title: Python 3 - ModuleNotFoundError: No module named 'xgboost'
body: <p>I am a total newbie in Python 3 and programming in general so I looked at other peoples code and just for the beginning paste one example into Jupyter. But right at the beginning, I get an Error "ModuleNotFoundError: No module named 'xgboost'" Why does this not work? </p>
  
  <pre><code>import pandas            as pd
  import numpy             as np
  import re
  import sklearn
  import xgboost           as xgb // error
  import seaborn           as sns
  import matplotlib.pyplot as plt
  
  %matplotlib inline
  
  import plotly.offline    as py
  py.init_notebook_mode(connected=True)
  import plotly.graph_objs as go
  import plotly.tools      as tls
  
  import warnings
  warnings.filterwarnings('ignore')
  
  # Going to use these 5 base models for the stacking
  from sklearn.ensemble         import (RandomForestClassifier, AdaBoostClassifier, GradientBoostingClassifier, ExtraTreesClassifier)
  from sklearn.svm              import SVC
  from sklearn.cross_validation import KFold
