Dima Ryazanov updated ARROW-1554:
---------------------------------
Description:
I just tried pyarrow on Windows 10, and it fails to import for me:
```
>>> import pyarrow
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Program Files\Python36\lib\site-packages\pyarrow\__init__.py", line
32, in <module>
from pyarrow.lib import cpu_count, set_cpu_count
ImportError: DLL load failed: The specified module could not be found.
```
Not sure which DLL is failing, but I do see some DLLs in the pyarrow folder:
C:\Users\dima\Documents>dir "C:\Program
Files\Python36\lib\site-packages\pyarrow\"
Volume in drive C has no label.
Volume Serial Number is 4CE9-CC3C
Directory of C:\Program Files\Python36\lib\site-packages\pyarrow

09/19/2017 01:14 AM 604,160 arrow_python.dll
09/19/2017 01:14 AM 3,402 compat.py
...
However, I cannot open them using ctypes.cdll. I wonder if some dependency is
missing?
