Session

Driver for Graph execution.

A Session instance encapsulates the environment in which Operation s in a Graph are executed to compute Tensors . For example:

// Let's say graph is an instance of the Graph class
 // for the computation y = 3 * x

 try (Session s = new Session(graph)) {
   try (Tensor x = Tensor.create(2.0f);
       Tensor y = s.runner().feed("x", x).fetch("y").run().get(0)) {
       System.out.println(y.floatValue());  // Will print 6.0f
   
   try (Tensor x = Tensor.create(1.1f);
       Tensor y = s.runner().feed("x", x).fetch("y").run().get(0)) {
       System.out.println(y.floatValue());  // Will print 3.3f
   }
 }
 }

WARNING: A Session owns resources that must be explicitly freed by invoking close() .

Instances of a Session are thread-safe.
