google.protobuf.message.decodeerror error parsing message

[GermanInfinity]

This error comes when trying to load the model from stable_solve.py (attached below)
icml_paper_model.zip

Error comes from loading model like this:
with tf.io.gfile.GFile(pbFile, "rb") as f:
graph_def = tf.compat.v1.GraphDef()
graph_def.ParseFromString(f.read())

To successfully load the model; change the way the model is saved to:
with model.graph.as_default():
tf.train.write_graph(tf.get_default_graph(), "path-to-folder", 'saved_model.pb', as_text=False)
