Hi,
I'm using NanoPC-T6. I followed the Https://support.axelera.ai/hc/en-us/articles/31859388491794-Bring-up-Voyager-SDK-in-NanoPC-T6 you sent me. However, when I proceed with the test, the test will not proceed with the following error.
https://community.axelera.ai/voyager-sdk-2/axelera-runtime-tar-gz-256?postid=2749#post2749 Someone has had the same issue in this community and I need help if there was a fix.

Hey there ​@dhd6682 !

Could be that the virtual environment isn’t activated? Before running inference, try this:

cd ~/voyager-sdk
source venv/bin/activate

You should see (venv) at the start of your terminal prompt. Then try your inference command again. Let me know if that does it!

Hi Spanner!

I used balena Etcher when I flash os on sd card, and that seems to be the problem. When I flash and install using Raspberry pi imager, the axelera folder was created in the /opt/path that was not created and the required libraries were installed! However, during the test, an error called "inference time out" occurs and stops. First of all, it's solved because it's a short video, but I need help with what to do when I want to test it with a long video. I tried adding --timeout 0 to the command, but it didn't work out.

I just noticed this time that you had already activeted venv! My mistake there.

I wonder if it’s worth testing with YOLOv8s? The current model, YOLOv8l, is pretty big for a power-limited device like the T6. Maybe it’s hitting a thermal or power limit? Could be worth a shot switching models, for diagnostic purposes?
