How to setup the environment

On a Local Machine

Create and activate the conda environment with python 3.8.2

conda create --name <env-name> python=3.8.2
conda activate <env-name>

Install the libraries listed in requirements.txt

pip install -r requirements.txt

Run the code

cd src
python run.py

With Docker

The repo also contains Dockerfile to run the code

docker build -t <image_name>:<tag> .
docker run -t --name <container-name> <image_name> <experiment-to-run>

Example:

docker build -t daema:latest .
docker run -t --name daema_container daema:latest python run.py

Test your installation

You can test your installation by running

PYTHONPATH=src/ pytest tests

• Full loss: python run.py --daema_loss_type full
• No art. miss.: python run.py --daema_pre_drop 0

How to add a dataset

To test the code on a local dataset:

• put the dataset in files/data/<name>.csv;
• update the src/pipeline/datasets/DATASETS variable to add your dataset;
• run the tests;
• use the --datasets argument to select it for the experiments (e.g. python run.py --datasets <name>).

How to add a model

To test the code on a custom model:

• implement the model following the expected interface (see src/models/baseline_imputations/Identity for the basic structure);
• update the src/models/__init__/MODELS variable to add your model;
• run the tests;
• use the --model argument to select it for the experiments (e.g. python run.py --model <Name>).
