About the instalation of cosmo with cobaya

[Clara Rojas]

Dear Antony,

We are trying to work with cobaya, but when try to do the instalation of Cosmo:

cobaya-install cosmo -p /path

We obtain the following error messages:

[install] *ERROR* The installation (or installation test) of some component(s) has failed:
- theory:camb
- theory:classy
Check output of the installer of each component above for precise error info.

cobaya.log.LoggedError: The installation (or installation test) of some component(s) has failed:

Can you help us to solve this error, please?

Dear Antony,

Finally I can to install CAMB and CLASS but I still have problems with the likehood of Planck, I try doing

cobaya-install planck_2018_highl_plik.TTTEEE

I obtain the same error that I obtained when try to install using waf

Checking for program 'gcc, cc' : /usr/local/bin/gcc
gcc not found(cause : Could not find gcc/g++ (only Clang), if renamed try eg: CC=gcc48 CXX=g++48 waf configure

Any suggestion?

Hi again,

I do not sure what I did but now when a run the command:

cobaya cobaya-install planck_2018_highl_plik.TTTEEE

I obtained the following error:

Traceback (most recent call last):
File "/opt/homebrew/bin/cobaya", line 8, in <module>
sys.exit(run_command())
File "/opt/homebrew/lib/python3.9/site-packages/cobaya/__main__.py", line 15, in run_command
metadata.entry_points().select(group="console_scripts")
AttributeError: 'dict' object has no attribute 'select'

Any idea what is the problem?

Thanks very much,
Clara

You don't want the first "cobaya", just "cobaya-install".

There are native python Planck likelihoods available with Cobaya that avoid clik.

Dear Antony,

Thanks for your soon answer.

I have a mistake when copy the question yesterday, I actually running the command:

cobaya-install planck_2018_highl_plik.TTTEEE

And I found the following error:

The configuration failed
(complete log in /Users/crojas/Documents/Research/inflation/code/planck/clik-main/build/config.log)

[clik] *ERROR* Configuration failed!
[planck_2018_highl_plik.TTTEEE] *WARNING* clik code installation failed! Try configuring+compiling by hand at /Users/crojas/Documents/Research/inflation/code/planck
[install] *ERROR* Installation failed! Look at the error messages above. Solve them and try again, or, if you are unable to solve them, install the packages required by this component manually.

Thanks,
Clara

Sounds like a problem with clik (as usual..), not cobaya.
Make sure you can install and use clik separately first before trying with cobaya.
