Missing comma in Multinest.py breaks multinest

[arthurmloureiro]

Hi!

After a few days bashing my head agains the wall to get Multinest to work, always finding the classic:

 /!\ PyMultiNest detected but MultiNest likely not installed correctly. You can
     safely ignore this if not running with option -m NS

I tried to reverse engineer the error and noticed this:

In [1]: from MultiNest import NS_prefix, NS_user_arguments
Traceback (most recent call last):

  File ~/.local-co/envs/env/lib/python3.10/site-packages/IPython/core/interactiveshell.py:3579 in run_code
    exec(code_obj, self.user_global_ns, self.user_ns)

  Cell In[1], line 1
    from MultiNest import NS_prefix, NS_user_arguments

  File ~/Github/montepython_public/montepython/MultiNest.py:98
    'base_dir': {'type': str}
                ^
SyntaxError: invalid syntax. Perhaps you forgot a comma?

Indeed, there's a comma missing in line 98:

NS_auto_arguments = {
    'base_dir': {'type': str}
    'n_dims':   {'type': int},
    'n_params': {'type': int},
    'verbose':  {'type': str2bool},
    'outputfiles_basename': {'type': str},
    'init_MPI': {'type': str2bool}
    }

specifically after 'base_dir': {'type': str} . Happy to send a PR once I figure out why the Planck Likelihood still doesn't run with Multinest.

I encountered the same problem. Thank you for the solution.
