They mention implementing the model in TensorFlow, so it should absolutely be possible. (Unless they are using a special Google-only version.) One thing that might make reproduction difficult is that they don't describe their initialization procedure. But maybe it just doesn't matter.

Initialization is random according to abstract.

Yes, but random according to what distribution?
