Antoine Pitrou updated ARROW-1156:
----------------------------------
Component/s: Python
> [Python] pyarrow.Array.from_pandas should take a type parameter
> ---------------------------------------------------------------
>
> Key: ARROW-1156
> URL: https://issues.apache.org/jira/browse/ARROW-1156
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Python
> Affects Versions: 0.4.0
> Reporter: Wenchen Fan
> Assignee: Wes McKinney
> Priority: Major
> Fix For: 0.7.0
>
>
> It's convenient to infer the data type so that users can just write
> {{pyarrow.Array.from_pandas(arr)}}, however, sometimes users want
> fine-grained control, e.g., if we have an object type numpy array, whose
> values are all null. When we convert it to an arrow column vector, we may
> need a specific type instead of NullType.
