+`NumpyModel.load` requires the original mode, use `model_agnostic_load` when you have several models, and you want to load into a set of possible models.

 ### Data type (dtype) support!
 
 This package also comes with `pydantic_numpy.dtype`, which adds subtyping support such as `NDArray[float, pnd.float32]`. All subfields must be from this package as numpy dtypes have no Pydantic support, which is implemented in this package through the [generic class workflow](https://pydantic-docs.helpmanual.io/usage/types/#generic-classes-as-types).
