Trying to run Hailo8 on raspberry pi5 running ubuntu 24.04 LTS

General

I can see all required software and drivers are installed and visible but still getting error, i tried two envs, one with python 3.12 and one with 3.11, both gives same error. without venv i get error with gi not installed even though its installed.

Is there any way I can fix this somehow? We cant change our ubuntu version, or change default python version as it breaks everything.

We need this to work in order to link it to ROS2 and communicate with other nodes. But i tried everything, searched all possible forums and documentation and still getting errors, how would I solve this?

Hey @Jeongmo_Kim ,

It looks like you’re missing the hailo-tappas-core-python-bindings package, which explains why hailo isn’t being found in your virtual environment but is available outside of it. As for the gi issue, this is a known edge case we’ve encountered before, which is exactly why we recommend using a virtual environment.

okay since i found out 4.22 is compatible with python 3.12 i went with those.

But now im getting errors with invalid operation when trying some examples. Why is that?

I fixed it since the hailo example github updated to go with 4.22, now its working fine
