body: <p>I tried using Pandas for Ubuntu 16.04.6 LTS (GNU/Linux 4.4.0-173-generic x86_64) (Server).I want it for Python2.7.I tried <code>sudo pip install pandas</code> and <code>sudo apt-get install python-pandas</code>,<code>pip install --upgrade --force-reinstall pandas</code> it is getting installed,but when I try to use it in my Odoo's(ERP) Code,it is showing the error <code>No module named pandas</code></p>
  
  <p>After <code>sudo apt-get install python-pandas</code> it is showing :</p>

  <p>Thanks in advance.</p>
  
  <p><strong>EDIT</strong> :Now Server for this instance has been changed and I think now packages has been installed in a virtual env.
  I tried installing pandas in virtual env,but is showing permission issues.
  Ways Tried:</p>
  
  <pre class="lang-none prettyprint-override"><code>(venv) abc@erp:/opt/odoo10/abcuat/venv/bin$ pip install pandas
  </code></pre>
  
  <p>Error : </p>
  
  <pre class="lang-none prettyprint-override"><code>Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/opt/odoo10/techyslive/venv/lib/python2.7/site-packages/numpy'
  Consider using the `--user` option or check the permissions.
  </code></pre>
  
  <p>I tried using : <code>pip install pandas --user</code>
  Then this error : </p>
  
  <pre class="lang-none prettyprint-override"><code>DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.
  Can not perform a '--user' install. User site-packages are not visible in this virtualenv.
  You are using pip version 19.0.3, however version 20.0.2 is available.
  You should consider upgrading via the 'pip install --upgrade pip' command.
  </code></pre>
  
  <p>I also repeated these same steps with <code>pip2.7 install pandas</code>,<code>pip2 install pandas</code> etc.
  Please help</p>
