Is this unavoidable for older pickle files?

not sure what you are pointing to. but you need to have an entry in pandas.compat/pickle_compat.py to handle the pickle compat

Thanks. I thought we had something like that.

There sure are a lot of people importing from pandas.core.categorical :/ https://github.com/search?q=from+pandas.core.categorical+import&type=Code&utf8=%E2%9C%93

I think I'll add a small future warning saying to use the public API.

Edit: oh A good chunk of that is people just uploading their entire site-packages to github :/

you could add a deprecating module (e.g. like tslib.py) in the to-level to make a nice transition

This looks pretty benign to me (I'm assuming there weren't any clandestine changes in the cut/paste).

I'd argue for calling it vectors instead of arrays so as to a) draw a clear distinction between the responsibilities of these objects vs np.array vs pd2 WIP and b) emphasize "FooVector is a vectorized version of FooScalar" (admittedly a motivation more specific to the arith/comparisons I've been focused on)

you prob need to change the paths in api.rst as well

no this is naming scheme is well-established

api.rst is all good. All the references via the public API.

not sure if you saw my comment above. I think you need a dummpy pandas.core.categorical.py which shows a FutureWarning.

@TomAugspurger

Yeah I have one. The diff is strange. The warning is at the top, and the import is at the bottom.

I c, ok. can you add a test for this (maybe in test_api), and add to the deprecations list. otherwise lgtm.

@TomAugspurger

Added a test.

Moved pandas.core.categorical to arrays.

Are we cool with merging PRs before the Mac build finishes? Travis had another outage, so they're backlogged again.

@TomAugspurger
Copy link
Contributor Author

I think I'm going to merge PRs that are unlikely to have issues specific to the Mac build. https://travis-ci.org/pandas-dev/pandas/builds/330306709 started 2.5 hours ago, and the Mac build hasn't been scheduled yet.

I'll do cleanup if I do break anything :)
