Celery Distributed Task Queue with FastAPI for Machine Learning

This sample app demonstrates how to implement Celery distributed task queues on top of RabbitMQ broker for Machine Learning model training and data processing. We are using TensorFlow in this example to train the model. API request comes through FastAPI and it is being processed asynchronously by Celery. There is a separate API endpoint to check task status. Multiple requests can be initiated and processed at the same time in parallel. Celery tasks can be monitored using Flower monitoring tool.

RabbitMQ RPC with FastAPI

I explain sample app with FastAPI endpoint. RabbitMQ is used as a postman to deliver and return message between endpoint API and backend. Backend code could run on different microservice. Multiple backends can be started for scalability.

TensorFlow.js Blueprint App Step by Step

I describe how to prepare data that comes from API into TensorFlow.js Dataset structure, how to shuffle, normalize, one-hot-encode, and batch the data. Next, I go on model training and explain why fitDataset is recommended way to train a neural network in TensorFlow.js. At last, I show how to do inference and print the results. This app is built with React, but the same code can be reused with any JS toolkit/framework.

Rabbit MQ with Docker for Microservices

Rabbit MQ message broker helps to implement event-driven architecture for microservices. Instead of tight coupling multiple services, we can send and subscribe to events. In this video, I explain how to dockerize Rabbit MQ and provide a simple, but complete example of communication through Rabbit MQ.

React and TensorFlow.js

I explain how to create React app with Yarn and how to integrate TensorFlow.js into that app. A simple model is trained with TensorFlow.js to give you a good starting point. I also show how to run the predict function and read the output.

ML Microservice with Python and gRPC

I explain how to implement microservice in Python for Machine Learning code. In this example, data processing is done with Pandas, Numpy, and Scikit-Learn libraries. Communication is implemented through gRPC, I explain how to send Numpy array through gRPC.
