PyPartMC

✓ import PyPartMC

Top-level module, not pypartmc or partmc

Initialize aerosol species data, create gas state, set concentrations.

import PyPartMC as ppmc import numpy as np aero_data = ppmc.AeroData( ["SO4", "NaCl"], [ppmc.AeroData.species_data("SO4", density=1.8, kappa=0.5), ppmc.AeroData.species_data("NaCl", density=2.16, kappa=1.0)] ) state = ppmc.GasState(aero_data) state.set_conc(np.array([1e-5, 2e-5])) print(state.conc)

Debug

Known issues

breakingPyPartMC v2.0.0 switched from pybind11 to nanobind. Code compiled against previous versions may need reinstallation. The module import path remains 'PyPartMC'.

fix

Reinstall pypartmc and ensure all dependencies are up-to-date.

affects: >=2.0.0,<3.0.0

gotchaAlways use 'import PyPartMC', not 'import pypartmc' or 'import partmc'. The package name is pypartmc on PyPI, but the Python module is PyPartMC (case-sensitive).

fix

Use 'import PyPartMC'.

affects: all

deprecatedSome older functions (e.g., AeroData.from_json) may be removed in future versions. Check the changelog for deprecation notices.

fix

Check documentation for current API.

affects: >=2.0.0

Errors

Common errors & fixes

ImportError: No module named PyPartMC

The Python module is named 'PyPartMC', but package is 'pypartmc'. You may have installed the wrong package or used wrong import.

fix

Run 'pip install pypartmc' and then 'import PyPartMC'.

ModuleNotFoundError: No module named 'partmc'

Common mistake: trying to import 'partmc' instead of 'PyPartMC'.

fix

Use 'import PyPartMC'.

ValueError: species 'SO4' not found

AeroData species definitions must include all properties (density, kappa). Missing or misnamed species cause this.

fix

Provide complete species_data for each species, e.g., ppmc.AeroData.species_data('SO4', density=1.8, kappa=0.5).
