I ran 50000 steps with the Planck-2018 TT data firstly without a covariance matrix and got an abysmal acceptance rate of ~0.01.
During this run, it often gave this message ("failed to calculate covar…

I have a single sample with ~2500 ssms running but it seems to have slowed down after about 700 mcmc samples and now is making very little progress. It has completed fewer than 100 mcmc samples in the…

This is an FYI / guidance for those who are currently running `cmdstanpy>=1.0.2`, specifically when doing full MCMC sampling (`mcmc_samples > 0`). We've noticed that `cmdstanpy` now logs warnings fair…
