------------------------------------------------------------------
IIUC, there is already a paragraph to suggest installing Visual C++
Redistribute at
[here|https://arrow.apache.org/docs/python/install.html#using-pip]? Do we need
to update the link and add an example for a failure?
{code}
If you encounter any importing issues of the pip wheels on Windows, you may
need to install the Visual C++ Redistributable for Visual Studio 2015.
{code}
Finally (beyond 0.15?), is it the best solution to bundle the DLLs? Since I am
studying how to package whl in windows for the release, it takes a time for me
to find a way to bundle the DLLs. If there is a document, it helps me.
