title: Clear cached images in Jupyter Notebook
body: <p>I have a jupyter notebook that creates a local cache of images.  I would like to clear the cache before I run a particular cell.  Does anyone know how to do that?  I tried:</p>
  
  <pre><code>import gc
  gc.collect()
  </code></pre>
  
  <p>But it had no effect.  I also tried clear all the cookies and cache in chrome, but that did work either.</p>
