title: How to extract the best parameters from <scipy.stats._distn_infrastructure.rv_frozen object at 0x7f37ccfcdd50>? How to interpret this output?
body: <p>I'm trying to run a GridSearchCV for find the out the best parameter. Parameter provided as</p>
  <pre><code>params_space = {'c1': [scipy.stats.expon(scale=0.5)],'c2': [scipy.stats.expon(scale=0.05)]}
  </code></pre>
  <p>After executing the grid search, when I print the best_params_ following is the output:</p>
  <pre><code>&quot; &quot; &quot;print(&quot;Best Params : &quot;, rs.best_params_,&quot;\n&quot;)
  
  Best Params :  {'c1': &lt;scipy.stats._distn_infrastructure.rv_frozen object at 0x7f37ccfcdd50&gt;, 'c2': &lt;scipy.stats._distn_infrastructure.rv_frozen object at 0x7f37ccfd8790&gt;} &quot; &quot; &quot;
  </code></pre>
  <p>How to extract the value of <strong>C1</strong> and <strong>C2</strong> as I need it for training my model?</p>
