Cobaya: Could not find random point giving finite posterior error

[Dror Berechya]

Hello all,

I am a new user of Cobaya. I try to run "cobaya-run [input YAML file] --test", and I get this error message:

[mcmc] Getting initial point... (this may take a few seconds)
[model] *ERROR* Could not find random point giving finite posterior after 1080 tries

Do you know what it means, and how can I fix it?

Thank you in advance for your response!

Run with --debug to see values and points it is trying. Normally the likelihood is wrong, or parameter values are not set up sensibly.
