Antoine Pitrou commented on ARROW-2093:
---------------------------------------

Also note the builds we're fetching don't seem to work (or not always?):
{code}
SKIP [1] 
/home/travis/build/apache/arrow/pyarrow-test-2.7/lib/python2.7/site-packages/pyarrow/tests/test_serialization.py:353:
 could not import 'torch'
{code}

Tried to reproduce locally:
{code}
$ python -c "import torch"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File 
"/home/antoine/miniconda3/envs/ttt/lib/python3.6/site-packages/torch/__init__.py",

    from torch._C import *
ImportError:
