Description

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,

```
