Wes McKinney commented on ARROW-2131:
-------------------------------------
One workaround for this is to run {{setup.py develop}}. Either way the instructions in https://github.com/apache/arrow/blob/master/python/doc/source/development.rst may lead to test failure for Windows developers at the moment
> [Python] Serialization test fails on Windows when library has been built in place / not installed
