[GitHub] [tvm] junrushao opened a new pull request, #12685: [AutoTVM][Testing] Add `tune_relay` scripts

junrushao opened a new pull request, #12685:
URL: https://github.com/apache/tvm/pull/12685

   Example:
   
   ```bash
   python -m tvm.autotvm.testing.tune_relay  \
          --workload bert_base               \
          --input-shape '[1,64]'             \
          --target "llvm"                    \
          --num-trials 800                   \
          --rpc-host 192.168.6.66            \
          --rpc-port 4445                    \
          --rpc-key 3090ti                   \
          --work-dir /logs/autotvm-bert_base \
          --cache-dir /cache-workloads       \
          --graph-tuner True                 \
          --cpu-flush True                   \

   Thanks for asking! As indicated, it’s only used for testing purpose. We have no interest or intent to have any overlap with tvmc, but instead are using this for inspecting performance parity as a testing tool.

Review Comment:
   I feel most arguments could have a default value to at least give people some senses. For example, I have no idea about what to put to `workload` and `input-shape` in terms of options and format.

Review Comment:
   Also need to check `target`, since only CPU needs graph tuner.

   Thanks! Yeah we mainly wanted some flexibility testing things out - and I fully support it if some day you guys want to migrate similar testing logic to TVMC :-)

   > Otherwise LGTM. IMHO, it's no hurt to have testing scripts under certain module in general, as it is serving different users than TVMC. Specifically, testing scripts could be more flexible for future changes as they don't impact user experience.
   
   Actually thinking this way it makes sense. Thanks @comaniac
