How to upgrade the classifier to the latest version of scikit-learn : <p>I have a big trained TfidfVectorizer dumped with <a href="https://pythonhosted.org/joblib/generated/joblib.dump.html" rel="noreferrer">joblib.dump</a>.
It was created on my laptop with scikit-learn version 0.18. When I'm trying to put it to my server where the newest version of scikit-learn 0.18.1 is installed I'm getting warned with the following:</p>

<pre><code>/usr/local/lib/python2.7/dist-packages/sklearn/base.py:315: UserWarning: Trying to unpickle estimator TfidfTransformer from version 0.18 when using version 0.18.1. This might lead to breaking code or invalid results. Use at your own risk.
  UserWarning)

</code></pre>

<p>Is there a natural way to upgrade my TfidfVectorizer to prevent any problems? </p>

<p>Should I better uninstall scikit-learn 0.18.1 and install version 0.18 to the server instead? </p>
