title: AttributeError: module 'numpy' has no attribute 'core'
body: <p>I was wondering if anyone had this issue when running spark and trying to import numpy. Numpy imports properly in a standard notebook, but when I try importing it via a notebook running spark, I get this error. I have the most recent version of numpy and am running the most recent anaconda python 3.6.</p>
  
  <p>Thanks!</p>
