Data Preparation

Please download BraTS 2020 data according to https://www.med.upenn.edu/cbica/brats2020/data.html.
Unzip downloaded data at ./data folder (please create one) and remove all the csv files in the folder, or it will cause errors.

Training

For default training configuration, we use patch-based training pipeline and use Adam optimizer. Deep supervision is utilized to facilitate convergence.

Train and validate on BraTS training set

python train.py --model panet --patch_test --ds

Training on the entire BraTS training set

python train.py --model panet --patch_test --ds --trainset

Breakpoint continuation for training

python train.py --model panet --patch_test --ds -c CKPT

this will load the pretrained weights as well as the status of optimizer and scheduler.

PyTorch-native AMP training

python train.py --model panet --patch_test --ds --mixed

if the training is too slow, please enable CUDNN benchmark by adding --benchmark but it will slightly affects the reproducibility.

Inference

For default inference configuration, we use patch-based pipeline.

python inference.py --model panet --patch_test --validation -c CKPT
