Hello @DJE666

first of all thanks for coming here to share the issue!

Could you please share the complete trace of logs after running

python -m venv .venv
source .venv/bin/activate

pip install --upgrade pip pyaudio six
pip install -r requirements.txt

You mentioned that following these instructions everything works well

You mean that skipping the:

pip install --upgrade pip pyaudio six

works well?

Thanks

Hello Marcpous,

The simplified instructions appear to bypass all the venv setup and package installation requirements.

  • I clone the project to the Uno-Q as directed.

  • A new app appeared in the Uno-Q “My Apps” directory
    image

  • I run the app.

It seems that your instructions are trying to manually setup a new project on the Uno-Q, where the simplified instructions are not.?

However, I want to replicate your work “step-by-step” so that I better understand how to build edge-AI systems for the Uno-Q with multiple models running in a single app.

Regards,

DJE666

Gotcha! thanks for sharing that using Arduino AppLab works well :slight_smile:

Feel free to share all the logs to check why it’s not working on your side!
