Cobaya: NaN Rminus1_cl_level
Posted: July 01 2020
I am running cobaya with mcmc sampler with des shear likelihood and all default settings, as provided by the cosmo-generator. However, when I open the progress file I see that the Rminus1_cl_level is NaN throughout. I have also tried running des shear with planck and get the same result.
As a result, my chains never converge, however, everything else seems ok. I get reasonable Rminus1 on means, I can see no NaN values in the chains, no error messages in the terminal output, the inferred parameter values and contours provided by getdist also look reasonable.
I am not even sure how to begin to troubleshoot this - perhaps someone has had a similar experience? Thanks!
