title: How to save Confusion Matrix plot so that I can call it for future reference?
body: <p>I was using this latest function, sklearn.metrics.plot_confusion_matrix to plot my confusion matrix.</p>
  <pre><code>cm = plot_confusion_matrix(classifier,X , y_true,cmap=plt.cm.Greens)
  </code></pre>
  <p>And when I execute that cell, the confusion matrix plot showed up as expected. My problem is I want to use the plot for another cell later. When I called cm in another cell, it only shows the location of that object.</p>
  <pre><code>&gt;&gt;&gt; cm
  &gt;&gt;&gt; &lt;sklearn.metrics._plot.confusion_matrix.ConfusionMatrixDisplay at 0x1af790ac6a0&gt;
  </code></pre>
  <p>Calling <code>plt.show()</code> doesn't work either</p>
