title: error when connecting oracle in python using cx_Oracle
body: <p>I was trying to connect oracle database using python like below.</p>
  
  <pre><code>import cx_Oracle
  conn = cx_Oracle.connect('user/password@host:port/database')
  </code></pre>
  
  <p>I've faced an error when connecting oracle.
  DatabaseError: DPI-1047: 64-bit Oracle Client library cannot be loaded: "libclntsh.so: cannot open shared object file: No such file or directory". See <a href="https://oracle.github.io/odpi/doc/installation.html#linux" rel="nofollow noreferrer">https://oracle.github.io/odpi/doc/installation.html#linux</a> for help.</p>
  
  <p>I've been struggling to figure it out. I used my user name, password, host, port and database('orcl') for example,</p>
  
  <p><code>'admin/admin@10.10.10.10:1010/orcl'</code>.</p>
  
  <p>Why coudn't it connect? </p>
  
  <p>Ahh, btw I'm running all the code in azure notebooks.</p>
