Installing useful libraries

git clone https://github.com/NVIDIA/apex && cd apex && pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./

pip install efficientnet_pytorch
pip install pretrainedmodels

Command

main.py:

python main.py


 --train True (default:False)

 --post_train True (default:False)
 
 --test True (default:False)

 --foldn 0 (default:0, 0,1,2,3,4)

 --tta 5 (default:5, integer above 0)

 --make_fold True (default:False, 5 folds with seed=10)

windowing.py

python windowing.py

 --mode train (default='test', 'train' or 'test')
 --input /input/csv_dicom/ (directory in which there are csv and dicom)
 --output /../../ (to which save png files)
 --p 4 (default:4,integer depending on your cpu)

analysis

• confusion matrix

• Receiver Operating Characteristic

• Stacking
