Quick project for running Edge Impulse on balena, specifically providing an example of accessing the Pi V2 camera using libcamera on Bullseye.
This project also installs the files required to run the Edge Impulse Python SDK.
You need to have a balena account and an Edge Impulse account with a working project.
Add the following device configuration variable:
BALENA_HOST_CONFIG_camera_auto_detect = 1
(You may also need to increase the device GPU memory to at least 32 MB.)
Push this project to your fleet (Raspberry Pi 4 only) and then SSH into the "ei" container.
Run edge-impulse-linux and follow the prompts.

The Edge Impulse Linux software seems to require a Pulseaudio server, which is why we are using the audio block.
