What's the right way of using the decode_word in other modules

[bobzsj87]

Hi,

I am trying to load G2PModel instance which is to be shared by other applications (e.g. an HTTP server). When I tried to use the model.decode_word, it says res_iter is not in the model. Until I manually run interactive() or run the private method._G2PModel__prepare_interactive_model() could everything be initialized. Then run the decode_word for the first time. After that, each word decode is lightning fast.

What's the clean way of getting everything initialized and use the model to decode_word from the application?

I added the following method in the app.py, so it will return an initialized model, which can be cached and reused in decode_word

`
def standalone_model(model_dir):
if not model_dir:
raise RuntimeError("Model directory not specified.")

params = Params(model_dir, '')
params.hparams = g2p_trainer_utils.load_params(model_dir)
model = G2PModel(params)

model.inputs = [] # initialization
model._G2PModel__prepare_interactive_model()
model.decode_word('apple') # run for the first time
return model
`
