{{When trying to get a numpy array of strings from pyarrow.StringArray type, a numpy array of }}{{dtype=object}}{{ is returned. Tried both Python 3.5 and 2.7.}} {{To reproduce:}} {{{{pa.StringArray.from_buffers(1, pa.py_buffer(b'\x00\x00\x00\x00\x05\x00\x00\x00'), pa.py_buffer(b'hello')).to_pandas()}}}} {{Result:}} {{Out[27]: array(['hello'], dtype=object)}} {{I would expect the result to be:}} {{array([b'hello'], dtype='|S5')}} {{(or '|U5' ?)}} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
