Optimizing Raspberry Pi for AI: A Guide to Avoid Common Pitfalls

What is a Raspberry Pi?

Before diving into the tips, let’s briefly define what a Raspberry Pi is.

Raspberry Pi is the name of a series of single-board computers made by the Raspberry Pi Foundation, a UK charity that aims to educate people in computing and create easier access to computing education. All over the world, people use the Raspberry Pi to learn programming skills, build hardware projects, do home automation, implement Kubernetes clusters and Edge computing, and even use them in industrial applications.

The Raspberry Pi is a computer that runs Linux, but it also provides a set of GPIO (general purpose input/output) pins, allowing you to control electronic components for physical computing and explore the Internet of Things (IoT).

Working on a Project with Raspberry Pi and AI Models? Here’s What You Need to Know

If you’re working on a project that requires using a Raspberry Pi and AI models, it’s important to follow some guidelines to save time and avoid unnecessary searching. Based on my experience, I’m sharing some tips that I’ve found helpful ,and I hope you will too!

Raspberry Pi Models Comparison

In my experience, I’ve used a few different models of the Raspberry Pi. Here’s a comparison between them:

• Raspberry Pi Zero 2 W

  • CPU: 1GHz single-core

  • RAM: 512MB

• Raspberry Pi 3B+

  • CPU: Broadcom BCM2837B0, Quad-core Cortex-A53 (ARMv8) 64-bit SoC @ 1.4GHz

  • RAM: 1GB LPDDR2 SDRAM

• Raspberry Pi 4

  • CPU: Broadcom BCM2711, Quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz

  • RAM: 1GB, 2GB, or 4GB LPDDR4-3200 SDRAM (depending on the model)

Recommended Raspberry Pi Version

For the best performance and library compatibility, I strongly recommend using the 4B version, 4GB RAM at a minimum. It offers stable data processing and better results compared to the other versions, so opt for the 4B or a higher model.

Operating System

As you know, you’ll need to install an operating system on your Raspberry Pi to get the best human-machine interface experience. There are several tools available for setting up the OS, including:

• Raspberry Pi Imager :The official, standard imaging utility from the Pi Foundation

• Etcher :An open-source flashing app with a simple interface

• Win32 Disk Imager : Lightweight image writing tool for Windows

• RPi-sd card Builder : Automated imaging for multiple Pi projects

• ApplePi Baker :Made specifically for Mac users

Among these options, I’ve found that Raspberry Pi Imager is the best choice for writing images and ensuring a reliable OS installation. For optimal performance with Python, I recommend using Raspberry Pi OS, which is a Linux distribution specifically designed for the Raspberry Pi.

When it comes to AI Python libraries, the “Raspberry Pi OS Bullseye 64-bit” version offers the best compatibility and flexibility, this version comes with Python 3.9.

this setup has provided the best compatibility and flexibility for AI Python libraries than the newer “Bookworm” version. If you’re focusing on AI development, Bullseye is the way to go.

Install Raspberry Pi OS using Raspberry Pi Imager

Installing Libraries

After installing the OS, you might find yourself searching for the best versions of libraries like OpenCV, h5py, NumPy, and TensorFlow. Most libraries are easy to install and will work without any issues, but TensorFlow can be tricky. I tested many versions without success until I found the one that works with my OS: TensorFlow 2.10. This version is the most compatible, so I highly recommend it.

sudo apt install tensorflow==2.10.0

SD Card Storage

You should use at least a 16 GB SD card for your work. The OS itself doesn’t take up much space,around 3 GB maximum,but once you start installing libraries, you’ll need more space. The OS also requires regular updates.

sudo apt update 
sudo apt upgrade

Final Tip: Where to Buy Your Raspberry Pi

Finally, I recommend buying your Raspberry Pi directly from the official store in the UK to get it at a lower price.
