Inf value for Loglkl

[ash2223]

Hello! I'm trying to run pyactlike with MontePython on my cluster, but i'm getting -LogLkl = inf in my chains:

I went into the init.py file and found that the analysis never makes it past the line cl = self.get_cl(cosmo, 6000) before it throws an error and sets Loglkl to inf. I'm wondering if I could get some help on bypassing this issue? Thank you!

Ah, I figured out what the issue was! Turns out "data.cosmo_arguments['l_max_scalars'] = 6000" must be added to the .param file, otherwise the default value that CLASS uses for l_max_scalars is zero, and the get_cl function won't work. Perhaps someone could add this line to the .param file so that this issue will be resolved for others who run into it. Thanks all!

Dear @ash2223 and @xzackli ,

I am running the MontePython interface for ACT pol_lite likelihood. The param file that is attached with the likelihood gives inf -Loglkl. So as suggested in this thread I used "data.cosmo_arguments['l_max_scalars'] = 6000". The error was resolved but the -loglkl is continiously increasing and the chains are not converging. So as raised in #12, is there any starting covmat and bestfit files. Or is their anything more to get a convergence? Can anybody suggest any solution to this problem. I am using only the act_likelihood with the tau_prior likelihood as given in param file.

with the best regards,
shan.
