Hello, Since release of ClassRegistry v5, we get the following error: ImportError: cannot import name 'EntryPointClassRegistry' from 'class_registry' As mentionned in https://class-registry.readthedocs.io/en/latest/upgrading_to_v5.html#imports EntryPointClassRegistry should now be imported with: `from class_registry.entry_points import EntryPointClassRegistry` (in vot/utilities/\_\_init__.py : 605)
