Trained and evaluated on NVIDIA GeForce RTX 3090 with python 3.8.5.

1. Set up a python environment

conda create -n sleepyco python=3.8.5
conda activate sleepyco

2. Install PyTorch with compatible version to your develop env from PyTorch official website.

3. Install remaining libraries using the following command.

pip install -r requirements.txt

1. Download Sleep-EDF-201X dataset via following command. (X will be 3 or 8)

cd ./dset/Sleep-EDF-201X
python download_sleep-edf-201X.py

2. Check the directory structure as follows

./dset/
└── Sleep-EDF-201X/
    └── edf/
        ├── SC4001E0-PSG.edf
        ├── SC4001EC-Hypnogram.edf
        ├── SC4002E0-PSG.edf
        ├── SC4002EC-Hypnogram.edf
        ├── ...

3. Preprocess .edf files into .npz.

python prepare_sleep-edf-201X.py

4. Check the directory structure as follows

./dset/
└── Sleep-EDF-201X/
    ├── edf/
    │   ├── SC4001E0-PSG.edf
    │   ├── SC4001EC-Hypnogram.edf
    │   ├── SC4002E0-PSG.edf
    │   ├── SC4002EC-Hypnogram.edf
    │   ├── ...
    │
    └── npz/
        ├── SC4001E0-PSG.npz

python train_crl.py --config configs/SleePyCo-Transformer_SL-01_numScales-1_{DATASET_NAME}_pretrain.json --gpu $GPU_IDs

When one GeForce RTX 3090 GPU is used, it may requires 22.3 GB of GPU memory.

python train_mtcl.py --config configs/SleePyCo-Transformer_SL-10_numScales-3_{DATASET_NAME}_freezefinetune.json --gpu $GPU_IDs

When two GeForce RTX 3090 GPU is used, it may requires 16.7 GB of GPU memory each.

If you use PyTorch $\geq$ 2.0.0, it may requires only 5.4 GB of GPU memory.

python train_mtcl.py --config configs/SleePyCo-Transformer_SL-10_numScales-3_{DATASET_NAME}_scratch.json --gpu $GPU_IDs

1. Download and extract checkpoint using python download_checkpoints.py.

• You can download all checkpoints using following command:

  cd checkpoints
  python download_checkpoints.py
  

• You can also select checkpoints as follows:

  cd checkpoints
  python download_checkpoints.py --datasets 'Sleep-EDF-2013' 'Sleep-EDF-2018'
  

2. Evaluate the dataset using the following command.

python test.py --config configs/SleePyCo-Transformer_SL-10_numScales-3_{DATASET_NAME}_freezefinetune.json --gpu $GPU_IDs
