> [Python] `np.float` deprecation warning in `_pandas_logical_type_map`
> ---------------------------------------------------------------------
>
> Key: ARROW-11010
> URL: https://issues.apache.org/jira/browse/ARROW-11010
> Project: Apache Arrow
> Issue Type: Task
> Reporter: Tim Swast
> Priority: Minor
> Fix For: 3.0.0
>
>
> I get the following warning when converting a floating point column in a
> pandas dataframe into a pyarrow array:
>
> ```
> /Users/swast/src/python-bigquery/.nox/prerelease_deps/lib/python3.8/site-packages/pyarrow/pandas_compat.py:1031:
> DeprecationWarning: `np.float` is a deprecated alias for the builtin
> `float`. Use `float` by itself, which is identical in behavior, to silence
> this warning. If you specifically wanted the numpy scalar type, use
> `np.float_` here.
> 'floating': np.float,
> ```
