Bryan Cutler created ARROW-2101: ----------------------------------- Summary: [Python] from_pandas reads 'str' types as binary Arrow data with Python 2 Key: ARROW-2101 URL: https://issues.apache.org/jira/browse/ARROW-2101 Project: Apache Arrow Issue Type: Bug Components: Python Affects Versions: 0.8.0 Reporter: Bryan Cutler
Using Python 2, converting Pandas with 'str' data to Arrow results in Arrow data of binary type, even if the user supplies type information. conversion of 'unicode' type works to create Arrow data of string types. For example {code} In [25]: pa.Array.from_pandas(pd.Series(['a'])).type Out[25]: DataType(binary) In [26]: pa.Array.from_pandas(pd.Series(['a']), type=pa.string()).type Out[26]: DataType(binary) In [27]: pa.Array.from_pandas(pd.Series([u'a'])).type Out[27]: DataType(string) {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
