andes.core.service.NumSelect

class andes.core.service.NumSelect(optional, fallback, name: str | None = None, tex_name: str | None = None, info: str | None = None, ignore_cond: ~typing.Callable | None = functools.partial(<ufunc 'equal'>, 0))

Class for selecting values for optional NumParam.

NumSelect works with internal and external parameters.

Any values equal to np.nan will always be ignored. If one needs to ignore values based on additional conditions, pass it through ignore_cond. For example, to ignore zero values, use ignore_cond = partial(np.equal, 0).

Examples

One use case is to allow an optional turbine rating. One can do

self.Tn = NumParam(default=None) self.Sg = ExtParam(...) self.Sn =
DataSelect(Tn, Sg)

__init__(optional, fallback, name: str | None = None, tex_name: str | None = None, info: str | None = None, ignore_cond: ~typing.Callable | None = functools.partial(<ufunc 'equal'>, 0))
