I would also like to point out that, --install-types --non-interactive will install the missing package stubs hence slower.

Quoting relevant part from the above documentation link :- This is somewhat slower than explicitly installing stubs before running mypy, since it may type check your code twice – the first time to find the missing stubs, and the second time to type check your code properly after mypy has installed the stubs.

I don't think downloading the package stubs would be a bottleneck; but if it is, then we could think of using cached installations. (just a suggestion)

Thank you for providing the idea. I think it's fine for now as torchdata is still a small package. We might want to investigate if we have noticed significant overhead.
