-------------------------------------
Summary: Update pyarrow numpy requirement
Key: ARROW-7852
URL: https://issues.apache.org/jira/browse/ARROW-7852
Project: Apache Arrow
Issue Type: Bug
Affects Versions: 0.16.0
Reporter: Stephanie Gott
Using python 3.7.5 and numpy 1.14.6, I am unable to import pyarrow 0.16.0 (see
below for error). Updating numpy to the most recent version fixes this, and I'm
wondering if pyarrow needs update its requirements.txt.
