I downgraded to kernel 6.12.20 following this steps and it worked
Hi @AbnerDC , our team is investigating the problem. Will keep you posted
@AbnerDC , can you share with us the output of the following command on the system which fails with an error:
sudo dmesg | grep hailo
Sure:

With the latest R.PI image, I followed the install instructions in github and have some feedback to help get the jupyter examples to work OK.
- Error 1 - 014_person_reid
- I had to execute the following command to install âslkearnâ
pip install -U scikit-learn
- I had to execute the following command to install âslkearnâ
- Error 2 - General error message
- qt.qpa.plugin: Could not find the Qt platform plugin âwaylandâ
- Error 3 - Overall problem
- Raspberry Pi hangs after executing examples within the environment. The only way to fix was to reboot
Hopefully this is enough info?
Hi @AbnerDC
We confirmed that downgrading to kernel 6.12.20 indeed fixes the problem. We tracked down this error to scatter-gather list creation in the kernel driver, which for some reason intermittently fails on 6.12.25. So the workaround is to switch to kernel 6.12.20 until Hailo guys or RPi team will fix it.

Hi @Curlywurly
Thanks for bringing these to our notice.
Error 1: We will fix the requirements.txt so that scikit-learn is included
Error 3: Can you find your kernel version? Lately, people have complained that kernel 6.12.25 is causing crashes. Please let us know if your issue is unrelated.
Error 2: Is it a warning or an error that is crashing the program?
hello! i want to know if these models that you are using are available on the .hef format (the scrfd and the other)
Hi @constanza_bo
Welcome to the Hailo community. Yes, the models are available in hef format. You can see hailo-ai/hailo_model_zoo: The Hailo Model Zoo includes pre-trained models and a full building and evaluation environment.
