Note:

• Speed are tested on a NVIDIA RTX 2080.
• -box reports an axis-aligned bounding box from the box branch.
• -LD means training with large dataset (ytb-bb+ytb-vos+vid+coco+det).

Training

Training Data

• Download the Youtube-VOS, COCO, ImageNet-DET, and ImageNet-VID.
• Preprocess each datasets according the readme files.

Download the pre-trained model (174 MB)

(This model was trained on the ImageNet-1k Dataset)

cd $SiamMask/experiments
wget http://www.robots.ox.ac.uk/~qwang/resnet.model
ls | grep siam | xargs -I {} cp resnet.model {}

Training SiamMask base model

• Setup your environment
• From the experiment directory, run

cd $SiamMask/experiments/siammask_base/
bash run.sh

• Training takes about 10 hours in our 4 Tesla V100 GPUs.
• If you experience out-of-memory errors, you can reduce the batch size in run.sh.
• You can view progress on Tensorboard (logs are at <experiment_dir>/logs/)
• After training, you can test checkpoints on VOT dataset.

bash test_all.sh -s 1 -e 20 -d VOT2018 -g 4  # test all snapshots with 4 GPUs

• Select best model for hyperparametric search.

#bash test_all.sh -m [best_test_model] -d VOT2018 -n [thread_num] -g [gpu_num] # 8 threads with 4 GPUS
bash test_all.sh -m snapshot/checkpoint_e12.pth -d VOT2018 -n 8 -g 4 # 8 threads with 4 GPUS

Training SiamMask model with the Refine module

• Setup your environment
• In the experiment file, train with the best SiamMask base model

cd $SiamMask/experiments/siammask_sharp
bash run.sh <best_base_model>
bash run.sh checkpoint_e12.pth

• You can view progress on Tensorboard (logs are at <experiment_dir>/logs/)
• After training, you can test checkpoints on VOT dataset

bash test_all.sh -s 1 -e 20 -d VOT2018 -g 4

Training SiamRPN++ model (unofficial)

• Setup your environment
• From the experiment directory, run

cd $SiamMask/experiments/siamrpn_resnet
bash run.sh

• You can view progress on Tensorboard (logs are at <experiment_dir>/logs/)
• After training, you can test checkpoints on VOT dataset

bash test_all.sh -h
bash test_all.sh -s 1 -e 20 -d VOT2018 -g 4
