py-R-FCN的caffe配置（转）

参考：https://blog.csdn.net/wei_guo_xd/article/details/74451443

下载程序，
git clone https://github.com/Orpine/py-R-FCN.git
打开py-R-FCN,下载caffe
git clone https://github.com/Microsoft/caffe.git
编译Cython模块
cd lib
make
结果如下图所示：

编译caffe和pycaffe
cd caffe
cp Makefile.config.example MAkefile.config
然后配置Makefile.config文件，可参考我的Makefile.config

结果如下图所示：

下载预训练模型（https://1drv.ms/u/s!AoN7vygOjLIQqUWHpY67oaC7mopf），放到data数据集下，如图所示（第二个是我自己训练的模型）：
运行演示脚本：
./tools/demo_rfcn.py
结果如下图所示：

下载训练，测试，验证数据集：
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtrainval_06-Nov-2007.tar
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCtest_06-Nov-2007.tar
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2007/VOCdevkit_08-Jun-2007.tar
wget http://host.robots.ox.ac.uk/pascal/VOC/voc2012/VOCtrainval_11-May-2012.tar
解压到VOCdevkit文件夹中：
tar xvf VOCtrainval_06-Nov-2007.tar
tar xvf VOCtest_06-Nov-2007.tar
tar xvf VOCdevkit_08-Jun-2007.tar
tar xvf VOCtrainval_11-May-2012.tar
VOCdevkit文件夹的结构如下图所示：

由于py-faster-rcnn不支持多个训练集，我们创造一个新的文件夹叫做VOC0712，把VOC2007和VOC2012里的JPEGImage和Annonation融合到一个单独的文件夹JPEGImage和Annonation里，用下面的程序生成新的ImageSets文件夹：
%writetxt.m
file = dir('F:\VOC0712\Annotations\*.xml');
len = length(file);

num_trainval=sort(randperm(len, floor(9*len/10)));%trainval集占所有数据的9/10，可以根据需要设置
num_train=sort(num_trainval(randperm(length(num_trainval), floor(5*length(num_trainval)/6))));%train集占trainval集的5/6，可以根据需要设置
num_val=setdiff(num_trainval,num_train);%trainval集剩下的作为val集
num_test=setdiff(1:len,num_trainval);%所有数据中剩下的作为test集
path = 'F:\VOC0712\ImageSets\Main\';

fid=fopen(strcat(path, 'trainval.txt'),'a+');
for i=1:length(num_trainval)
s = sprintf('%s',file(num_trainval(i)).name);
fprintf(fid,[s(1:length(s)-4) '\n']);
end
fclose(fid);

fid=fopen(strcat(path, 'train.txt'),'a+');
for i=1:length(num_train)
s = sprintf('%s',file(num_train(i)).name);
fprintf(fid,[s(1:length(s)-4) '\n']);
end
fclose(fid);

fid=fopen(strcat(path, 'val.txt'),'a+');
for i=1:length(num_val)
s = sprintf('%s',file(num_val(i)).name);
fprintf(fid,[s(1:length(s)-4) '\n']);
end
fclose(fid);

fid=fopen(strcat(path, 'test.txt'),'a+');
for i=1:length(num_test)
s = sprintf('%s',file(num_test(i)).name);
if ~isempty(strfind(s,'plain'))
fprintf(fid,[s(1:length(s)-4) '\n']);
end
end
fclose(fid);
为VOCdevkit创造新的超链接：VOCdevkit0712，如下图所示

下载在ImageNet上预训练好的模型，放到./data/imagenet_models里，如下图所示：

下面开始用VOC0712训练：
experiments/scripts/rfcn_end2end.sh 使用联合近似训练
experiments/scripts/rfcn_end2end_ohem.sh 使用联合近似训练+OHEM
experiments/scripts/rfcn_alt_opt_5stage_ohem.sh 使用分布训练+OHEM
./experiments/scripts/rfcn_end2end[_ohem].sh [GPU_ID] [NET] [DATASET] [--set ...]
下面开始用py-rfcn来训练自己的数据集:(我的数据集是标准pascal voc数据集，名字叫做VOC5000)
首先修改网络模型：
1.修改/py-R-FCN/models/pascal_voc/ResNet-50/rfcn_end2end/class-aware/train_ohem.prototxt

layer {

}
}
layer {
bottom: "rfcn_cls"
bottom: "rois"
top: "psroipooled_cls_rois"
name: "psroipooled_cls_rois"
type: "PSROIPooling"
psroi_pooling_param {

}
}
layer {

type: "PSROIPooling"
psroi_pooling_param {
spatial_scale: 0.0625
output_dim: 8#类别数*4
group_size: 7
}
}
2.修改/py-R-FCN/models/pascal_voc/ResNet-50/rfcn_end2end/class-aware/test.prototxt
layer {
bottom: "conv_new_1"
top: "rfcn_cls"
name: "rfcn_cls"
type: "Convolution"
convolution_param {
num_output: 98 #21*(7^2) cls_num*(score_maps_size^2)(类别数+1)*2
kernel_size: 1

}
layer {

type: "PSROIPooling"
psroi_pooling_param {

group_size: 7
}
}

layer {
bottom: "rfcn_bbox"
bottom: "rois"
top: "psroipooled_loc_rois"
name: "psroipooled_loc_rois"
type: "PSROIPooling"
psroi_pooling_param {
spatial_scale: 0.0625
output_dim: 8 #（类别数+1）*4
group_size: 7
}
}
layer {
name: "cls_prob_reshape"
type: "Reshape"
bottom: "cls_prob_pre"
top: "cls_prob"
reshape_param {
shape {
dim: -1
dim: 2 #（类别数+1）
}
}
}

bottom: "bbox_pred_pre"
top: "bbox_pred"
reshape_param {
shape {
dim: -1
dim: 8 #（类别数+1）*4
}
}
}
3.修改/py-R-FCN/lib/datasets/pascal_voc.py
class pascal_voc(imdb):
def __init__(self, image_set, year, devkit_path=None):
imdb.__init__(self, 'voc_' + year + '_' + image_set)
self._year = year
self._image_set = image_set
self._devkit_path = self._get_default_path() if devkit_path is None \
else devkit_path
self._data_path = os.path.join(self._devkit_path, 'VOC' + self._year)
self._classes = ('__background__', # always index 0
'aeroplane')
self._class_to_ind = dict(zip(self.classes, xrange(self.num_classes)))
self._image_ext = '.jpg'
修改self._classes为你的类别加背景。
4./py-R-FCN/lib/datasets/factory.py修改
for year in ['2007', '2012','2001','2002','2006','5000']:
for split in ['train', 'val', 'trainval', 'test']:
name = 'voc_{}_{}'.format(year, split)
__sets[name] = (lambda split=split, year=year: pascal_voc(split, year))
我的数据集叫：VOC5000，所以把5000加到年份当中。
5/py-R-FCN/experiments/scripts/rfcn_end2end_ohem.sh修改
case $DATASET in
pascal_voc)
TRAIN_IMDB="voc_5000_trainval"
TEST_IMDB="voc_5000_test"
PT_DIR="pascal_voc"
ITERS=4000
;;
把训练数据集和测试数据集改为你的数据集，迭代次数改为4000。
开始训练：./experiments/scripts/rfcn_end2end_ohem.sh 0 ResNet-50 pascal_voc

迭代4000次，取得了81.2%的精度。
