is_categorical deprecated

[philip-khor]

Getting FutureWarning that is_categorical is deprecated. See pandas-dev/pandas#33385

Proposed Changes

• Change is_categorical() to is_categorical_dtype()

I don't mean to intrude, but I encountered this issue myself and would love to see this updated in the package :)

One word of caution though, simply replacing the call does break for users with pandas 1.0.x or below.
In case it is desired to keep support for pandas<1.1.0, call the appropriate method depending on the pandas version.
The cleanest way is probably to just check if the is_categorical_dtype function is present and fall back on is_categorical if not.

Hi! Is there an update on this?

[RoyalTS]

Is there any chance of this getting merged and of the package getting updated anytime soon? Would be happy to do the work if more work needs doing.

ignores = [
    ('category_encoders', FutureWarning, 'is_categorical is deprecated and will be removed in a future version.  Use is_categorical_dtype instead')
    # add addition warnings you want to ignore
]

for module, category, message in ignores:
    warnings.filterwarnings('ignore', module=module, category=category, message=message)

Hey all, working through some old PRs, this looks good. If you'd be interested in working to maintain the project more actively please check out #248, I'm (as you probably noticed) not able to consistently.
