title: Run openface docker container on Heroku
body: <p>I'm trying to deploy <a href="https://hub.docker.com/r/bamos/openface/" rel="nofollow noreferrer">https://hub.docker.com/r/bamos/openface/</a> image to Heroku, so I downloaded the code from <a href="https://github.com/cmusatyalab/openface" rel="nofollow noreferrer">https://github.com/cmusatyalab/openface</a> and followed those steps <a href="https://devcenter.heroku.com/articles/container-registry-and-runtime" rel="nofollow noreferrer">https://devcenter.heroku.com/articles/container-registry-and-runtime</a>.</p>
  
  <p>The push and release seems to be working, but when I try accessing the app url, I get this error why inspecting via <code>heroku logs --tail</code>:</p>
  
  <pre><code>Traceback (most recent call last):
  File "./demos/web/websocket-server.py", line 22, in &lt;module&gt;
  import txaio
  ImportError: No module named txaio
  </code></pre>
  
  <p>So I tried adding <code>txaio &gt;= 2.10.0</code> to the <code>requirements.txt</code>, but nothing changed.</p>
  
  <p>What else can I try? Am I doing something wrong?</p>
