Hi folks. I'm trying to deploy a VoicePipelineAgent on Railway.

This agents works locally, and was working on Railway several weeks ago as well on the initial deployment. However, I needed to create a fresh instance and now I'm getting the "Unrecognized model in livekit/turn-detector" issue below (I haven't changed requirements or the dockerfile in the meanwhile). I'm on Windows 10 for local dev.

File "/app/agent_bab.py", line 786, in <module>
cli.run_app(
raise ValueError(
File "/usr/local/lib/python3.12/site-packages/livekit/agents/cli/cli.py", line 184, in download_files plugin.download_files()
File "/usr/local/lib/python3.12/site packages/livekit/plugins/turn_detector/__init__.py", line 34, in download_files
AutoTokenizer.from_pretrained(HG_MODEL, revision=MODEL_REVISION)
File "/usr/local/lib/python3.12/site-packages/transformers/models/auto/tokenization_auto.py", line 966, in from_pretrained
config = AutoConfig.from_pretrained(
ValueError: Unrecognized model in livekit/turn-detector. Should have a model_type key in its config.json, or contain one of the following strings in its name: albert, align, altclip,...

... File "/usr/local/lib/python3.12/site-packages/transformers/models/auto/configuration_auto.py", line 1151, in from_pretrained

This is my dockerfile:

ARG PYTHON_VERSION=3.12.9 FROM python:${PYTHON_VERSION}-slim as base # Prevents Python from writing pyc files. ENV PYTHONDONTWRITEBYTECODE=1 # Keeps Python from buffering stdout and stderr to avoid situations where # the application crashes without emitting any logs due to buffering. ENV PYTHONUNBUFFERED=1 WORKDIR /app # Create a non-privileged user that the app will run under. ARG UID=10001 RUN adduser \ --disabled-password \ --gecos "" \ --home "/nonexistent" \ --shell "/sbin/nologin" \ --no-create-home \ --uid "${UID}" \ appuser # Copy only requirements.txt first (allows better Docker caching) COPY requirements.txt . # Install dependencies RUN python -m pip install --no-cache-dir -r requirements.txt # Now copy the rest of the application source code COPY . . # Switch to the non-privileged user to run the application. USER appuser # Run the application. CMD ["sh", "-c", "python agent_bab.py download-files && python agent_bab.py start"]

This is my requirements.txt:

livekit==0.20.0

livekit-agents==0.12.17

livekit-plugins-openai==0.10.18

livekit-plugins-cartesia==0.4.7

livekit-plugins-deepgram==0.6.18

livekit-plugins-silero==0.7.4

livekit-plugins-elevenlabs==0.8.0

livekit-plugins-turn-detector==0.4.1

livekit-plugins-assemblyai==0.2.3

python-dotenv==1.0.1

llama-index==0.12.17

geopy==2.4.1

torch==2.6.0

phonenumbers==9.0.0

transformers==4.51.3

huggingface-hub==0.30.2

ENV variables:
The only extra thing I needed on Railway was the environmental variable below to make the first/initial deployment work: HF_HOME="/tmp/huggingface"

Any help would be much appreciated, thanks!
