I normally have to work with both CLASS and hi_class. Although hi_class is an implementation on top of CLASS, the versions of CLASS roll faster than those of hi_class, so CLASS bugs can be still present on hi_class. More importantly, I might want to keep running one LCDM MCMC and launch a MG one (which might involve go to a new branch y recompile the code). However, I think that recompiling hi_class can potentially create some problems with the LCDM run.

What would you think of changing the value of the python module to hiclassy or something like that, so that one can have both codes installed at the same time?

I was trying to install hi_class in Ubuntu 18.04 with gcc 7.5.0. I can run the python scripts and everything works fine however when I try to run ./class explanatory.ini I get the following:

`Reading input parameters
-> matched budget equations by adjusting Omega_Lambda = 6.878622e-01

Error running input_init_from_arguments
=>input_init_from_arguments(L:179) :error in input_init(&fc, ppr, pba, pth, ppt, ptr, ppm, psp, pnl, ple, pop, errmsg);
=>input_init(L:459) :could not open param_output with name output/explanatory00_parameters.ini and mode "w"`

Any recommendations to fix the problem?

Extra information:
I don't get any problem with class.

Hi! I'm trying to test gravity models using hi_class and montepython, but i'm not sure how to implement the smg parameters in the .param
In my .param I added the lines:
data.cosmo_arguments['gravity_model'] = 'galileon'
data.cosmo_arguments['gravity_submodel'] = 'cubic'
And this is the error:
Something went wrong when calling CLASS /_o_\ Error in Class: Class did not read input parameter(s): gravity_model, gravity_submodel

When I set up cosmos.set({"gravity_model_smg": "non_canonic_scalar"}) and then called cosmos.compute, I encountered the following error:

Traceback (most recent call last):
File "", line 1, in
File "classy.pyx", line 364, in classy.Class.compute
classy.CosmoSevereError:

Error in Class: Class did not read input parameter(s): gravity_model_smg

How can I implement Cobaya with HiClass? Also, I want to know how to specify specific gravity models and their parameters in yaml file.
