python==3.8.13
torch==1.12.0
numpy==1.22.3
medpy==0.4.0

tensorboard==2.12.0
tqdm==4.65.0

Please download BraTS2018 training set from here. For preprocessing, please change path (Line35) in preprocess.py, and

cd code/
python preprocess.py

the preprocessed data will be organzied as:

--code
--data
  --brats2018  ##pre-processed data, npy format
    --Brats18_2013_0_1.npy
  --train_list.txt
  --val_list.txt
  --test_list.txt

First, train a teacher model

python pretrain.py --log_dir ../log/teachermodel

For baseline (unimodal in paper),

python train_baseline.py --log_dir ../log/unimodal_modality0 --modality 0

where modality=0,1,2,3 denotes using T1/T2/T1ce/Falir images for training.
For ProtoKD (our method)

python train_protokd.py --modality 0 --log_dir ../log/protokd_modality0

python evaluate.py --model_path ../log/protokd_modality0/model/best_model.pth \
                   --test_modality 0 \
                   --output_path protokd_modality0_outputs

If you want to save visualization results (nii.gz format, you can open it using ITK-Snap or 3D-slicer), please add --save_vis.

python evaluate.py --model_path ../log/protokd_modality0/model/best_model.pth \
                   --test_modality 0 \
                   --output_path protokd_modality0_outputs \
                   --save_vis

We provide models for teacher, baseline T1, protokd T1 in Google Drive.
