This guide was originally written for Raspberry Pi OS Buster, with the original Picamera library. When Raspberry Pi released Bullseye, they did so with a promise that eventually there would be a new Picamera2 library that was built on top of the libcamera subsystem. While it was possible to install Picamera2, it was a very involved process that was not friendly to the average user and still highly experimental.
Nearly a year later, they started including Picamera2 with Raspberry Pi OS by default, so it was time for a guide update. At this time, Picamera2 is still in beta, so the installation path that this updated guide uses is designed to make it as easy as possible for you to get a Raspberry Pi up and running with TensorFlow.
The overall installation path will be to using the 64-bit version of the Raspberry Pi Desktop because recent versions of TensorFlow are no longer compiling for the 32-bit OS and the QT OpenGL graphics drivers are installed by default on the Desktop version.
Image Installation
You're going to get started using the latest Raspbian Pi OS Desktop. Start by downloading and installing the latest Raspberry Pi Imager, which makes it super easy to customize all your settings before you even write the image to the SD Card.
Use the imager to burn the operating system image to a Micro SD Card. Raspberry Pi has provided a quick video overview available to watch.
Select the 64-bit Raspberry Pi OS Bullseye Desktop image by going to Raspberry Pi OS (Other) → Raspberry Pi OS (64-bit).
You can customize settings for your Pi by clicking the gear icon in the lower righthand corner after choosing your OS.
Make sure to enable SSH, set a good username and password, set your WiFi credentials, and update the locale settings to your specific needs.
Log In
After properly unmounting ("ejecting") your card for you computer, go ahead and place the microSD card in the Pi and supply power to boot it up. It may take a few minutes before it's available.
On your computer, assuming you left the username as pi and the hostname as raspberrypi.local, SSH into the card using the following:
If you changed your username or hostname settings in the imager, use those instead.
sudo apt update sudo apt upgrade -y sudo apt install -y python3-pip pip3 install --upgrade setuptools
Upgrade Script
We put together a script to easily make sure your Pi is correctly configured and install Blinka. Although Blinka isn't required for this to work, it's nice to have and this script also enables several other interfaces that are required for this project to work. It requires just a few commands to run. Most of it is installing the dependencies.
cd ~ sudo pip3 install --upgrade adafruit-python-shell wget https://raw.githubusercontent.com/adafruit/Raspberry-Pi-Installer-Scripts/master/raspi-blinka.py sudo python3 raspi-blinka.py
If your system default Python is Python 2 (which usually is no longer the case with the recent versions of Raspberry Pi OS), it will ask to confirm that you want to proceed. Choose yes.
