[jira] [Updated] (ARROW-7852) [Python] 0.16.0 wheels not compatible
with older numpy
[ https://issues.apache.org/jira/browse/ARROW-7852?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joris Van den Bossche updated ARROW-7852:
-----------------------------------------
Summary: [Python] 0.16.0 wheels not compatible with older numpy (was: Update pyarrow numpy requirement)
> [Python] 0.16.0 wheels not compatible with older numpy
> ------------------------------------------------------
>
> 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
> Priority: Minor
>
> 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.
