Thanks, will try. Looking for a hand tracking solution that might work on Jetson Nano (or rpi4) or other SBC. Would hire a consultant gladly. For user acceptance, I really need 25 fps or better. ---

How many frames per second were you able to get with your Raspberry Pi hand tracker? Suitable for control of cursor movement or a bit too slow? ---

Hi @Harry272782 - are you using the correct OS version as recommended during the guide? That might be a good point to start if not. Historically, computer vision and ML projects have been tricky on Pi, and it may be that certain packages have been updated and become incompatible. It might be worth seeking out the latest guidance from the maintainer of the `mediapipe` package.
