RE example doesn't work

[zhaoli2017]

Hello, your examples for relation extraction don't work. Could you please check that?

What issue are you having ? have you changed the BASE_PRETRAINED_DIR to the public url described on README?

[zhaoli2017]

Yes, I changed the BASE_PRETRAINED_DIR. I can fine-tune and evaluate the model, however, there is an error when running 'model.predict'.

`/usr/local/lib/python3.7/dist-packages/mesh_tensorflow/transformer/utils.py in infer_model(estimator, vocabulary, sequence_length, batch_size, model_type, model_dir, eval_checkpoint_step, checkpoint_paths, decode_fn)
1853 batch_size=batch_size,
1854 sequence_length=sequence_length,
-> 1855 checkpoint_path=checkpoint_path)
