The code comes from https://github.com/freesunshine0316/neural-graph-to-seq-mp of paper A Graph-to-Sequence Model for AMR-to-Text Generation in ACL 2018
The code is developed under TensorFlow 1.4.1. We shared our pretrained model along this repository. Due to the compitibility reason of TensorFlow, it may not be loaded by some lower version (such as 1.0.0).
