> Key: ARROW-8557
> URL: https://issues.apache.org/jira/browse/ARROW-8557
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.15.1, 0.16.0, 0.17.0
> Environment: Python 3.8.4, GCC 4.8.4, Debian 8
> Reporter: Hal T
> Priority: Major
>
> I have tried versions 0.15.1, 0.16.0, 0.17.0. Same error on all. I've seen in
> other issues that co-installations of tensorflow and numpy might be causing
> issues. I have tensorflow==1.14.0 and numpy==1.16.4 (and many other
> libraries, but I've read that those tend to cause issues)
