficient for the demo)
- Clone the Faster R-CNN repository
# Make sure to clone with --recursive git clone --recursive https://github.com/rbgirshick/py-faster-rcnn.git
- We'll call the directory that you cloned Faster R-CNN into
FRCN_ROOT
Ignore notes 1 and 2 if you followed step 1 above.
Note 1: If you didn't clone Faster R-CNN with the
--recursive
flag, then you'll need to manually clone thecaffe-fast-rcnn
submodule:git submodule update --init --recursive
Note 2: The
caffe-fast-rcnn
submodule needs to be on thefaster-rcnn
branch (or equivalent detached state). This will happen automatically if you followed step 1 instructions. - Build the Cython modules
cd $FRCN_ROOT/lib make
- Build Caffe and pycaffe
cd $FRCN_ROOT/caffe-fast-rcnn # Now follow the Caffe installation instructions here: # http://caffe.berkeleyvision.org/installation.html # If you're experienced with Caffe and have all of the requirements installed # and your Makefile.config in place, then simply do: make -j8 && make pycaffe
- Download pre-computed Faster R-CNN detectors
cd $FRCN_ROOT ./data/scripts/fetch_faster_rcnn_models.sh
This will populate the
$FRCN_ROOT/data
folder withfaster_rcnn_models
. Seedata/README.md
for details. These models were trained on VOC 2007 trainval.
Demo
After successfully completing basic installation, you'll be ready to run the demo.
To run the demo
cd $FRCN_ROOT ./tools/demo.py
The demo performs detection using a VGG16 network trained for detection on PASCAL VOC 2007.
你自己要下载一个 caffe-master,因为这个检测方法就是调用 caffe的啦,自己下载了,然后放到(注意,是拷贝内容):
./py-faster-rcnn-master/caffe-fast-rcnn/
然而,情况总是不太顺利啊,遇到了如下问题:
执行 demo 的过程中,遇到的首个问题是:
wangxiao@GTX980:~/Desktop/py-faster-rcnn-master$ ./tools/demo.py
Traceback (most recent call last):
File "./tools/demo.py", line 18, in <module>

import skimage.io
ImportError: No module named skimage.io
wangxiao@GTX980:~/Desktop/py-faster-rcnn-master$
解决方法是: sudo easy_install -U scikit-image
那么,就这样完了?? 噢,no,并不是:
wangxiao@GTX980:~/Desktop/py-faster-rcnn-master/tools$ ./demo.py
/usr/local/lib/python2.7/dist-packages/matplotlib-2.0.0b3-py2.7-linux-x86_64.egg/matplotlib/font_manager.py:279: UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.

IOError: /home/wangxiao/Desktop/py-faster-rcnn-master/data/faster_rcnn_models/VGG16_faster_rcnn_final.caffemodel not found.
Did you run ./data/script/fetch_faster_rcnn_models.sh?
因为你测试的时候,没有提供给他测试的 model啊,ok,执行这句吧,下载一个模型:
./data/script/fetch_faster_rcnn_models.sh
速度还是有点慢的,耐心等候啊,少年!
然后,
wangxiao@GTX980:~/Desktop/py-faster-rcnn-master/tools$ ./demo.py

wangxiao@GTX980:~/Desktop/py-faster-rcnn-master/tools$
我更新了一下系统,但是提示我无法更新啊。。。
wangxiao@GTX980:~$ sudo apt-get update
[sudo] password for wangxiao:
E: Type 'Reading' is not known on line 1 in source list /etc/apt/sources.list.d/bazel.list
E: The list of sources could not be read.
进去这个路径,将这个文件删掉,即可,即:sudo rm /etc/apt/sources.list.d/bazel.list
之前出现各种蛋疼的情况主要是因为:不能自己从caffe官网下的那个caffe来用,而应该是从作者自己的 github上来下。
然后加到对应的文件夹进行编译,就不会出现这些问题了。
至于训练的话,有两种方式,一种是: end-to-end,即:
在终端执行:选择 GPU-0,网络为: ZF 数据集为: pascal_voc
./experiments/scripts/faster_rcnn_end2end.sh 0 ZF pascal_voc
那么,就可以跑了 。。。
不像 matlab版本那么蛋疼,跑一下,就会自动关闭matlab一次,╮(╯▽╰)╭ 伤不起 。。。
这是最终跑出来的结果:mAP 是:59.09 %

Matlab 版本碰到过如下的问题:
1. 找不到 ZF文件夹下面的 test.prototxt 文件:
fast_rcnn startup done
GPU 1: free memory 3786178560
Use GPU 1
Error using CHECK_FILE_EXIST (line 4)
/home/wangxiao/Desktop/matlab-faster_rcnn-master/experiments/models/rpn_prototxts/ZF/test.prototxt does not exist
Error in caffe.get_net (line 21)
CHECK_FILE_EXIST(model_file);
Error in caffe.Net (line 31)
self = caffe.get_net(varargin{:});
Error in proposal_calc_output_size (line 10)
caffe_net = caffe.Net(test_net_def_file, 'test');
Error in script_faster_rcnn_VOC2007_ZF>proposal_prepare_anchors (line 91)

Error in script_faster_rcnn_VOC2007_ZF (line 41)
[conf_proposal.anchors, conf_proposal.output_width_map, conf_proposal.output_height_map] ...
解决方案是:没有下载那个文件,囧,下载地址:https://onedrive.live.com/download?resid=36FEC490FBC32F1A!113&authkey=!AIzdm0sD_SmhUQ4&ithint=file%2czip
2. 将上一个问题搞定后,有出现新的,这个有点摸不着头脑了:
fast_rcnn startup done
GPU 1: free memory 3761143808
Use GPU 1
No appropriate method, property, or field reshape_as_input for class caffe.Net.
Error in proposal_calc_output_size (line 28)

Error in script_faster_rcnn_VOC2007_ZF (line 41)
[conf_proposal.anchors, conf_proposal.output_width_map, conf_proposal.output_height_map]
...
解决方法是:可能是你 caffe 版本不对,重新从 faster rcnn 官网上下载,然后编译 。。。
3. 更蛋疼的是这个问题,表面上看,正在运行,但是 这个时候你看看终端上的显示:
File not found: ./models/rpn_prototxts/ZF/train_vali.prototxt
但是,这个文件明明就放在那里啊。。。无语。。。
解决方案是:由于下载的model中,关于 prototxt文件中路径的问题,请改为绝对路径,如下图所示,且用”/“作为分隔符,因为下载了的分隔符是不对的,所以,一直找不到这个文件,哎,坑啊。。。。
搞完之后,就可以继续正常的运行了。。。

4. Faster RCNN 运行出现问题:
fast_rcnn startup done
Error using gpuDevice (line 26)
An unexpected error occurred during CUDA execution. The CUDA error was:
cannot set while device is active in this process
Error in auto_select_gpu (line 15)
g = gpuDevice(i);
Error in script_faster_rcnn_VOC2007_ZF (line 16)
opts.gpu_id = auto_select_gpu;
答:如果之前正常运行,突然出现这个问题,重启你的 matlab,然后以 sudo 开启,重新跑一下就没事了。。。
5. 下面是今天重新跑 faster RCNN 遇到的一个问题:
解决方案是:
数据集的名字或者文件夹不存在,额,将数据集加上就行了...
6. 之前一直很纳闷,script_faster_rcnn_VOC0712_VGG16.m 这个脚本的数据集该怎么设置? 是分别单独设置两个文件夹,还是将其放到一个文件夹中???
看到这个代码,我终于恍然大悟 ...
