Is it thread-safe when using tf.Session in inference service?
<p>Now we have used TensorFlow to train and export an model. We can implement the inference service with this model just like how <code>tensorflow/serving</code> does.</p>

<p>I have a question about whether the <code>tf.Session</code> object is thread-safe or not. If it's true, we may initialize the object after starting and use the singleton object to process the concurrent requests.</p>
