Preparation

Install SSD (https://github.com/weiliu89/caffe/tree/ssd) following the instructions there, including: (1) Install SSD caffe; (2) Download PASCAL VOC 2007 and 2012 datasets; and (3) Create LMDB file. Make sure you can run it without any errors.
Download the pretrained PeleeNet model. By default, we assume the model is stored in $CAFFE_ROOT/models/
Clone this repository and create a soft link to $CAFFE_ROOT/examples

git clone https://github.com/Robert-JunWang/Pelee.git
ln -sf `pwd`/Pelee $CAFFE_ROOT/examples/pelee

Training & Testing

Train a Pelee model on VOC 07+12:

cd $CAFFE_ROOT
python examples/pelee/train_voc.py

Evaluate the model:

cd $CAFFE_ROOT
python examples/pelee/eval_voc.py

Models

PASCAL VOC 07+12: Download (20.3M)
PASCAL VOC 07+12+coco: Download (20.3M) Download (Model Merged BN with Conv）
MS COCO: Download (21M)
