Minimal app that displays a silicon crystal structure using Crystal Toolkit and Dash.

import os from crystal_toolkit import CrystalToolkit from pymatgen.core import Structure app = CrystalToolkit(debug=os.environ.get('DEBUG', False)) # Create a simple crystal structure si = Structure.from_spacegroup('Fd-3m', [[0,0.5,0.5],[0.5,0,0.5],[0.5,0.5,0]], ['Si']) # Add a structure viewer component @app.callback @app.structure_viewer(si) def display_structure(): return 'Hello from Crystal Toolkit' if __name__ == '__main__': app.run()

Known issues

breakingCrystal Toolkit 2024+ dropped support for Python 3.9 and earlier. Requires Python >=3.10.

fix

Upgrade to Python 3.10 or newer before installing crystal-toolkit.

affects: >=2024.0.0

deprecatedThe legacy `CrystalToolkitApp` class has been removed. Use `CrystalToolkit` instead.

fix

Replace `from crystal_toolkit import CrystalToolkitApp` with `from crystal_toolkit import CrystalToolkit`.

affects: >=2025.0.0

gotchaDo not install crystal-toolkit and dash separately as different versions may conflict. Let crystal-toolkit manage dash version.

fix

Install only crystal-toolkit; dash is pulled as dependency.
