title: import numpy suddenly stopped working on Jupyter notebook (ImportError: cannot import name 'add_newdocs')
body: <p>I am realtively new to jupyter. I have windows 10 whereby I installed anaconda and simply followed the instruction to download python 3 for jupyter notebook. I enjoy it and started drawing figures and so on but suddenly something happend and jupyter can not import numpy any more </p>
  
  <pre><code>import numpy
  </code></pre>
  
  <p>now gives me the following </p>
  
  <pre><code>---------------------------------------------------------------------------
