title: ValueError: Failed to load delegate from libedgetpu.so.1 docker container
body: <p>I'm using ubuntu 18.04, on remote host that a coral is connected to.
  The docker container is taken from <a href="https://catalog.ngc.nvidia.com/orgs/nvidia/containers/tensorflow/tags" rel="nofollow noreferrer">https://catalog.ngc.nvidia.com/orgs/nvidia/containers/tensorflow/tags</a> (21.09-tf2-py3).
  I'm trying to get inferences from a TPU model, but stucked when initializing the TF Lite interpreter:</p>
  <pre><code>interpreter = pycoral.make_interpreter(model)
  </code></pre>
  <p>getting this error:</p>
  <pre><code>ValueError: Failed to load delegate from libedgetpu.so.1
  </code></pre>
  <p>I checked the connection to the coral, it's ok.
  I tried looking at the /dev/apex_0 but there is no such dir or file.
  Any suggestions?</p>
