segformer model not found

I'm getting this error when running server.py:

from surya.model.detection import segformer
ImportError: cannot import name 'segformer' from 'surya.model.detection' (unknown location)

Start by reproducing the ImportError from server.py and inspect the available names under surya.model.detection. Check the project's dependency and import setup to determine why segformer is unavailable. Done means the server starts without this import failure and the expected detection model can be loaded.
