Research direction

Start with the how-to-detect-and-count-objects-in-polygon-zone notebook and the reported test.py traceback, especially lines 62-63, using Python 3.9. Reproduce the counting path and determine why the label formatting raises a TypeError; done means the notebook completes counting without that error.
