//
//   1. The number of input MetaTensor is more than 3:
//      void [FunctionDesc|OpName]InferMeta(const MetaTensor& x,
//                                          const MetaTensor& y,

//                                          MetaTensor* out) {}

//   2. There are `const vector<MetaTensor*>&` in params:
