[jira] [Commented] (ARROW-7852) [Python] 0.16.0 wheels not
compatible with older numpy

A. Coady commented on ARROW-7852:
---------------------------------
This is still an issue with an existing numpy installed.

I think the setup `install_requires` needs to specify numpy>=1.16.

> 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.
