why an i seeing unable to load cuda in y livekit agent logs

Thanks for reaching out, Nick. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

no these errors are in my livekit logs:

Failed to load CUDA modules. maybe the NVIDIA driver is not installed?
Failed to initialize CUDA context.
Failed to open VA display. Maybe the AMD video driver or libva-dev/libdrm-dev is not installed?
Failed to open VAAPI display.

It looks like the errors in your LiveKit logs are related to GPU drivers and video acceleration libraries. Don’t worry, I’m here to help you work through them step by step: • CUDA Module Errors: First, please make sure your NVIDIA driver is installed and up to date. Also, check that

libcuda.so.1

(on Linux) or

nvcuda.dll

(on Windows) is available. The driver version should be 11.0 or higher to work smoothly. • VA/VAAPI Display Errors (Linux): You’ll want to install the necessary libraries like

libva-dev

and

libdrm-dev

. Also, confirm that your AMD or Intel GPU driver is installed and that your user has access to the render device, such as

/dev/dri/renderD128

. • VAAPI Display Errors (Windows): Double-check that the correct GPU adapter is selected. You can use

--device help

to see the available adapters. Also, make sure

DXCore.DLL

is present and up to date. • General Steps: It’s helpful to review your logs for specific failure points. Running

livekit-cli debug

can provide useful diagnostics. Lastly, please verify that your hardware supports the required video acceleration features. If you have any questions or need a hand with any of these steps, just let me know—I’m happy to assist!

this is a non gpu machine and is only running agent py scripts, are there any livekit services we might be using that could result in missing cuda errors

I understand how frustrating CUDA-related errors can be when running agent Python scripts on non-GPU machines. These errors usually happen because the scripts or services try to initialize GPU acceleration by default. To help you avoid this, you can explicitly set the device policy to CPU by adding

--policy.device=cpu

to your script's configuration or command-line arguments. If you're using a Mac, you can instead use

--policy.device=mps

. Please feel free to reach out if you need any more help with this setup—I'm here to support you! Sources: lerobot/scripts/display_sys_info.py
