title: In Jupyter, where is '/home/jovyan'?
body: <p>I don't know how to open a local file in Jupyter.Some answers say that I should change this workflow.</p>
  
  <p>so, I had tried this in Jupyter on Mac:</p>
  
  <p>In:</p>
  
  <pre><code>%pwd
  </code></pre>
  
  <p>Out:</p>
  
  <pre><code>'/home/jovyan'
  </code></pre>
  
  <p>In:</p>
  
  <pre><code>%cd /Users/apple/Desktop
  </code></pre>
  
  <p>Out:</p>
  
  <pre><code>[Errno 2] No such file or directory: '/Users/apple/Desktop'
  /home/jovyan
  </code></pre>
  
  <p>What's wrong?<br>
  And then, I can not find '/home/jovyan' on my Mac.</p>
