title: OSError when trying to run XGBoost on Jupyter Notebook
body: <p>I installed xgboost through pip and am trying to run it on Jupyter Notebook.
  However, when running</p>
  
  <pre><code>from xgboost import XGBClassifier
  </code></pre>
  
  <p>on a Python 3 jupyter notebook, I get the following error:</p>
  
  <pre><code>OSError: /home/martin/anaconda3/bin/../lib/libgomp.so.1: version GOMP_4.0' not found (required by /home/martin/anaconda3/lib/python3.6/site-packages/xgboost/./lib/libxgboost.so)
