Tom Augspurger created ARROW-1586: ------------------------------------- Summary: [PYTHON] serialize_pandas roundtrip loses columns name Key: ARROW-1586 URL: https://issues.apache.org/jira/browse/ARROW-1586 Project: Apache Arrow Issue Type: Bug Components: Python Affects Versions: 0.7.0 Reporter: Tom Augspurger Priority: Minor Fix For: 0.8.0
The serialize / deserialize roundtrip loses {{ df.columns.name }} {code:python} In [1]: import pandas as pd In [2]: import pyarrow as pa In [3]: df = pd.DataFrame([[1, 2]], columns=pd.Index(['a', 'b'], name='col_name')) In [4]: df.columns.name Out[4]: 'col_name' In [5]: pa.deserialize_pandas(pa.serialize_pandas(df)).columns.name {code} Is this in scope for pyarrow? I suspect it would require an update to the pandas section of the Schema metadata. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
