title: How to install libjpeg?
body: <p>I tried these commands:</p>
  
  <pre><code>pip install libjpeg8-dev
  pip install libjpeg-dev
  pip install libjpeg-devel
  pip install libjpeg
  pip install libjpeg62 libjpeg62-dev
  </code></pre>
  
  <p>but none of them works. What is the right command with pip?</p>
