Numpy and Common Lisp?

[Elliott Johnson]

Robert,I must say that I am a big fan of your work on asdf and in awe of your professional and academic career.I agree with your assessment that numpy and the entirety of NUMFocus would be well outside the scope of the current CL community.In an effort to conserve the momentum of this thread and channel the spirit of my time at Franz Inc, I'd like to emphasize that a lot can be accomplished by a small team with clear goals and roles.I hope that if a such project arises that I can be of assistance.Best regards,ElliottSent from my T-Mobile 5G Device

I don't mean to rain on the parade, but the development and maintenance of numpy consumes a level of resources that is simply beyond the capacity of the CL community to muster.
The NUMFocus project, a non-profit, supports this and other numerical computation projects (most, but not exclusively python), drawing on substantial amounts of corporate sponsorship.
I urge you to cast your eyes on this NumFOCUS sponsors list before thinking that our community could even begin to tackle this task:  https://numfocus.org/sponsors

There's also the Lisp-Stat ecosystem, if you don't already know about it. Data-frame, array-operations and LLA (Lisp Linear Algebra) cover much of numpy's functionality; at least enough to get significant work done.

FYI -  there appears to be a library called numcl that was written to cover numpy's functionality.

   https://github.com/numcl/numcl

I've yet to try it, but thought I'd pass along the link.

There’s cl-ana, which may be a useful substitute in some cases… or april, possibly.









cliki.net






cl-ana



















cliki.net






april












If you specifically want numpy, it may be possible to have Common Lisp talking to python.

Hi Michael

I am all for it.  But, as I said, I am an academic (and a cat).

Should we (as in "a bunch of common lispers", most of whom with day jobs) want to do something like that, how would you want to proceed?  Note that I have been part of many past failures.

All the best

Marco

IMHO, it'd be easier and effective to band up together and FIRST write a proper API specification and THEN implement it in CL.





I agree.  Here’s the API specification for NumPy: https://numpy.org/doc/stable/reference/index.html#reference

Looks rather intimidating. Less intimidating though, than doing the FFI dance, though.
