When the first slide of a presentation contains code which should show line numbers it doesn't work. The line numbers are simply not shown.
When switching then from this first slide to another slide and back, the line numbers are there.

See a minimal example below:

<html>
  <head>
    <link rel="stylesheet" href="css/reveal.css">
    <link rel="stylesheet" href="css/theme/simple.css">
    <link rel="stylesheet" href="lib/css/zenburn.css">
  </head>
  <body>
    <div class="reveal">
      <div class="slides">
        <section>
          <pre><code class="python line-numbers">
print("hello world")
print("see, no line numbers")
          </code></pre>
        </section>
        <section>
          Slide 2
        </section>
      </div>
    </div>
    <script src="lib/js/head.min.js"></script>
    <script src="js/reveal.js"></script>
    <script>
      Reveal.initialize({
        dependencies: [
          { src: 'lib/js/classList.js', condition: function() { return !document.body.classList; } },
          { src: 'plugin/highlight/highlight.js', async: true, callback: function() { hljs.initHighlightingOnLoad(); } },
          { src: 'plugin/line-numbers/line-numbers.js', async: false}
        ]
      });
    </script>
  </body>
</html>

Actually it doesn't even have to be the first slide of a presentation, but the first loaded slide is sufficient. So the issue is visible in the sample presentation as well, when using a deep link: https://mikemiles86.github.io/reveal-line-numbers/#/3
