The downside right now is that

shark-ai/sharktank/requirements.txt

Line 14 in eb1d4c3

torch>=2.3.0

is pulled in from PyPI which comes with a lot of dependencies and we cannot point to the e.g. CPU-only version if we want to publish the meta package on PyPI.

iree-turbine also has that pin: https://github.com/iree-org/iree-turbine/blob/91d8f598ca4ae5927bc0a735e17c4af8fbfaf90d/setup.py#L110. We could switch all packages to not require torch directly and instead check at import time if it is installed

I think we should proceed with this and then trim the requirements (notably torch) in a follow-up (ideally before the next stable release).

We can also explore moving some deps into extras.
