Looking up the parameters of a theory

The parameters for all of the theories can be found in the theory.db file, located in the <NNPDF install location>/share/NNPDF/data directory. This is an sqlite database file.

The tools required to extract the parameters for a given theory are already in the validphys framework:

>>> from validphys.loader import Loader

>>> l = Loader()
>>> # replace 53 with the relevant theoryID
>>> info_dict = l.check_theoryinfo(53)
>>> print(info_dict)
