Solve the following python programming problem given the following code:
def _loadarff(ofile) : 
    try : 
        (rel, attr) = read_header (data) 
except ValueError as e : 
        msg = ('Error while parsing header, error was: ' + str (e)) 
        raise ParseArffError (msg) 
hasstr = False 
    for (name, value) in attr : 
        type = parse_type (value) 
        if (type == 'string') : 
            hasstr = True 
meta = MetaData (rel, attr) 
    acls2dtype = { 
        'real' : float, 
        'integer' : float, 
        'numeric' : float, 
} 
    acls2conv = { 
        'real' : safe_float, 
        'integer' : safe_float, 
        'numeric' : safe_float, 
} 
    descr = [] 
    convertors = [] 
    if (not hasstr) : 
        for (name, value) in attr : 
            type = parse_type (value) 
            if (type == 'date') : 
                (date_format, datetime_unit) = get_date_format (value) 
                descr.append ((name, ('datetime64[%s]' % datetime_unit))) 
                convertors.append (partial (safe_date, date_format = date_format, datetime_unit = datetime_unit)) 
else : 
                if (type == 'nominal') : 
                    n = maxnomlen (value) 
                    descr.append ((name, ('S%d' % n))) 
                    pvalue = get_nom_val (value) 
                    convertors.append (partial (safe_nominal, pvalue = pvalue))

                    descr.append ((name, acls2dtype [type])) 
                    convertors.append (safe_float) 
else : 
        raise NotImplementedError ('String attributes not supported yet, sorry') 
ni = len (convertors) 
    def generator(row_iter, delim = ',') : 
        elems = list (range (ni)) 
        for raw in row_iter : 
            if (r_comment.match (raw) or r_empty.match (raw)) : 
                continue 
row = raw.split (delim) 
            (yield tuple ([convertors [i] (row [i]) for i in elems])) 
a = generator (ofile) 
    data = np.fromiter (a, descr) 
    return (data, meta) 

    
    

    Fix the buggy line: (rel, attr) = read_header (data)

#Here is Python program to fix the buggy line: (rel, attr) = read_header (data)
.

(rel, attr) = read_header (ofile)
