Tl;dr: come to our talk Catching Tensor Shape Errors Using the Type Checker at the PyCon 2021 Typing Summit next week! https://us.pycon.org/2021/summits/typing/

Longer version: over the past year a small group of us have been thinking about how to use Python's type system to make tensor/array shape information more visible, and to catch shape errors automatically using type checkers. In this talk we'll discuss our tentative solution, talking about a) how it works, b) some examples of what it looks like in practice, and c) what its limitations are.

Hope to see you there!
