1、下载 training, validation, test data 和 VOCdevkit（pip install）

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

2、将压缩包解压到目录 VOCdevkit中

tar xvf VOCtrainval_06-Nov-2007.tar
tar xvf VOCtest_06-Nov-2007.tar
tar xvf VOCdevkit_08-Jun-2007.tar

3、目录基本结构如下

$VOCdevkit/                           # development kit
$VOCdevkit/VOCcode/                   # VOC utility code
$VOCdevkit/VOC2007                    # image sets, annotations, etc.
# ... and several other directories ...

4、为 PASCAL VOC 数据集创建一个symlinks，使得多个项目共享

cd $FRCN_ROOT/data
ln -s $VOCdevkit VOCdevkit2007

5、使用同样的方法可以安装 PASCAL VOC 2010 and 2012
