 **Vision**: We aim to achieve cross-hardware portability of compiler optimizations by allowing models to learn and transfer optimization strategies. It will significantly  reduce the manual effort required to develop efficient operator implementations.

 ### Dataset Construction Constraints：
 1. Dynamic graphs must execute correctly.
-2. Each computation graph should include a standardized method for measuring performance.
-3. Graphs and their corresponding Python code must support serialization and deserialization.
-4. The full graph can be decomposed into two disjoint subgraphs.
-5. Compiler passes or behaviors must be configurable.
-6. Operator names within each computation graph must be statically parseable.
-7. If custom operators are used, their implementation code must be fully accessible.
-8. Graph execution on different hardware backends must be configurable via a unified interface.
