title: Python interpretor returns error for FASTAPI - **extra: Any,
body: <p>I'm having trouble executing fastapi under WSL.
  I'm using:</p>
  <ul>
  <li>WSL2</li>
  <li>Ubuntu 16.04.7 LTS</li>
  <li>Python 3.5.2 (using Visual Studio Code interpretor)</li>
  <li>fastapi - 0.73.0</li>
  <li>uvicorn - 0.8.6</li>
  </ul>
  <p>I'm getting an error when I execute the <code>uvicorn</code> command -</p>
  <blockquote>
  <p>**extra: Any,</p>
  </blockquote>
  <ul>
  <li>see attached image.</li>
  </ul>
  <p>I'm stuck on this for a while so any ideas would be strongly appreciated.</p>
  <p>I tried updating python interpretor to newer version (3.9) but for some reason I did not succeed - see pls the second attached screenshot.</p>
