sparv-backend

There are several options for running the Sparv backend:

1. in a Docker environment
2. with gunicorn
3. with waitress (mostly for testing purposes)

Installation

• Create config.py and adapt variables:

  cp app/config_default.py app/config.py

• Create python virtual environment for backend (not needed when using Docker)

  python3 -m venv venv
  source venv/bin/activate
  pip install --upgrade pip
  pip install -r requirements.txt
  deactivate

Installation of additional components

• Clone catapult repo and build catalaunch:

  git clone https://github.com/spraakbanken/sparv-catapult.git
  make -C sparv-catapult

• Create venv for catapult:

  python3 -m venv sparv-catapult/venv
  source sparv-catapult/venv/bin/activate
  pip install --upgrade pip
  pip install -r sparv-catapult/requirements.txt
  deactivate

• Clone Sparv pipeline repo:

  mkdir -p "data/pipeline"
  git clone https://github.com/spraakbanken/sparv-pipeline.git data

• Follow the Sparv pipeline installation instructions.

Running the Sparv backend

1. With Docker: [add commands]

2. With gunicorn (you may want to adapt the settings in gunicorn_config.py):

   PATH_TO_BACKEND=`pwd`
   $PATH_TO_BACKEND/app/venv/bin/gunicorn --chdir $PATH_TO_BACKEND/app -c $PATH_TO_BACKEND/app/gunicorn_config.py app

3. With waitress (run with python3):

   PATH_TO_BACKEND=`pwd`
   python $PATH_TO_BACKEND/app.py
