Sorry for not getting to this! I don’t know why it didn’t pop up on my notifications. You could definitely use the PCA 9685 HAT with this system here, just take your time to completely understand how it operates inside Python Programming Language. Once you have that under wraps you’ll be able to port across the code controls into the Hand Recognition Script.
Those errors from your previous post have to do with leftover commands Specific to the Adafruit HAT. If you not using the Adafruit HAT and don’t change the script those errors will continue to pop up.
The computing ooomph that the Raspberry Pi 4 Model B Microprocessor brings to the table is crucial for running the system I have explored in this guide and it won’t run on the Raspberry Pi Pico Microcontroller as is.
Hi. I am also having the same issue. The code runs without any error but does not track my hand.
Running the code on Buster with Python 3.7.3 and Opencv 4.5.5.
Face tracking code worked just fine. So, there is no problem with Picamera. I will really appreciate if someone can help.
Just wanted to provide an update here. The code is working without any problem. Initially, it was not working. However, it started working after a reboot. I think it was a false alarm. Please ignore my previous message. Thanks for this great tutorial.

I have followed all the steps and I still get this, I hope you can help me.
I have a question. I’ve followed the instructions as written, but when I type make -j $(nproc) I run into a snag. Namely, it gets stuck at “[100%] Built target example_tutorial_core_various”
Once it gets to this point, it just stalls out and refuses to continue. I left it on overnight and when I got back, it hadn’t budged in the slightest.
Any help would be appreciated.
Hey Mauricio,
It seems like you are using an incompatible version of the protobuf package. Try running the below command in your terminal:
pip install --upgrade protobuf
Let me know if that helps fix things.
Hey Wesley,
Its possible that you could troubleshoot the process by checking the log files that are produced when you run ‘make’. It might give you a better idea of exactly what has gone wrong there and if something catches your attention with it we can help debug and fix it with you.
Sometimes, the build process can get stuck because of old or corrupted build files. Try cleaning the build directory using the make clean command, and then try building the project again.
Hello, whenever i run the code, i keep getting these error messages. I have tried so many different things but doesn’t seem to work. Its as if it doesn’t recognize mediapipe
It looks like you may have a mix of issues there, the first one I would suggest going through is upgrading the Protobuff package using: pip install --upgrade protobuf
Then running through the mediapipe commands as it seems mediapipe is causing a majority of those errors. You can do that with these commands:
Hope your project turns out super super swell.
