Is XLA enabled in 19.03-py2 ?

I see references to XLA in the output as follows :

TensorFlow in the NGC containers is build with support for XLA. Whether XLA is actually used to execute a given model depends on the specific model scripts. For more information see https://www.tensorflow.org/xla/jit
