挂了呢，应该用暴露的 API paddle.autograd.PyLayerContext
| data.stop_gradient = False | ||
| # run custom Layer. | ||
| z = cus_tanh.apply(data, func1=paddle.tanh) | ||
| COPY-FROM: paddle.autograd.PyLayer |

这边copy from的应该是apply方法吧

@wanghuancoder 辛苦确认pylayer的apply方法，是否在源码中被删除

apply这个API是没有被删的，他是PyLayer最基础的入口。是现在C++里面。所以在英文源代码中没找到文档。但是在多个示例代码里都有使用到。
