re><p>In scenarios where you do not need to setup the graph independently,
the session will create one for you.  The following example shows how
to abuse TensorFlow to compute the addition of two numbers:</p>
<pre><code class="lang-csharp">using (var session = new TFSession())
{
    var graph = session.Graph;

    var a = graph.Const(2);
    var b = graph.Const(3);
    Console.WriteLine(&quot;a=2 b=3&quot;);

    // Add two constants
    var addingResults = session.GetRunner().Run(graph.Add(a, b));
    var
