# scipy 1.18 (py3.12+) changed interpolators to return arrays for scalar
# input, which breaks camb's BBN Y_He predictor inside set_cosmology
# (`TypeError: only 0-dimensional arrays can be converted to Python
# scalars`), failing all get_cosmo-backed tests. Cap until camb ships a fix.
# scipy 1.18 ported FITPACK from Fortran to C, changing the return shape of
# RectBivariateSpline(scalar, scalar, grid=False) from 0-d `array(x)` to
# shape-(1,) `array([x])`. camb's BBN Y_He predictor (bbn.py) wraps the
# result in np.float64(), which collapses a 0-d array to a scalar but leaves
# a (1,) array as (1,); set_cosmology then fails at the ctypes float
# assignment `self.YHe = YHe` with `TypeError: only 0-dimensional arrays can
# be converted to Python scalars`, failing all get_cosmo-backed tests. camb
# 1.6.6 (latest on PyPI) and current master are both unfixed. Lift this cap
# when camb ships > 1.6.6 with the scipy-1.18 fix.
