Hi @Upscale4152, currently we are doing open development for Relax in a separate repo: Relax repo. We will release a Relax Roadmap RFC this week as a start to discuss the upstreaming plan with the broader TVM community.
This Jupyter notebook contains a set of demos showing how Relax handles dynamic-shape workloads, feel free to try it out! For more details about Relax, please check out the Relax pre-RFC, the TVM Community Meeting from 04/20/2022 here, the TVMCon 2021 talk here, and design docs here.
