Preparation

0. 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.

1. Download the pretrained PeleeNet model. By default, we assume the model is stored in $CAFFE_ROOT/models/

2. 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)
