Cannot import module AutoProcessor

I have the following issue with installing the version 2.81.0 of docling. From the likes of it, there is a mismatch between the transformer version used inside docling and the presence of AutoProcessor.

from docling.document_converter import DocumentConverter

Reproduce the import from docling.document_converter and follow the traceback through docling/pipeline/base_pipeline.py and docling/models/stages/chart_extraction/granite_vision.py, where AutoProcessor is imported. Check the installed Transformers, Torch, and torchvision versions and the project’s dependency declarations. Done means importing DocumentConverter succeeds on the supported Python environment without the AutoProcessor error.
