Constant

public final class Constant

An operator producing a constant value.

All endpoints of this operator are named `constant`, except those accepting vararg elements in parameter, which are named `array`. For example:

Ops tf = Ops.create();
 tf.constant(1.0f);  // mapped to Constant.scalarOf(scope, float);
 tf.constant(new float[] {1.0f, 2.0f);  // mapped to Constant.vectorOf(scope, float[])
 tf.constant(new float[][] { {1.0f, 2.0f}, {3.0f, 4.0f} });  //mapped to Constant.tensorOf(scope, float[][])
 tf.array(1.0f, 2.0f, 3.0f);  // mapped to Constant.arrayOf(scope, float...)
 }
