title: How to make tensorflow-serving example work
body: <p>I am trying out the tensorflow example from the tutorial <a href="https://www.tensorflow.org/tfx/serving/docker" rel="nofollow noreferrer">page</a></p>
  <p>at the third step</p>
  <pre><code># Start TensorFlow Serving container and open the REST API port
  docker run -t --rm -p 8501:8501 \
  -v &quot;$TESTDATA/saved_model_half_plus_two_cpu:/models/half_plus_two&quot; \
  -e MODEL_NAME=half_plus_two \
  tensorflow/serving &amp;
  </code></pre>
  <p>I get the following error message
  2020-07-19 11:54:52.858203: E tensorflow_serving/sources/storage_path/file_system_storage_path_source.cc:362] FileSystemStoragePathSource encountered a filesystem access error: /models/half_plus_two; Permission denied</p>
  <p>This is continuously repeated. I have installed the demo model as mentioned in the tutorial.</p>
  <pre><code>git clone https://github.com/tensorflow/serving
  TESTDATA=&quot;$(pwd)/serving/tensorflow_serving/servables/tensorflow/testdata&quot;
  </code></pre>
  <p>Can someone please help what am i missing? I am just starting off on the serving part.</p>
  <p>Thanks</p>
