title: ModuleNotFoundError: No module named 'sklearn.linear_model._base'
body: <p>I am trying to load a model saved as a <code>.joblib</code> file. I have tried <code>pickle</code>, <code>sklearn.externals.joblib</code> and <code>joblib</code> itself. All the same error. Below is an example of what I am trying to do.</p>
  
  <pre><code> clf = joblib.load("linear_regression_model.joblib")
  </code></pre>
  
  <p>This model was made using <code>sklearn.linear_model.LinearRegression</code>. However, when I try to open this file, I get this error:</p>
  
  <pre><code>ModuleNotFoundError: No module named 'sklearn.linear_model._base'
  </code></pre>
