mypy error: Skipping analyzing 'spacy.tokens': found module but no type hints or library stubs

See original GitHub issue

Not a real bug - just static type checker being unhappy.

How to reproduce the behaviour

Create file tmp.py

from spacy.tokens import Doc

> mypy tmp.py                                                                                                                                                                ─╯

Explosion’s blog post regarding spaCy 3.0 says:

spaCy’s user-facing API that’s implemented in pure Python (as opposed to Cython) now comes with type hints

Since Doc is implemented in Cython, there are in fact no type hints, so @mr-bjerre , you should not be looking for VSCode issues.

@svlandeg , are there any plans to annotate the Cython code with type hints? The most straight forward way would be to create a pyi file corresponding to every .pyx file, and then including a py.typed file with the word partial in it (all of this is from PEP 561 ). PS: Just for completeness, apparently it’s possible forwrite Cythonized code solely using type hints. But I don’t think this approach is battle tested enough to try out in a big library like spaCy …

Hi, is there any followup on this issue ? I stumbled on the same problem and cannot get mypy typings because of the Cython classes…

Is it planned to add some pure python typings or in python/mypy to lookup for cython code ?

Thanks in advance, Have a great day !
