[mlc] [Exercises for TensorIR] How to do an inverse transform, transform TargetModule to MyBmmRelu module?

I am learning mlc course, on the [ Exercise 3: Transform a batch matmul program] section. I complete transform source module to target module, but how to do the inverse transform? (Would like every transform has an inverse transform.)

Part of the transformations have inverse operations, such as (fuse/split, annotate/unannotate), but most of them cannot transform inversely.

Hi, could you take an example and tell why? Thanks.
