Code Usage

1. Dataset preparation

Please download [Guyot dataset] by following the steps under Usage. The structure of the dataset should be as follows:

guyot_data/
└── train/
    └── check/
        └── images
    └── data/
        └── Set02_IMG_3468.pt
    └── img/
        └── images
    └── unet/
        └── images
└── test/
    └── check/
        └── images
    └── data/
        └── Set02_IMG_3468.pt
    └── img/
        └── images
    └── unet/
        └── images
└── val/
    └── check/
        └── images
    └── data/
        └── Set02_IMG_3468.pt
    └── img/
        └── images
    └── unet/
        └── images

2. Training

2.1 Prepare config file

The config file can be found at .configs/tree_2D_use_mst_only1.yaml and .configs/tree_2D_use_unmst_only1.yaml. Make custom changes if necessary.

2.2 Train

For example, the command for training Relationformer is following:

python -m torch.distributed.launch --nproc_per_node=8 train.py --config configs/tree_2D_use_mst_only1.yaml --cuda_visible_device 0 1 2 3 4 5 6 7 

python -m torch.distributed.launch --nproc_per_node=8 train.py --config configs/tree_2D_use_mst_only1.yaml --cuda_visible_device 0 1 2 3 4 5 6 7 --resume trained_weights/check/checkpoint_81_epoch.pkl 

3. Evaluation

Once you have the config file and trained model, run following command to evaluate it on test set:

python valid_smd_guyot_nx.py
