Thanks for your reply! @kevinthesun
[quote="kevinthesun, post:9, topic:7872"] Thank you for this proposal! This work does make scheduling much easier. I have a concern about using this way to write a tensor expression. It looks like more complicated than tvm.compute when defining matmul. We need to define some buffers and creating block with corresponding shape dimension. It would be helpful if you can add a conv2d example which can replace existing topi.nn.conv2d definition to better understand what developer would need to write. [/quote] In original te programming, we also have to declare buffers and create lambda expression with iter_vars having the correct shape dimension. If we take this additional info into account, TE programming is close to Hybrid Script's programming in complexity. Currently, we can not replace existing topi operators, since they are represented by Stage/Op and optimized by te schedule, while Hybrid Script will be parsed into TIR directly. [quote="kevinthesun, post:9, topic:7872"] Another question is about representing generic programming style ops such as shape functions. Since these programs don’t fit into tvm scheduling, I assume it would still be more convenient to use existing te hybrid script to create these ops? [/quote] If we don't have to schedule the PrimFunc, we don't have to declare blocks in TIR. Actually, TE hybrid script is also a text representation of TIR to a large extent, with loop and condition statement directly representing the IR structure, using sugar like variable being translated to Array of size 1 to ease the format of Store&Load. At the moment, we haven't introduced sugars to simplify such Load&Store, but the rest writing are largely simlilar. --- [Visit Topic](https://discuss.tvm.apache.org/t/rfc-tensorir-a-schedulable-ir-for-tvm/7872/10) to respond.
