interp2d` has been removed in SciPy 1.14.0.

Suggest replacing with "RegularGridInterpolator"

Quick hack is to declare the following at the top of src/Diagnostics.py:

from scipy.interpolate import RegularGridInterpolator

def interp2d(lon0, lat0, values, kind="cubic"):
    rgi = RegularGridInterpolator(
        (lat0, lon0),          # values must be shaped as (lat, lon)
        values,
        method=kind,
        bounds_error=False,
        fill_value=np.nan,
    )

    def f(lon_new, lat_new):
        lon_new = np.asarray(lon_new)
        lat_new = np.asarray(lat_new)

        lon2, lat2 = np.meshgrid(lon_new, lat_new, indexing="xy")
        pts = np.column_stack((lat2.ravel(), lon2.ravel()))

        return rgi(pts).reshape(lat2.shape)

    return f
