Windows Server 2016 python 3.6.6 albumentations version 0.1.8

Steps to reproduce the behavior: pip install imgaug (or pip install albumentations )

The error is probably due to missing C compiler required for building the dll. Workaround:

1. install binaries from https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely
2. conda install shapely pip install imgaug

Also solved it by direclty installing shapely from conda, without having to install any binaries beforehand.
