Error "ImportError: cannot import name 'packaging' from 'pkg_resources'"

Functions work locally, but on deployment to Azure the build fails with the following error:

Start by reproducing the Azure deployment using the reported Python 3.10.4 environment and the openpifpaf dependency, then trace the pip build-isolation failure involving setuptools, torch, and pkg_resources. Done means the deployment build completes without the reported ImportError; the issue names no repository files or tests to run.
