   > @cbalint13, appreciate sharing your thoughts! I also think this is a great out-of-tree approach and look forward to its actual usage.

   > I agree that the overall docstring structure (e.g., Vanilla, Strawberry & Chocolate) would be a great introduction/tutorial (Truly appreciate the authors!). My issue was more like a code-level docstring since some of them are missing and I wasn't sure what each function or parameter exactly means. https://github.com/apache/tvm/blob/bc211fdc91932ef9b77f7edd2ff65151ee5faaff/python/tvm/relay/backend/contrib/uma/_template/codegen.py https://github.com/apache/tvm/blob/bc211fdc91932ef9b77f7edd2ff65151ee5faaff/python/tvm/relay/backend/contrib/uma/_template/codegen.py

   > I see. Thank you for the clarification! Maybe my example was not relevant. I just thought it would be nice to have some model-level test cases since we seem to have all necessary components (UMA Partitioner, UMA Pipeline, UMA Lower, UMA Codegen) in this PR. I just wanted to see if current PR also covers a case where we lower some parts with UMA while handling other unsupported parts via the conventional pipeline.
   
   We have an example testcase for running MobileNet (created in Relay) with uma and the Vanilla Accelerator in place. Not sure if it should be added to this PR or a later one, as this PR already is a lot to discuss. I'd be in favor of moving this to the next UMA PR.
