AttributeError: 'WebRTCVADAnalyzer' object has no attribute '_vad_frames_num_bytes' on Ubuntu 22.04 / Python 3.10.2

Hello,

I'm encountering an error when running a voice agent using Pipecat with the Daily.co transport on Ubuntu 22.04 and Python 3.10.2. Error message:

AttributeError: 'WebRTCVADAnalyzer' object has no attribute '_vad_frames_num_bytes'

🧪 Context

OS: Ubuntu 22.04

Python: 3.10.2

Pipecat AI version: 0.0.62

Usage: I'm trying to run a French-speaking voice assistant using Pipecat with the DailyTransport, TTS via Cartersia, and a LLM backend using Ollama (LLaMA 3.2:3b).

Has anyone else encountered this error with WebRTCVADAnalyzer? Any ideas or workarounds would be greatly appreciated.

Hi! I have not seen this reported elsewhere. Can you try running the simple chatbot example to see if you get it there?

@Razziat are you still impacted? I'd recommend using SileroVADAnalyzer as it has superior performance.
