title: Bus error (core dumped) due to Permission changes
body: <p>The following error occurs due to change in permission in a jupyter environment: It occurs irrespective of execution of a python script or other execution operation with userX.</p>
  
  <pre><code> Bus error (core dumped)
  </code></pre>
  
  <p>Note: <strong>While working with root it works fine</strong>.</p>
  
  <p>I remember changing permissions, mainly <code>chmod 755 /</code> and also <code>chmod -R 755 /home/userX</code> with root access.</p>
  
  <p>I guess changing or revoking the file permission should work. But I am unable to figure out. Any help would be much appreciated :)</p>
