Hi Railway team,

I'm running into a deployment blocker with my Flask app using sentence-transformers==2.2.0, which depends on:

from huggingface_hub.snapshot_download import REPO_ID_SEPARATOR

This is only available from huggingface_hub>=0.24.0.

Even after explicitly setting this in requirements.txt, the deploy logs still show:

huggingface_hub version: 0.23.0 ModuleNotFoundError: No module named 'huggingface_hub.snapshot_download'

My ask:

Could you help me with one of the following:

1. Upgrade the base environment or builder so that Python libraries (esp. huggingface_hub) aren't pinned to older versions.

2. Allow full control with a Dockerfile-based deployment (if not already supported on my plan) to manage packages directly and avoid these version conflicts.

3. If Railway Nixpacks is enforcing cached dependencies, can I opt into a full cache purge or switch to a clean build pipeline?

I’m happy to upgrade to a paid plan if that unlocks more consistent dependency control.

Thanks in advance for your help!
