"Missing flux value" when fitting tutorial example

I am running ariadne on a native conda+python install on a M1 macbook, using macOS Monterey v12.3, and cannot complete the default fitting shown in the tutorial, as shown below:

from astroARIADNE.star import Star ra = 75.795 dec = -30.399 starname = 'NGTS-6' gaia_id = 4875693023844840448

s = Star(starname, ra, dec, g_id=gaia_id)

from astroARIADNE.fitter import Fitter

out_folder = '/Users/jonathan/Documents/Python/Python_Packages/ariadne_outputs/tutorial'

engine = 'dynesty' nlive = 500 dlogz = 0.5 bound = 'multi' sample = 'rwalk' threads = 4 dynamic = False

setup = [engine, nlive, dlogz, bound, sample, threads, dynamic]

models = [ 'phoenix', 'btsettl', 'btnextgen', 'btcond', 'kurucz', 'ck04' ]

f = Fitter() f.star = s f.setup = setup f.av_law = 'fitzpatrick' f.out_folder = out_folder f.bma = True f.models = models f.n_samples = 100000

f.prior_setup = { 'teff': ('default'), 'logg': ('default'), 'z': ('default'), 'dist': ('default'), 'rad': ('default'), 'Av': ('default') }

f.initialize() f.fit_bma()

        FITTING MODEL : phoenix
