We ship everything needed for userland -- including parts of CUDA/CuBLAS and CuDNN that we need (which is why our binaries are so fat).

GPU drivers would be kernel-land and I don't think we actually can install GPU drivers as part of a `pip install`. Will look into what Flux is doing, but I doubt they ship GPU drivers.

Separately, thanks for flagging the Poetry issue, we might prioritize it, especially if the fix is easy.
