[jira] [Created] (ARROW-1156) pyarrow.Array.from_pandas should take a type parameter

Wenchen Fan created ARROW-1156:
----------------------------------

             Summary: 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
    Affects Versions: 0.4.0
            Reporter: Wenchen Fan


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.
