 | Operator generated by constexpr     |Uses the value generated by [@constexpr](https://www.mindspore.cn/api/en/master/api/python/mindspore/mindspore.ops.html#mindspore.ops.constexpr) to calculate operators.
 
+### Mixed Mode
+ It is not recommended to use dynamic graph mode (PyNative) and static graph mode for network construction at the same time.
+
 
 ### Other Constraints
 Input parameters of the construct function on the entire network and parameters of functions modified by the ms_function decorator are generalized during the graph compilation. Therefore, they cannot be transferred to operators as constant input, as shown in the following example:

+### 混合模式
+ 不建议同时使用静态图模式(PyNative)和动态图模式来构造网络。
 
 ### 其他约束
 整网construct函数输入的参数以及使用ms_function装饰器修饰的函数的参数在图编译过程中会进行泛化，不能作为常量输入传给算子使用，如下例所示：
