cobaya error: simple initializing of the Planck likelihoods

Post by boryana hadzhiyska » April 28 2021

I am trying to initialize an example run with the Planck likelihoods using cobaya.
The first thing I tried was to copy the example yaml file from here: and run it with cobaya-run planck.yaml. I did this for both class and camb, but both times I got:

Code: Select all

[output_mpi] Output to be read-from/written-into folder '.', with prefix 'planck_camb'
/users/boryanah/.local/lib/python3.6/site-packages/numba/core/ UserWarning: Insufficiently recent colorama version found. Numba requires colorama >= 0.3.9

[camb] Initialized!
[clik] Importing *auto-installed* clik (but defaulting to *global*).
[] *ERROR* An unexpected error occurred in clik (possibly related to multiple simultaneous initialization, or simultaneous initialization of incompatible likelihoods (e.g. polarised vs non-polarised 'lite' likelihoods. See error info below:

[exception handler] Some unexpected ERROR occurred. You can see the exception information above.
We recommend trying to reproduce this error with 'debug:True' in the input.
If you cannot solve it yourself and need to report it, include the debug output,
which you can send it to a file setting 'debug_file:[some_file_name]'.
The only likelihoods that do not give me that error are the high TTTEEE and the lowl for TT. For the other ones, even if I select just one likelihood it produces the same error message. I thought that the readthedocs may not be updated, so I tried 

Code: Select all

after pip installing the two modules: pyqt5 and pyside2, but that gave me the following error:

Code: Select all

ImportError: module 'cobaya.cosmo_input' has no attribute 'gui_script'
I am using python3.6 and have upgraded cobaya and pip.

Sounds like a clik problem. There's an update available on the PLA which may (or may not) help. Check if clik works OK separately.
