There is at least one custom implementation in `Generator` IIRC, so a formal API addition sounds like a good idea. Kevin On Thu, Oct 15, 2020 at 8:52 PM Stephan Hoyer <shoyer@gmail.com> wrote:

Hello all,

I opened a PR to add a function which returns the broadcasted shape from a given set of shapes: https://github.com/numpy/numpy/pull/17535

As this is a proposed change to the API, I wanted to see if there was any feedback from the list.

Thanks, this is useful! I've implemented something similar many times over the years, and could have used it in some SciPy code, where we currently have a private implementation in one of the `stats` modules.

+1 for adding this.

There's a version of this helper function -- coincidentally with the exactly same API and name -- in JAX, too:
