np.int was removed in NumPy 1.24, and the project pins numpy<2, so no supported NumPy version defines it. nstates returns len(self.electronic_states), a builtin int, so the annotation was also semantically wrong. It is currently masked only because 'from __future__ import annotations' makes annotations lazy strings, but typing.get_type_hints() on this class would raise AttributeError. This is the only such deprecated alias left in the codebase.

Summary
mlatom/data.pyannotates thenstatesproperty with the removed aliasnp.int:np.intwas deprecated in NumPy 1.20 and removed in NumPy 1.24. Sincepyproject.tomlpinsnumpy<2, every supported NumPy (1.24–1.26) lacks this attribute. The property returnslen(self.electronic_states)— a builtinint— so the annotation was also semantically incorrect.It doesn't crash on import only because
from __future__ import annotationsmakes annotations lazy strings, but anytyping.get_type_hints()on this class raisesAttributeError: module 'numpy' has no attribute 'int'.Fix
One-line, behavior-preserving. This is the only remaining deprecated NumPy alias (
np.int/np.float/np.bool/np.object) in the codebase.
