title: Scikit-learn joblib/zlib error
body: <p>I ran into the following error when trying to load a .pkl file using joblib.</p>
  
  <pre><code>    self.name = joblib.load(
          os.path.join(BASE_DIR, '../relative/directory/%s.pkl' % name)
      )
  </code></pre>
  
  <p>The above code yields the following error.</p>
  
  <pre><code> File "/usr/local/lib/python2.7/dist-packages/sklearn/externals/joblib/numpy_pickle.py", line 68, in read_zfile
      data = zlib.decompress(file_handle.read(), 15, length)
  zlib.error: Error -3 while decompressing data: invalid distance too far back
  </code></pre>
  
  <p>Has anyone run into this issue before?</p>
