In this project, we use tools like direnv, nix-shell, and environment profiles to facilitate seamless integration with AWS services. These tools will help you manage environment variables and dependencies while making the process more streamlined.
2. Choosing the Development Path
   Depending on your personal preferences and the tools you’re most comfortable with, you can choose either the Python Development Path or the Clojure Development Path. Both paths will guide you through the project, but with different approaches and tools. Python is widely used in AI/ML, while Clojure introduces a functional programming paradigm that might appeal to those interested in exploring alternative approaches.
3. Setting Up the Development Environment
   This step involves configuring the virtual environments, dependency management tools, and ensuring that the necessary AWS services are accessible. The Python environment is set up using Poetry, while the Clojure path uses Leiningen for dependency management.
4. Integrating AWS Services
   To start working with AWS services, you’ll need to configure AWS access, both for local development and for cloud-based development. Tools like the AWS CLI and boto3 (Python SDK) or other Clojure libraries are used to connect to AWS services like S3, SageMaker, and Lambda. Understanding how to authenticate with AWS and simulate services locally will be essential as you progress through the project.

Environment Setup

The first task in the development workflow is to set up the environment on your machine. This involves preparing the necessary tools and ensuring that your development environment is properly configured for local and cloud-based development.

Enabling direnv

direnv is a tool that manages environment variables based on the current directory. It automatically loads and unloads environment variables when you enter and exit a directory. This can be particularly useful when working on projects that require specific configurations or credentials.

To enable direnv:

1. Install direnv using your package manager or from the official website.
2. Hook direnv into your shell (e.g., add eval “$(direnv hook bash)” to your .bashrc or .zshrc).
3. In your project directory, create an .envrc file that defines your environment variables, such as AWS credentials or other settings specific to your project.
4. Run direnv to allow it to load your environment variables.

Entering the nix-shell

The nix-shell is used for creating isolated development environments, especially when working with dependencies that need to be locked to specific versions. This ensures that you have a consistent development setup and that your environment will not conflict with other projects.

1. To start the development environment, run nix-shell in your terminal. This command loads the shell environment defined for the project, setting up necessary dependencies.
2. Inside the nix-shell, you can access a fully configured environment with all the tools and dependencies ready for development.

Choosing Your Development Path

Once the environment is set up, you can choose between the Python Development Path and the Clojure Development Path. These paths allow you to approach the project from different perspectives and provide flexibility in how you engage with the materials.

Python Development Path

If you are comfortable with Python or if you want to work with popular AI/ML libraries such as TensorFlow, PyTorch, or scikit-learn, the Python Development Path is ideal. This path makes use of Poetry for dependency management and includes Python-based tools for interacting with AWS services.

Poetry for Dependency Management

Poetry simplifies the management of Python dependencies by automatically creating virtual environments and handling package installations. To start the Poetry environment:

1. Run poetry install to install all the dependencies specified in the pyproject.Toml file.
2. Activate the Poetry shell by running poetry shell. This will activate the virtual environment where you can install additional dependencies or run Python scripts.

AWS Integration with Python

Python is commonly used in AI/ML development, and AWS provides a Python SDK called boto3 for interacting with AWS services. You will be using boto3 to communicate with services such as S3, SageMaker, and Lambda. For example, to list S3 buckets, you can write a Python script like this:

import boto3

 

def list_s3_buckets():

    s3 = boto3.client(‘s3’)

    response = s3.list_buckets()

    return [bucket[‘Name’] for bucket in response[‘Buckets’]]

 

print(list_s3_buckets())

 

This code will connect to the S3 service and print a list of all available S3 buckets in your AWS account.

Clojure Development Path

For learners interested in exploring functional programming or who wish to use Clojure for AI/ML workflows, the Clojure Development Path provides an alternative approach. This path uses Leiningen for managing dependencies and focuses on the REPL-driven development model.

Leiningen for Dependency Management

Leiningen is a build automation tool for Clojure that also handles dependency management. To set up Leiningen:

1. Install Leiningen following the instructions on its official website.
2. Once installed, you can create a new Clojure project using lein new.
3. Add necessary dependencies to the project.CLJ file for AWS integration and other libraries you may need.
4. Run lein deps to fetch the dependencies and set up your environment.

REPL-Driven Development in Clojure

Clojure’s REPL (Read-Eval-Print Loop) provides an interactive environment for development. You can test small code snippets, experiment with data structures, and quickly see results without needing to write full scripts.

For instance, if you’re working with Clojure and want to interact with AWS services, you would open a REPL session and load the relevant namespaces. For example:

(require ‘[aif-c01.d1-fundamentals.basics :as d1])

(d1/explain-ai-term :ml)

(d1/list-ml-types)

 

This allows you to interactively explore and manipulate data, making it a powerful tool for learning and experimenting with new ideas in machine learning.

Setting Up LocalStack

To use LocalStack in this project:

1. Install Docker: LocalStack relies on Docker to run AWS service simulations.
2. Switch to the LocalStack profile: Set up the environment to use LocalStack by running make switch-profile-lcl.
3. Start LocalStack: Launch LocalStack using make localstack-up. This will spin up the necessary AWS services locally, such as S3, Lambda, SageMaker, and more.
4. Run the REPL: Once LocalStack is running, use make run to start the REPL and begin interacting with the simulated AWS services.

Example Workflow with LocalStack

You can test out AWS services such as S3 by creating buckets, uploading files, and performing other operations—all locally. For instance, to create a new S3 bucket locally, you would run:

aws s3 mb s3://my-bucket-name –endpoint-url=http://localhost:4566

 

This command will create a new bucket on LocalStack’s simulated S3 service. You can then interact with this bucket as if you were using the real AWS S3 service.

Cloud Development

In addition to working locally with LocalStack, the project also supports cloud-based development using AWS CLI to interact with live AWS resources. You can switch to the AWS development profile and use AWS services in a real cloud environment. For example, to check your AWS identity, you can run:

aws sts get-caller-identity

 

This command will verify your access to AWS and return details about the currently authenticated user.

By understanding and configuring your development environment, you can maximize your learning experience as you prepare for the AWS Certified AI Practitioner (AIF-C01) and AWS Certified Machine Learning Engineer – Associate (MLA-C01) exams.
