I made an experimental wrapper: https://github.com/vadimkantorov/pydlpack/blob/master/dlpack.py#L107

The most difficult part is managing memory / capsules. Currently it's sort of move-semantics (and deallocation is done in C). I'm sure you'd be able to do it better.

It would be a nice illustration in addition to existing borrowing from NumPy
