Load example data, fit CCDC, and print detected changes.

from pyxccd import CCDC, load_example_data import os # Load example dataset (Landsat time series) data = load_example_data() # Initialize CCDC model model = CCDC() # Fit the model model.fit(data['time'], data['bands']) # Get change results changes = model.get_changes() print(changes)

Debug

Known issues

breakingIn version 1.0.3, the CCDC model's `get_changes` method returns a pandas DataFrame instead of a dictionary as in pre-1.0 releases.

fix

Update code to handle DataFrame output; use `.to_dict()` if needed.

affects: >=1.0.0

gotchaThe `load_example_data` function only works if the package data files are installed. If using a minimal installation (without data), call `pyxccd.download_example_data()` first.

fix

Run `from pyxccd import download_example_data; download_example_data()` before loading data.

affects: all

deprecatedThe `CCDC` class parameter `n_components` is deprecated in favor of `n_breakpoints`. Using `n_components` will raise a warning.

fix

Replace `n_components` with `n_breakpoints` in the constructor.

affects: >=1.0.0

breakingIn version 1.0.0, the internal module structure was reorganized. Direct imports from `pyxccd.ccdc` or `pyxccd.models` will fail.

fix

Use top-level imports (e.g., `from pyxccd import CCDC`).

affects: >=1.0.0
