title: ImportError: No module named numpy - Google Cloud Dataproc when using Jupyter Notebook
body: <p>When starting Jupyter Notebook on Google Dataproc, importing modules fails. I have tried to install the modules using different commands. Some examples:</p>
  
  <pre><code>import os
  os.sytem("sudo apt-get install python-numpy")
  os.system("sudo pip install numpy") #after having installed pip
  os.system("sudo pip install python-numpy") #after having installed pip
  
  import numpy
  </code></pre>
  
  <p>None of the above examples work and return an import error:</p>

  <p>When using command line I am able to install modules, but still the import error remains. I guess I am installing modules in a wrong location.</p>
  
  <p>Any thoughts?</p>
