title: Multi Label classification with Sklearn
body: <p>I have tried using the OneVsRest with Logistic Regression from Sklearn, but it gives empty labels for some samples (i.e. doesn't predict any out), even though I do not have any unlabelled training data. </p>
  
  <p>Any idea what might be causing this or how to fix this?</p>
  
  <pre><code>clf = OneVsRestClassifier(LogisticRegression(multi_class='ovr',max_iter=1000,solver='lbfgs'))
  clf.fit(X,Y)
  self.classifier=clf
  
  
  self.classifier.predict(test_data)
  </code></pre>
