title: python script not starting with etc/rc.local
body: <p>I created a python script that I would like to execute at each startup. I modified the <code>etc/rc.local</code>, but I don't get the script to run.</p>
  
  <p><code>etc/rc.local</code> addition (I added the sleep thinking it may help):</p>
  
  <pre><code>(sleep 10; /usr/bin/python3 /home/pi/mower-gps-tracking/app/gps_logger.py)&amp;
  </code></pre>
  
  <p>imports in the different python scripts (I don't know if it matters):</p>
  
  <pre><code>from ftplib import FTP
  import os
  import serial
  import time
  import threading
  from gpiozero import LED, Button
  </code></pre>
  
  <p>When I start the <code>etc/rc.local</code> manually via a <code>ssh</code> command, it runs fine.</p>
  
  <p>Any idea what I'm missing ?</p>
