Planck likelihood code 2018

[SafaeCosmology]

Hello everyone, I have problem with installing the Planck 2018 likelihood code , when I execute ''./waf configure --install_all_deps'' the following error would appear : '''testing pyembed configuration : could not build a python embedded interpreter''' if anyone can help me solve this problem. thank you in advance.

Hi @SafaeCosmology , Have you installed cython? And also can you please elaborate your problem. I mean show me the whole set of errors you got so that I can understand your problem well. Then I will see if I could help .

[SafaeCosmology]

Thank you very much @shan1525 for your answer, the problem is solved, when I changed the version of Python 2.7 which is compatible with Planck, but when i run montepython, I get the following error: ''AttributeError: 'module' object has no attribute 'lkl' '' I don't know what the problem is, knowing that I followed all the steps indicated in #68.

Hi, Could you provide the complete error message? What parameter file are you running, and with what command? We need this information to try to debug your issue.

Also I would not recommend downgrading to Python 2.7: this is deprecated and many modules (including numpy and scipy) no longer have support, and therefore may cause unfixable bugs and issues.

Best, Deanna

Thank you very much @dchooper for your reply, the parameter file , that I used is the following:

---

data.experiments=['Planck_lowl_TT']

------ Parameter list ------

Cosmological parameters list

data.parameters['omega_b'] = [2.249, -1,-1, 0.016, 0.01,'cosmo'] data.parameters['omega_cdm'] = [0.1120, -1,-1, 0.0016,1, 'cosmo']

data.parameters['A_planck'] = [ 1.00061, 0.9, 1.1, 0.0025, 1, 'nuisance']

Derived parameter list

data.parameters['Omega_Lambda'] = [0, -1, -1, 0,1, 'derived'] data.parameters['sigma8'] = [0.8, None, None, 0, 1, 'derived']

------ Mcmc parameters ----

Number of steps taken, by default (overwritten by the -N command)

data.N=10

Number of accepted steps before writing to file the chain. Larger means less

access to disc, but this is not so much time consuming.

data.write_step=5

---

when I use only Pantheon data (for example) , MontePython works, but when I add 'Planck_lowl_TT data, it gives me the following error.

Hi @SafaeCosmology , Thanks @dchooper for elaborating my query. I think @SafaeCosmology that when you are installing the likelihood, it is searching for the library libcfitsio.so.9 which is not installed in your system. I would suggest you to install cfitsio. You can find the link for cfitsio in readme file. I think this will resolve your issue.

Best, Shan

[shan1525]

Sorry I forgot to ask, have you installed the plik code itself. If you have installed it already,then don't mind the question.

[SafaeCosmology]

Hi @shan1525 thank you for your reply, yes I have installed the CFITSIO library available at https://heasarc.gsfc.nasa.gov/fitsio/, and also the plik code . I don't know what the problem is :/ .

[dchooper]

Hi, Have you tested if the plik code itself is working independently of MP? One quick way to do this is to run clik_print (make sure you have the Planck likelihood sourced first, and then you can run that in any directory). You should see something like usage : %s lkl_file If instead you get an error message, then the issue is directly with the Planck likelihoods and not with MP. Let me know how the test goes. Best, Deanna

[SafaeCosmology]

finally, the problem is solved thank you so much @dchooper and @shan1525, Best regards. SAFAE

[dchooper]

Hi Safae, Great news! If you could, it would be great if you could add a comment with what the problem and solution were, in case someone else encounters the same issue in the future. Best, Deanna

[SafaeCosmology]

Hi @dchooper, Yes of course, I just used the following commands: cd Planck / code / plc_3.0 / plc-3.01 ./waf config --install_all_deps --cfitsio_lib = / home / .................. / Desktop /cfitsio-3.49 / lib

Instead of [./waf configuration --install_all_deps'], lib is the directory where the libcfitsio.so.9 library is located, of course after a good installation of CFITSIO. Best regards. Safae

Thanks for posting the solution Safae!
