Task-3 -Tweaking Architecture Automatically

ML integration with DevOps - Current need of the industry!!

A time consuming task while training the Machine Learning models is to continuously tweak the Hyper-Parameters to reach our desired Accuracy. It is one of the reasons why most of the ML related projects fail.

This can be resolved upto an extent with MLOPs = ML+ DevOps

In this blog, I'm explaining my MLOPs project which trains and tweaks a CNN model for Cat and Dog prediction from the dataset. My project uses "Jenkins" as an automation-tool and "GitHub" where the developer pushes the code.

Requirements for setting up the project :

1. Git

2. Jenkins
3. Redhat 8 VM
4. Docker

Project :

Creating Environments :

I've created 3 environments (images) in Docker using Dockerfile for running my programs -

1) env1 - This environment is for running any basic program which uses numpy and pandas.

To run the container of env1 -
docker run -it --name con_Basic env1

2) env2 - This environment is for running Old ML programs which use sklearn.
To run the container of env2 -
docker run -it --name con_ML env2

3) env3 - This environment is for runnig DL programs which use keras.
To run the container of env3 -
docker run -it --name con_DL env3

Build Pipeline : This is the build pipeline for my chain of jobs.

Making the model :

I've made a Cat and Dog prediction CNN model which uses the concept of Deep Learning. This is a Binary Classification model.

Layers which I've used are-

-> Convolutional Layer
-> Max Pooling Layer
-> Flattering Layer
-> Dense Layers

I've uploaded the code on my GitHub.

JENKINS JOBS :

I've made 8 jobs for this project-

JOB1 -- Pulling the code from GitHub whenever developer pushes or makes changes in the code.

This job pulls the code from GitHub and copies it to a folder named /Aayushi in Redhat.

JOB2 -- By looking at the program file, Jenkins automatically starts the respective container ( Eg - For CNN code, it should start a container of my "env3")

JOB3 -- Train the model and predict accuracy or metrics.

JOB4 -- This job finds if the accuracy is > 80 % or not.

In this job, we check whether our obtained accuracy matches our desired accuracy and if it matches, an email is sent. If doesn't, the code is tweaked.
