No radical Subgraph optimization for TensorRT

[wugoukanle]

TPAT in fact is one node by one node to optimize，namely use TVM Ansor to auto tuning one node every time，butTVM is optimized based on subgraph，as follows：

I want to know：radical subgraph optimization for TPAT is work when using TVM subgraph？modify the TVM code can realize this function？

That's correct. Ansor does auto schedule at the subgraph level.

I also agree subgraph optimization for TPAT is feasible and benifical for users. Infact, we're already working on developing this feature. Hopefully we will realese this feature 2023H1. Any suggestion/proposal are appreciated, thank you!
