title: (Python (analysis)) Unable to resolve 'pandas'. IntelliSense may be missing for this module
body: <p>I am working on a python app in Visual Studio Code and would like to import <code>pandas</code>, <code>sqlalchemy</code>, and <code>flask</code> libraries.  However, when I enter code such as</p>
  
  <pre><code>    import pandas as pd
      import sqlalchemy
  </code></pre>
  
  <p>I get the error <code>[Python (analysis)] Unable to resolve 'pandas'. IntelliSense may be missing for this module</code><br>
  Likewise with sqlalchemy.  </p>
  
  <p>I checked the version of pandas in the command line by</p>
  
  <pre><code>    pip3 install --upgrade pandas
  </code></pre>
  
  <p>and it returns "<code>Requirement already up-to-date</code>".  </p>
  
  <p>So I am not sure what the issue is.  Any suggestions? Many thanks.</p>
