[scikit-learn] Is there any official position on PEP484/mypy?

[Daniel Moisset]

If the dependency is really a showstopper, bundling could be an option. The
module is a single, pure python file so that shouldn't complicate things
much.

@Joel, regarding
«without ndarray/sparse matrix type support, we're not going to be able to
annotate most of our code in sufficient detail»

That shouldn't be a problem, we have already written some working support
for numpy at https://github.com/machinalis/mypy-data, so it's possible no
annotate ndarrays and matrix types (scipy.sparse is not covered yet, I
could take a look into that).

Best,
    D.
