I ran into an issue a few days ago and found out something that may be affecting many GraphLab users who use it with Anaconda on Windows. NumPy was unable to load, and consequently everything that requires it (Matplotlib etc).
It turns out that the current NumPy build (1.10.4) for Windows is problematic (more info here).
Possible workarounds are downgrading to build 1.10.1 or forcing an upgrade to 1.11.0 if your dependencies allow. Downgrading was easy for me using
conda install numpy=1.10.1
Thanks for your attention!
