alt Hacker NewsI didn't know that, thanks for sharing. It makes sense, but then it also makes me wonder why none of the deep learning libraries (Torch, Jax/NNX, Eigen etc...) make this information available. Instead, ML people all have their own schemes for tracking shape information, like commenting '# (b, n, t)' on every line, or suffixing shapes to variable names - and in my experience it's a common source of bugs.

Both of these "make it available". Just because people don't know how to use/find them doesn't mean they're not "available".
> Eigen
This is not an ML anything, it's a linear algebra library.

There's a difference between tracking shapes in the compiler and specifying shapes in the model.
