Neal Richardson commented on ARROW-10126:
-----------------------------------------

I have limited experience here (and zero experience with conda on windows) but 
I've found that you can't really mix conda and non-conda, and even within 
conda, if you're using pyarrow and r-arrow, they need to be on the same version 
because they have to share arrow-cpp. So either go all conda, including R 
itself, r-arrow, and pyarrow, or don't use conda at all and use a pyarrow wheel 
in a virtualenv.

> [Python] Impossible to import pyarrow module in python. Generates this 
> "ImportError: DLL load failed: The specified procedure could not be found."
