title: ImportError: cannot import name 'tree' for sklearn
body: <p>I've recently installed Scipy, Numpy and Scikit-learn by using pip, but when I run the program below </p>
  
  <pre><code>from sklearn import tree
  
  features = [[140, 1], [130, 1], [150, 1], [170, 1]] #input
  labels = [0, 0, 1, 1] #output
  
  clf = tree.DecisionTreeClassifier()  
  clf = clf.fit(features, labels) #fit = find patterns in data
  
  print (clf.predict([[160, 0]]))
  </code></pre>
  
  <p>The shell prints this error </p>
  
  <pre><code>Traceback (most recent call last):

    File "C:/Machine Learning\sklearn.py", line 1, in &lt;module&gt;
      from sklearn import tree

  <p>Does anyone know how to solve this? I've tried uninstalling and reinstalling it, but I get the same error. Many thanks in advance! </p>
