Installation

The application is only working properly on Linux (Ubuntu 20.04). The application requres at least 16GB of RAM on the computer to run explanations, and 64GB of RAM and 24GB GPU Ram for training the models

For installation

Install python 3.8 Install NodeJS

pip install -r requirements.txt npm ci

#start venv linux source venv/bin/activate

Launch Debug have to start both

npm start cd .. python webapp.py runserver

BUILD and run Prod

set debug=false in settings.py

npm run-script build cd .. python webapp.py collectstatic --noinput gunicorn -w 1 -k uvicorn.workers.UvicornWorker --bind=0.0.0.0 --timeout 600 --env DJANGO_SETTINGS_MODULE=webapp_settings webapp_asgi

}

Retraining the models

Before training generate the dataset by running python data_preprocessing.py this will generate on single data/data.csv file used for all pretrainings

The training is configured in the train_*.py files For retraining the models run python train_[model_name].py
