There was a problem hiding this comment.
Due to the inconsistency of the stop_gradient behavior of dynamic graphs and static graphs,we should consider refactoring the dynamic graph unit test framework in the future.

Describe
本次PR主要cherry-pick以下两个pr：
1.基于yaml自动代码生成支持cast op 反向复用前向实现无限阶并且添加二三阶单测。
修复高阶单测框架bug，在测试时数据准备阶段应该设置output的stop_gradient为False，否则可能会导致单测框架报错（主要原因是因为静态图下stop_gradient传递性未对齐动态图）。 PR46173
2.基于Yaml自动代码生成，通过配置sign_grad yaml ,利用sign_grad去复用scale前向动态图api实现无线阶并且补充二三阶单测。 PR46002
