RPi 4.20 release update

General

Hi everyone,
Raspberry Pi has updated their packages with an update for Hailo 4.20 version. The initial release contained a bug, which was brought to our attention by the community—thank you very much!
Raspberry Pi has updated the package, and it should work now.
You can now update using:

sudo apt update
sudo apt full-upgrade
sudo apt install hailo-all
reboot

Update your rpi-examples Git repository if you haven’t done so yet.
If you encounter errors while trying to run the examples, please remove the virtual environment and reinstall:

deactivate
rm -rf venv_hailo_rpi5_examples/
./install.sh

Now, restart the virtual environment and run:

source setup_env.sh 
python basic_pipelines/detection.py

Note: If you performed any manual installations, you may need to remove some packages manually. Hopefully, this won’t be necessary.
Please let us know if you encounter any issues.

Sorry for the bumpy road—hope it’s smooth sailing from here! :blush:

Hi,
The Hailo package on the Pi is integrated as part of the Pi OS release. And got dependencies on other packages. You are not using the default python which comes with the OS. Your python version is 3.8.18 while the default should be 3.11. Hailo python binding are compiled for python 3.11.
I suggest reverting to the original Pi OS defaults.
