Hi! I'm using Cobaya to make cosmological MCMCs. I'm analyzing quintessence models with a modified version of CAMB. To do this, i'm configuring a hybrid OpenMP+MPI job script for GridUnesp, the cluste…

Hi @williamjameshandley,
given a completed PC run, is there a good way of predicting the runtime of a run with the same cosmology but with a different number of processes and/or live points?

Hi,
I'm just trying to write a simple external likelihood. I've put a class called `cmb_s4_chi2 ` in a module `likelihood_s4.py` which has the structure

When Polychord has more than 100 clusters, Cobaya crashes. This is because Polychord formats its output as:
```
...
log(Z_98)
log(Z_99)
log(Z_**)
log(Z_**)
...
```
Due to this formatting Cob…

When I try loading the same chains using getdist and anesthetic, the samples.loglikes value from getdist is twice as large as MCMCSamples.logL value from anesthetic. It seems that anesthetic expects g…

Looks like some things that should be zero (sigma8 when WantTransfer=False) are coming out as O(1e-310) in the chain files, cf. https://github.com/CobayaSampler/cobaya/issues/200

Dear Jesús,
I met a problem when running mcmc.
I try to run a cosmological forecast using cobaya. The constraint result is good actually, but the acceptance rate is too low, lower than 1%

This is a minor issue to note that the Pantheon data set currently used in Monte Python is out-of-date w.r.t. that used in the Planck 2018 analysis. As noted on page 24 (footnote 18) of the Planck 20…

When I run the same likelihood with different `.dataset` files I was always get the same results. The results correspond to the "default" dataset option in the `.yaml` file in the likelihood folder. I…

Hi, on a local cluster I installed cobaya with pip and auto-installed CAMB code and cosmo data with cobaya-install (except for clik which needed a bit more work). My planck-likelihood (coming from the…
