Solve the following python programming problem given the following code:
def _test_compare(self, pyfunc) : 
    def eq(pyfunc, cfunc, args) : 
        self.assertIs (cfunc (* args), pyfunc (* args), ('mismatch for arguments %s' % (args,))) 
argtypes = [types.Tuple ((types.int64, types.float32)), types.UniTuple (types.int32, 2)] 
    for (ta, tb) in itertools.product (argtypes, argtypes) : 
        cr = compile_isolated (argtypes, (ta, tb)) 
        cfunc = cr.entry_point 
        for args in [((4, 5), (4, 5)), ((4, 5), (4, 6)), ((4, 6), (4, 5)), ((4, 5), (5, 4))] : 
            eq (pyfunc, cfunc, args) 
argtypes = [types.Tuple ((types.int64, types.float32)), types.UniTuple (types.int32, 3)] 
    cr = compile_isolated (pyfunc, tuple (argtypes)) 
    cfunc = cr.entry_point 
    for args in [((4, 5), (4, 5, 6)), ((4, 5), (4, 4, 6)), ((4, 5), (4, 6, 7))] : 
        eq (pyfunc, cfunc, args) 

    
    

    Fix the buggy line: cr = compile_isolated (argtypes, (ta, tb))
assistant
#Here is Python program to fix the buggy line: cr = compile_isolated (argtypes, (ta, tb))
.

cr = compile_isolated (pyfunc, (ta, tb))
