Prerequisites

  • Linux or similar environment
  • Python 3.7
  • Pytorch 0.4.1
  • NVIDIA GPU + CUDA CuDNN

Getting Started

Installation

  • Clone this repo:

    git clone https://github.com/fei-hdu/NAS-Lung
cd NAS-Lung

  • Install PyTorch 0.4+ and torchvision from Pytorch and other dependencies (e.g., visdom and dominate). You can install all the dependencies by

    pip install -r requirments.txt

  • Download Dataset LIDC-IDRI

Neural Architecture Search

python search_main.py --train_data_path {train_data_path}  --test_data_path {test_data_path} --save_module_path {save_module_path}

Train/Test

  • Train a model

    sh run_training.sh

  • Test a model

    python test.py --test_data_path {test_data_path} --preprocess_path {preprocess_path} --model_path {model_path}
