Wes McKinney created ARROW-4308:
-----------------------------------
Summary: [Python] pyarrow has a hard dependency on pandas
Key: ARROW-4308
URL: https://issues.apache.org/jira/browse/ARROW-4308
Project: Apache Arrow
Issue Type: Bug
Components: Python
Reporter: Wes McKinney
Fix For: 0.13.0
We either need to make pandas a soft dependency (as it was in the past) or add
it to the package requirements. Calling {{pip install pyarrow}} for 0.12.0 in a
fresh environment results in
{code}
In [1]: import pyarrow as pa
