Review comment:
@hogepodge is working on a fairly extensive refactor of the TVM
tutorials--I think we should ensure there is a place for stuff like this. it
would still be helpful to see your tutorial or perhaps the python scripts
you're using with this code! perhaps there are other pieces we are missing or
should checkin, or perhaps there is a particular way we should structure our
docs to make this use case more straightforward.
