Code PR

  • I have read through the contributing notes and understand the structure of the package. In particular, if my PR modifies code of plotly.graph_objects, my modifications concern the codegen files and not generated files.
  • I have added tests (if submitting a new feature or correcting a bug) or
    modified existing tests.
  • For a new feature, I have added documentation examples in an existing or
    new tutorial notebook (please see the doc checklist as well).
  • I have added a CHANGELOG entry if fixing/changing/adding anything substantial.
  • For a new feature or a change in behaviour, I have updated the relevant docstrings in the code to describe the feature or behaviour (please see the doc checklist as well).

Close #4102

Sorry, something went wrong.

@nicolaskruchten As Pandas 2 is already in the RC phase with a final release expected in the next weeks, it would be nice to see this in the next release. The change is backwards compatible.

Thanks @kaibir - and @aberres I agree, would be great to get this in ASAP, and we'll be working to make a release in the next day or two. What I'd love to do before we merge this though is add a test job (or two I guess, get both _core and _optional) that uses pandas 2 on Py3.11, and see if it surfaces any other issues. I think would just need to be two new jobs in https://github.com/plotly/plotly.py/blob/master/.circleci/config.yml plus two new requirements files in https://github.com/plotly/plotly.py/tree/master/packages/python/plotly/test_requirements - if either of you would be able to give that a go it would be a big help, otherwise we can try to get to it before we need to make the next release.

@alexcjohnson We can give it a try.

As I see things, the currently used images were deprecated, and there is now cimg/python. My feeling is this switch should be made in a different PR.

As Pandas happily works with 3.9 (the newest Python version checked right now), maybe we should start adding another _optional with Pandas 2 based on python_39_optional for starters?

@alexcjohnson Python 2.0 forbids creating float16 indxes:

The easiest thing to do would be to drop this line here.

Maybe a question for @nicolaskruchten as much as for you @kaibir - since there are already other examples of these exclusions in other kinds, but how do we know what needs to be excluded?

yeah in principle the Pandas team isn't meant to add kwargs or mess with that API much any more but if/when they do (by e.g. adding upstream kwargs) then our tests will fail.

💃 This looks great @kaibir @aberres - thanks for adding the new test run! And apologies for the delay, I was OOO for the last 2 weeks.

My comment is more for my own info than blocking.

Thanks for the quick release @LiamConnors @alexcjohnson.

I think #4145 should also be solved by this.
