title: Can only run my copy_files.py from one directory
body: <p>I can run my <code>copy_files.py</code> script from only one directory.
  When I run it from other directories, I get the following errors:</p>

  <p>I have tried to remove all of the script's body, even renamed the script.</p>
  
  <pre><code>#!/usr/local/bin/python3.6
  
  import sys
  sys.path.insert(0, "/usr/local/lib/python3.6/site-packages")
  import cx_Oracle
  import glob
  import os
  import time
  import paramiko
  from scp import SCPClient
  
  cli = paramiko.client.SSHClient()
  cli.set_missing_host_key_policy(paramiko.client.AutoAddPolicy())
  </code></pre>
  
  <p>I expect the script to establish a connection, and it just errors.
  I run the script from the first directory it ran from $MDS_SRC/ and it runs fine.
  I can copy the entire script to my local directory , and it errors out.</p>
