Cobaya: installation of cosmological codes and data

[Zhuangfei Wang]

Hello:

I just have a question on the installation of cosmological codes and data for Cobaya. Basically, by using the standard command from the website:

Code: Select all

cobaya-install cosmo -p /path/to/packages

I couldn't find the planck package being installed, that used to be under the code directory alongside CAMB and classy. There was no such issue with last version of Cobaya (3.2 and before), but it happens to the new version (3.3.1). Also, the python environment I am using is version 3.8 which meets the requirement. Could you please check out the potential problem with it? Is it because the cosmo packages are being updated or did I miss something important?

Thanks,
Zhuangfei

It doesn't install clik by default to avoid endless problems compiling clik. You can now run lowl TT, lowl EE, lensing and NPIPE TTTEEE without clik via the native python classes. You may need to install planck_NPIPE_highl_CamSpec data files, or explicitly install a clik likelihood if you want to use one of those instead.
