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:
make pycaffe
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.mfile = 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']);endfclose(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']);endfclose(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']);endfclose(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']);endendfclose(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
name: "ResNet-50"layer { name: 'input-data' type: 'Python' top: 'data' top: 'im_info' top: 'gt_boxes' python_param { module: 'roi_data_layer.layer' layer: 'RoIDataLayer' param_str: "'num_classes': 2" #改为你的数据集的类别数+1 }}layer { name: 'roi-data' type: 'Python' bottom: 'rpn_rois' bottom: 'gt_boxes' top: 'rois' top: 'labels' top: 'bbox_targets' top: 'bbox_inside_weights' top: 'bbox_outside_weights' python_param { module: 'rpn.proposal_target_layer' layer: 'ProposalTargetLayer' param_str: "'num_classes': 2"#改为你的数据集的类别数+1 }}layer { bottom: "conv_new_1" top: "rfcn_cls" name: "rfcn_cls" type: "Convolution" convolution_param { num_output: 98 #2*(7^2) cls_num*(score_maps_size^2)(类别数+1)*49 kernel_size: 1 pad: 0 weight_filler { type: "gaussian" std: 0.01 } bias_filler { type: "constant" value: 0 } } param { lr_mult: 1.0 } param { lr_mult: 2.0 }}layer { bottom: "conv_new_1" top: "rfcn_bbox" name: "rfcn_bbox" type: "Convolution" convolution_param { num_output: 392 #8*(7^2) cls_num*(score_maps_size^2)(类别数+1)*49*4 kernel_size: 1 pad: 0 weight_filler { type: "gaussian" std: 0.01 } bias_filler { type: "constant" value: 0 } } param { lr_mult: 1.0 } param { lr_mult: 2.0 }}layer { bottom: "rfcn_cls" bottom: "rois" top: "psroipooled_cls_rois" name: "psroipooled_cls_rois" type: "PSROIPooling" psroi_pooling_param { spatial_scale: 0.0625 output_dim: 2 #类别数+1 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*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 pad: 0 weight_filler { type: "gaussian" std: 0.01 } bias_filler { type: "constant" value: 0 } } param { lr_mult: 1.0 } param { lr_mult: 2.0 }}layer { bottom: "conv_new_1" top: "rfcn_bbox" name: "rfcn_bbox" type: "Convolution" convolution_param { num_output: 392 #8*(7^2) cls_num*(score_maps_size^2)(类别数+1)*49*4 kernel_size: 1 pad: 0 weight_filler { type: "gaussian" std: 0.01 } bias_filler { type: "constant" value: 0 } } param { lr_mult: 1.0 } param { lr_mult: 2.0 }}layer { bottom: "rfcn_cls" bottom: "rois" top: "psroipooled_cls_rois" name: "psroipooled_cls_rois" type: "PSROIPooling" psroi_pooling_param { spatial_scale: 0.0625 output_dim: 2 #(类别数+1) 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) } }}layer { name: "bbox_pred_reshape" type: "Reshape" 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。
