python2.7 paddle 1.5.2 cpu 多核

A方式使用： with_data_parallel会报错。 B方式正常运行。 调用方式如下

                exec_strategy = fluid.ExecutionStrategy()
                build_strategy = fluid.compiler.BuildStrategy()
                # A
                compiled_prog = fluid.compiler.CompiledProgram(train_prog).with_data_parallel(loss_name=cost.name,  build_strategy=build_strategy,   exec_strategy=exec_strategy)
               #  B               
                compiled_prog = fluid.compiler.CompiledProgram(train_prog)

报错信息如下：
