Covid19-Repo-Recommender Web app

This web app creates an HTTP API for model inference.

Setup

python3 -m venv covid19-rec-web
source covid19-rec-web/bin/activate
pip install -r requirements.txt

The web app has a different set of requirements than training.

Running the web app

uvicorn main:app --reload

Model Inference API

curl --location --request POST 'http://localhost:8000/predict' \
--header 'Content-Type: application/json' \
--data-raw '{"columns":[0,1],"index":[0],"data":[["Python","Data"]]}'

Deploying to Heroku

heroku create
git push heroku master
heroku buildpacks:set https://github.com/timanovsky/subdir-heroku-buildpack
heroku buildpacks:add heroku/python
heroku config:set PROJECT_PATH=web_app

As web_app is contained with a mono-repo related to the Covid19-Repo-Recommender project, we need to tell Heroku to set the project path to the /web_app directory vs. the default (the root directory). The subdir buildpack and PROJECT_PATH env var are used for this. Setup based on this SO response.
