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

Questions
#1

I am learning mlc course, on the [2.5.2.2. 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.)

#2

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

#3

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