title: Error while loading pkl file using joblib
body: <p>Following <a href="https://github.com/adithyaselv/face-expression-detect/blob/master/EmoDetect.py" rel="nofollow noreferrer">this</a> post, I'm trying to execute the code using joblib. But I'm getting the following error:</p>
  
  <pre><code>classify=joblib.load("traindata.pkl")
  </code></pre>
  
  <blockquote>
    <p>ValueError: You may be trying to read with python 3 a joblib pickle
    generated with python 2. This feature is not supported by joblib.</p>
  </blockquote>
  
  <p>In the <a href="https://github.com/scikit-learn/scikit-learn/blob/master/sklearn/externals/joblib/numpy_pickle.py" rel="nofollow noreferrer">doc</a>, it's saying I'm using python3, that's why getting this error.</p>
  
  <p>How to read the pkl file using python3? </p>
  
  <p>Thank you!</p>
