SwinTrack

This is the official repo for SwinTrack.

Update: Our work is accepted by NeurIPS 2022🎇, new model weight & tracking raw results: google drive. arxiv link is updated. Code will be updated soon.

Prepare path.yaml

Copy path.template.yaml as path.yaml and fill in the paths.

LaSOT_PATH: '/path/to/lasot'
LaSOT_Extension_PATH: '/path/to/lasot_ext'
GOT10k_PATH: '/path/to/got10k'
TrackingNet_PATH: '/path/to/trackingnet'
COCO_2017_PATH: '/path/to/coco2017'

Prepare dataset metadata cache (optional)

Download the metadata cache from google drive or baidu pan (passcode: 5dt9), and unzip it in datasets/cache/

Training & Evaluation

Train and evaluate on a single GPU

# Tiny
python main.py SwinTrack Tiny --output_dir /path/to/output --num_workers $num_dataloader_workers

# Base
python main.py SwinTrack Base --output_dir /path/to/output --num_workers $num_dataloader_workers

# Base-384
python main.py SwinTrack Base-384 --output_dir /path/to/output --num_workers $num_dataloader_workers

--output_dir is optional, --num_workers defaults to 4.

note: our code performs evaluation automatically when training is done, output is saved in /path/to/output/test_metrics.

Train and evaluate on multiple GPUs using DDP

# Tiny
python main.py SwinTrack Tiny --distributed_nproc_per_node $num_gpus --distributed_do_spawn_workers --output_dir /path/to/output --num_workers $num_dataloader_workers

Train and evaluate on multiple nodes with multiple GPUs using DDP

# Tiny
python main.py SwinTrack Tiny --master_address $master_address --distributed_node_rank $node_rank distributed_nnodes $num_nodes --distributed_nproc_per_node $num_gpus --distributed_do_spawn_workers --output_dir /path/to/output --num_workers $num_dataloader_workers 

Train and evaluate with run.sh helper script

# Train and evaluate on all GPUs
./run.sh SwinTrack Tiny --output_dir /path/to/output -W $num_dataloader_workers
# Train and evaluate on multiple nodes
NODE_RANK=$NODE_INDEX NUM_NODES=$NUM_NODES MASTER_ADDRESS=$MASTER_ADDRESS DATE_WITH_TIME=$DATE_WITH_TIME ./run.sh SwinTrack Tiny --output_dir /path/to/output --num_workers $num_dataloader_workers 

Ablation study

The ablation study can be done by applying a small patch to the main config file.

Take the ResNet 50 backbone as the example, the rest parameters are the same as the above.

# Train and evaluate with resnet50 backbone
python main.py SwinTrack Tiny --mixin_config resnet.yaml
# or with run.sh
./run.sh SwinTrack Tiny --mixin resnet.yaml

All available config patches are listed in config/SwinTrack/Tiny/mixin.

Train and evaluate with GOT-10k dataset

python main.py SwinTrack Tiny --mixin_config got10k.yaml

Submit $output_dir/test_metrics/got10k/submit/*.zip to the GOT-10k evaluation server to get the result of GOT-10k test split.

Evaluate Existing Model

Download the pretrained model from google drive or baidu pan (passcode: 8hsv), then type:

python main.py SwinTrack Tiny --weight_path /path/to/weigth_file.pth --mixin_config evaluation.yaml --output_dir /path/to/output

Our code can evaluate the model on multiple GPUs in parallel, so all parameters above are also available.
