Deploying NLP Models in Production using MLOps

This repository contains code for the O'Reilly Live Online Training for Deploying NLP Models in Production using MLOps

This training provides an overview to the end-to-end Natural Language Processing pipeline including the initial model training, production deployment and serving, model evaluation, and continuous training cycles to combat model/data drift.

We look at various tools including PyTorch serve and MLflow to manage model versions and deploy them in a production infrastructure. We also see several code examples throughout the training around a semantic search use-case using BERT to help solidify the theoretical concepts being introduced.

Cleaning Data

Installation

1. Make sure you have FastAPI and uvicorn installed (it is in the requirements.txt)

Running the App

1. From the deploy directory, run uvicorn api:app --reload to start your local flask app
2. Test the app by going to http://localhost:8000/docs

Using Docker

In the deploy directory:

to build: docker build . --tag fastapi-demo:1

You may need to run with a specified paltform if you use a macbook with the M1 chip like I do: docker build . --tag fastapi-demo:1 --platform linux/amd64

to run: docker run -p 80:8000 --platform linux/amd64 fastapi-demo:1

navigate to http://localhost/docs

To deploy docker image to Heroku
