Training and evaluation on OpenKBP

Data Preparation

Download OpenKBP challenge repository, and copy the data folder "provided-data" into this repository. You can run data preprocess step with the following command:

cd DoseDiff-main

# Convert csv data into nii format
python csv2nii.py

# Generate distance map and missing ROI
python PSDM_OpenKBP.py

# Convert 3D into 2D for training
python NII_to_npy.py

Model training

CUDA_VISIBLE_DEVICES=0,1 python -m torch.distributed.launch --nproc_per_node=2 --master_port=9999 train.py --gpu 0,1 --bs 16 --T 1000 --epoch 1600

Model evaluation

CUDA_VISIBLE_DEVICES=0 python pred.py --gpu 0 --bs 64 --model_path trained_models/T1000_bs32_epoch1600/model_best_mae.pth --TTA 1 --T 1000 --ddim 8
