User may confused: why need to install pandas but I just want to using numpy ? So maybe give a certainly exceptions before here to tell users, numpy type will first convert pandas df in pyspark so pandas installed is required, like: ```python if not has_pandas: // warning or raised friendly exception from pyspark.sql.pandas.utils import require_minimum_pandas_version require_minimum_pandas_version() ``` or add a notes before here at least. -- This is an automated message from the Apache Git Service.
