We're trying to pre-download the turn detector model during our Docker build process but getting an error. According to the docs, we should run python agent.py download-files, but this fails during Docker build. Error during Docker build: Failed to download turn detector model: no job context found, are you running this code inside a job entrypoint? Our agent code: from livekit.agents import cli, WorkerOptions, WorkerType from livekit.plugins.turn_detector.english import EnglishModel async def entrypoint(ctx: JobContext): session = AgentSession( turn_detection=EnglishModel(), # ... other config ) if name == "__main__": cli.run_app( WorkerOptions( entrypoint_fnc=entrypoint, worker_type=WorkerType.ROOM, ), ) Dockerfile: FROM python:3.11-slim WORKDIR /app COPY requirements.txt . RUN pip install --no-cache-dir -r requirements.txt COPY . . RUN python voice_agent.py download-files # This fails CMD ["python", "voice_agent.py"] Question: How can we properly download the turn detector model during Docker build? The download-files command seems to require a job context that doesn't exist during build time.

Thanks for reaching out, Andrew. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
The error occurs because the
download-files
command requires a job context, which isn't available during the Docker build process. To resolve this, you can directly use the plugin's
download_files()
method to pre-download the model files without requiring a job context. Here’s how you can modify your setup: 1. Create a separate script (e.g.,
download_models.py
) with the following content:
Copy code
from livekit.plugins.turn_detector import EOUPlugin

plugin = EOUPlugin()
plugin.download_files()
This script uses the plugin's
download_files()
method to download all necessary model files, including the tokenizer, ONNX model files, and the
languages.json
configuration file. 1. Update your Dockerfile to use this script during the build process:
Copy code
FROM python:3.11-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

# Copy the download script
COPY download_models.py .

# Download models during build
RUN python download_models.py

# Copy your agent code
COPY . .
CMD ["python", "voice_agent.py"]
This approach bypasses the job context requirement and ensures the models are downloaded successfully during the Docker build. Sources: livekit-plugins/livekit-plugins-silero/README.md
