Update keras, tf and new model usage, numpy 2.0 updates by JGSweets · Pull Request #1206 · capitalone/DataProfiler

JGSweets · 2026-03-13T22:13:54Z

this pr:

updates to allow keras usage > 3.4
allows usage of most recent TFs / metal instead of macos
Updates numpy for v2+

NOTES:

built off of refactor: move from deprecated pkg_resources #1202 and will need to rebase once that merges

JGSweets · 2026-05-06T19:56:44Z

        :param fn: Plugin function
        :return: function
        """
-        global plugins_dict


global is only needed when a function rebinds a module variable, like plugins_dict = {...}.

JGSweets · 2026-05-06T20:01:45Z

@shania-m this is the final PR that will update TF and keras to be current!

JGSweets · 2026-05-11T18:08:44Z

@shania-m I've updated numpy to allow for 2.0+ as well here!

shania-m · 2026-05-11T19:03:33Z

@JGSweets please let me know when it’s ready for review

JGSweets · 2026-05-11T20:21:24Z

@shania-m fixed all the issues related. Updating mypy was more complicated than expected when trying to handle the numpy update!

@shania-m sorry to add so much more, but this should be safer since it has the dict mapping back!

shania-m · 2026-05-22T17:36:35Z

Thanks for the contributions!
Some non blocking recommendations:

Add an upper bound to numpy — numpy>=1.22.0,<3.0.0 instead of numpy>=1.0.0 to prevent future breakage from numpy 3.
Add an upper bound to keras — keras>3.4.0,<4.0.0 to protect against future Keras major versions.
Add a test for loading old-format models — Verify that _normalize_model_outputs correctly handles models saved with the previous list-style
output format.
Track numpy private API usage — Add a code comment noting that _histograms_impl is a private module, linking to any numpy discussion about a public replacement.
Update CHANGELOG — Document the numpy 2.0 and keras >3.4 support as a notable change.

JGSweets · 2026-05-22T19:45:02Z

Updated.
Updated.
Added unit tests to address this.
Added a comment.
Added a CHANGELOG

Thanks!

@JGSweets i need to review these before approving

JGSweets · 2026-05-22T20:32:47Z

@shania-m of course! ty for working with me on this!

JGSweets · 2026-05-22T20:40:18Z

After this goes in, what would be the steps needed to make a release? I assume I cannot be part of that, but if so I'm happy to help achieve that as well!

JGSweets · 2026-05-28T16:23:14Z

I realized it might also be good to add py3.12 / py3.13 to the test list, especially since py3.10 reaches EOL this fall.

Will do that in a subsequent PR.

JGSweets · 2026-06-01T14:12:01Z

@shania-m any updates on the license review?

@shania-m any updates on the license review?

Hi! I’m still working on this

JGSweets · 2026-06-03T15:27:38Z

Awesome @shania-m, Looking forward to this getting through! Like I mentioned, I'd probably follow-up with py3.12, py3.13 test additions to make sure it is forward functional and then figure out with you how to do a release!

Thanks again for all this help!
