Tookit need Python 3, pytorch 1.1.0

Prepare SegTHOR dataset

reading preprocessing.ipynb in details

the source data download from https://ent.normandie-univ.fr/filex/get?k=oZgYIeT5lnbxhtHZ2u8
or download from my Baidu Netdisk https://pan.baidu.com/s/1dQHYKIkUd5qCXIvdxSijNg; password: i41q
The data path organized like:
../data/data_source/Patient_01/GT.nii
../data/data_source/Patient_01/Patient_01.nii
Then, using preprocessing.ipynb to process the SegTHOR dataset for 4-fold cross-validation

Network training

See main.py parser.argument in details

A test run is like this
python3 main.py -b 16 --gpu 0,1,2,3 --model_name ResUNet101 --save_dir SavePath/SM --lr 0.01 --if_dependent 0 --if_closs 0

Important parameters:

• model_name -> indicate which encoder network is used. Please check models/model_loader.py in details.
• if_closs -> if using the classification loss (MTL). if_closs=0, MTL is not deployed.
• if_dependent -> if using the WMCE loss function. if_dependent=0, binary relevance with BCE loss functions is used.

Network testing

See prediction.ipynb in details
