Solve the following python programming problem given the following code:
def check_h5_settings(f, n, dim, min_dist = None, names = None, cats = None, write = False) : 
    '
    Checks that the hdf5 div cache file has settings that agree with the
    passed settings. If write, adds them to the file if not present.
    ' 
    if any (((divs.shape != (n, n)) for (name, div_group) in f.items () if (name != '_meta') for divs in div_group.values ())) : 
        raise ValueError ('existing divs have wrong shape') 
if ('_meta' in f) : 
        meta_group = f ['_meta'] 
        def check(name, value) : 
            if np.any ((meta_group [name] [()] != value)) : 
                raise ValueError ("attribute '{}' differs in file".format (name)) 
else : 
        if write : 
            meta_group = f.require_group ('_meta') 
            def check(name, value) : 
                meta_group [name] = value 
else : 
            meta_group = None 
            def check(name, value) : 
                pass 
check ('dim', dim) 
    check ('min_dist', (default_min_dist (dim) if (min_dist is None) else min_dist)) 
    for x in ['names', 'cats'] : 
        if ((divs is not None) and (x in meta_group)) : 
            if (meta_group [x].shape != (n,)) : 
                raise ValueError ("'{}'' has wrong shape in file".format (x))

        reconcile_file_order (f, names = names, cats = cats, write = write)
