TimeoutError

Thanks for reaching out, Vivek. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
The TimeoutError during process initialization you're encountering with LiveKit agents using RAG based locally and Google for STT, LLM, and TTS is generally related to network, resource, or configuration issues that delay inter-process communication beyond the allowed timeout. Here's a structured approach to troubleshoot this: • Increase Timeout Values: Adjust the 
connect_timeout
, 
read_timeout
, and any API-specific timeouts related to Google STT, TTS to allow more time for the processes to establish connections. • Check Network Connectivity: Ensure your network connection is stable and DNS/firewall settings allow communication with Google APIs. • Resource Utilization: Monitor your system resources (CPU, memory, disk I/O) to ensure there's no resource exhaustion causing delayed responses. • Review Error Handling: Make sure your setup can properly retry or recover from transient errors like timeouts. • Inspect Logs: Check detailed logs for other errors or patterns that may indicate the root cause. Increasing log verbosity during initialization can help. • Update Dependencies: Ensure you have the latest LiveKit agents and related libraries installed to incorporate known fixes. Following these steps should help identify and resolve the cause of the TimeoutError you are seeing.

can you tell me if there is a way in livekit to increase the timeout
t
Hey there! I totally get how tricky process timing can be. LiveKit's got you covered with some super flexible timeout settings. Let me break it down for you: • initialize_timeout: Think of this like giving your process a bit more breathing room during startup. Need extra time to get things rolling? No problem! • close_timeout: This helps ensure your process can shut down smoothly without feeling rushed. • IPC Communication Timeouts: With settings like 
ping_interval
and 
ping_timeout
, you can fine-tune how responsive your processes are. The best part? You can customize these timeouts when you're setting up 
SupervisedProc
or 
ProcPool
to perfectly match what your specific environment needs. Pretty cool, right?
e
where to set initialize_timeout?
t
Hey there! Let me walk you through setting the initialize_timeout parameter when you're working with 
SupervisedProc
or 
ProcPool
in LiveKit. It's super easy! For 
SupervisedProc
, you can do something like this:
Copy code
proc = SupervisedProc(
    initialize_timeout=30.0,  # Timeout in seconds
    close_timeout=10.0,
    memory_warn_mb=512,
    memory_limit_mb=1024,
    ping_interval=1.0,
    ping_timeout=5.0,
    high_ping_threshold=0.5,
    mp_ctx=mp_context,
    loop=event_loop
)
And if you're using 
ProcPool
, the process is just as straightforward:
Copy code
pool = ProcPool(
    initialize_process_fnc=initialize_fn,
    job_entrypoint_fnc=entrypoint_fn,
    num_idle_processes=2,
    initialize_timeout=30.0,  # Timeout in seconds
    close_timeout=10.0,
    inference_executor=None,
    job_executor_type=JobExecutorType.PROCESS,
    mp_ctx=mp_context,
    memory_warn_mb=512,
    memory_limit_mb=1024,
    loop=event_loop
)
Pro tip: Just tweak that 
initialize_timeout
float value (in seconds) to match how long you think your initialization will take. It's totally customizable!
