Installation

Please see INSTALL.md.

Testing

Testing on Cityscapes

1. Download the pretrained model here and put it to $ROOT/data/model/rcnn_snake/long_rcnn/197.pth.
2. Test:

   # use coco evaluator
   python run.py --type evaluate --cfg_file configs/city_rcnn_snake.yaml
   # use the cityscapes official evaluator
   python run.py --type evaluate --cfg_file configs/city_rcnn_snake.yaml test.dataset CityscapesVal
   

3. Speed:

   python run.py --type network --cfg_file configs/city_rcnn_snake.yaml
   

Testing on Kitti

1. Download the pretrained model here and put it to $ROOT/data/model/snake/kins/149.pth.
2. Test:

   python run.py --type evaluate --cfg_file configs/kins_snake.yaml test.dataset KinsVal
   

3. Speed:

   python run.py --type network --cfg_file configs/kins_snake.yaml test.dataset KinsVal
   

Testing on Sbd

1. Download the pretrained model here and put it to $ROOT/data/model/snake/sbd/149.pth.
2. Test:

   python run.py --type evaluate --cfg_file configs/sbd_snake.yaml test.dataset SbdVal
   

3. Speed:

   python run.py --type network --cfg_file configs/sbd_snake.yaml test.dataset SbdVal
   

Visualization

Visualization on Cityscapes

1. Download the pretrained model here and put it to $ROOT/data/model/rcnn_snake/long_rcnn/197.pth.
2. Visualize:

   # Visualize Cityscapes test set
   python run.py --type visualize --cfg_file configs/city_rcnn_snake.yaml test.dataset CityscapesTest ct_score 0.3
   # Visualize Cityscapes val set
   python run.py --type visualize --cfg_file configs/city_rcnn_snake.yaml test.dataset CityscapesVal ct_score 0.3
   

If setup correctly, the output will look like

Visualization on Kitti

1. Download the pretrained model here and put it to $ROOT/data/model/snake/kins/149.pth.
2. Visualize:

   python run.py --type visualize --cfg_file configs/kins_snake.yaml test.dataset KinsVal ct_score 0.3
   

Visualization on Sbd

1. Download the pretrained model here and put it to $ROOT/data/model/snake/sbd/149.pth.
2. Visualize:

   python run.py --type visualize --cfg_file configs/sbd_snake.yaml test.dataset SbdVal ct_score 0.3
   

Demo

We support demo for image and image folder using python run.py --type demo --cfg_file /path/to/yaml_file demo_path /path/to/image ct_score 0.3.

For example:

python run.py --type demo --cfg_file configs/sbd_snake.yaml demo_path demo_images ct_score 0.3
# or
python run.py --type demo --cfg_file configs/sbd_snake.yaml demo_path demo_images/2009_000871.jpg ct_score 0.3

If setup correctly, the output will look like

Training

The training parameters can be found in project_structure.md.

Training on Cityscapes

Two-stage training:

1. Train the detector:

   python train_net.py --cfg_file configs/city_ct_rcnn.yaml model rcnn_det
   

2. Train the detector and snake together:

   python train_net.py --cfg_file configs/city_rcnn_snake.yaml model rcnn_snake det_model rcnn_det
   

Training on Kins

python train_net.py --cfg_file configs/kins_snake.yaml model kins_snake

Training on Sbd

python train_net.py --cfg_file configs/sbd_snake.yaml model sbd_snake

Tensorboard

We provide tensorboard for seeing the training status:

# for the rcnn_snake task
tensorboard --logdir data/record/rcnn_snake
# for the snake task
tensorboard --logdir data/record/snake

If setup correctly, the output will look like
