------------------------------
External issue URL: https://github.com/apache/arrow/issues/16735
> [Python] pyarrow needs to depend on numpy>=1.10 (not 1.9)
> ---------------------------------------------------------
>
> Key: ARROW-1124
> URL: https://issues.apache.org/jira/browse/ARROW-1124
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.4.1
> Reporter: Dima Ryazanov
> Assignee: Uwe Korn
> Priority: Minor
> Fix For: 0.5.0
>
>
> The pyarrow package lists numpy >= 1.9 as a dependency in setup.py - however,
> it causes an exception at import time with numpy 1.9.
> Repro steps:
> {{$ pip install numpy==1.9
> ...
> $ pip install pyarrow
> ...
> $ python -c 'import pyarrow'
> RuntimeError: module compiled against API version a but this version of numpy
> is 9
> Traceback (most recent call last):
> File "<string>", line 1, in <module>
> File
> "/home/dima/envs/pyarrow-bug/lib/python2.7/site-packages/pyarrow/__init__.py",
> line 28, in <module>
> from pyarrow.lib import cpu_count, set_cpu_count
> File "pyarrow/lib.pyx", line 40, in init pyarrow.lib
> (/arrow/python/build/temp.linux-x86_64-2.7/lib.cxx:62119)
> ImportError: numpy.core.multiarray failed to import
> }}
> (Additionally, requirements.txt lists "numpy>=1.7" - though it doesn't look
> like it's used at all.)
