Description

When installing pyarrow 0.14.1 on windows 10 x64 with python 3.7, you get:

>>> import pyarrow
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python37\lib\site-packages\pyarrow_init_.py", line 49, in <module>
    from pyarrow.lib import cpu_count, set_cpu_count
  ImportError: DLL load failed: The specified module could not be found.

On 0.14.0 everything works fine.
