设备是：华为ATLAS 200I DK A2开发者套件，CANN版本是：7.0.rc1，使用ATC进行模型转换时出现如下报错：Expand算子不支持，但是CANN文档中是支持的，请问这是怎么回事？

报错信息如下：

        Possible Cause: The operator type is unsupported in the operator information library due to specification mismatch. 

        Solution: Submit an issue to request for support at https://gitee.com/ascend, or remove this type of operators from your model.
