live point's likelihood not valid

[npassaleva]

Dynesty version: 2.1.2

SETUP: with MPIPool() as pool: if not pool.is_master(): pool.wait() sys.exit(0)

                    dsampler = dynesty.NestedSampler(lnlike, log_prior_nested, ndim=ndim,
                                                bound='multi', sample='unif', rstate=rstate, pool=pool)
                    dsampler.run_nested(checkpoint_file=dir_out+dynestysave)

Hi my dynesty sampling is stopping because the of the error: "The log-likelihood of live point is invalid". I was wondering how I can overcome this problem. I've already launched my code with the same likelihood but different data set and it works so I can't figured out which is the problem. Thank you

I apologize, is it now correct?

[segasai]

Thanks The error means that your likelihood returns values that either +Inf or NaN which is not allowed.

Is there a way to check the values of the parameters that produce these results?

[segasai]

i would suggest inserting print statements inside your function.
