When running the test suite with Python 3.13, the Hough circle unit test is failing (see here):
KeyError: 'area_bbox' in cdl/tests/features/images/hough_circle_unit_test.py

This is apparently due to the fact that scikit-image does not support Python 3.13.
The next version (0.25) will add support for Python 3.13.

So... ⌛let's wait for scikit-image 0.25 before adding Python 3.13 support to DataLab!
