title: Where to install a new module from when the module is deprecated in Python
body: <p>I'm currently working on some Python code, and when I try to run the code it spits an error message </p>
  
  <pre><code>C:\Users\marra\Anaconda3\lib\site-packages\sklearn\externals\six.py:31: 
  DeprecationWarning: The module is deprecated in version 0.21 
  and will be removed in version 0.23 since we've dropped support for Python 2.7. 
  Please rely on the official version of six (https://pypi.org/project/six/).
    "(https://pypi.org/project/six/).", DeprecationWarning)
  </code></pre>
  
  <p>I understand that "deprecated" means that it contains some old version of module that is no longer updated, and what's recommended to do is to replace the old version with an updated version. </p>
  
  <p>But the problem is that I don't know what to do to update it with a newer version. </p>
  
  <p>Will I need to install something via <code>Anaconda Prompt (Anaconda3)</code> with a command like <code>install XXXX</code>? 
  Or will I need to download something on a certain website? I've already visited the website of the URL shown in the error message <code>(https://pypi.org/project/six/)</code> and tried downloading the files that were shown when I clicked "download file" button there, but they were some files that I couldn't open after all. </p>
  
  <p>My OS is Windows 10. </p>
  
  <p>Any suggestion to fix this? </p>
