Tensorflow Backend - Bug in "model._make_predict_function"

Question

there's is a bug while running the Tensorflow code, the error code appears like this:

Traceback (most recent call last):
  File "app.py", line 76, in <module>
    model = deepmoji_emojis(maxlen, PRETRAINED_PATH)
  File "/home/lifeofpy/LifeofPy/AI Photographer Project/Text-to-Color/deepmoji/model_def.py", line 35, in deepmoji_emojis
    model._make_predict_function()
AttributeError: 'Functional' object has no attribute '_make_predict_function

and the file app.py is like this:

# print('Loading model from {}.'.format(PRETRAINED_PATH))
model = deepmoji_emojis(maxlen, PRETRAINED_PATH)
model.summary()
model._make_predict_function()

I think the error message is occured by the function 'model._make_predict_function', I would appreciate any comments on this issue. Thanks!

what is deepmoji_emojis ? Maybe it doesn't give model but something different. — furas

@furas github.com/hon9g/Text-to-Color/blob/master/app.py it returns a model... — ChungHa

in what tutorial did you find _make_predict_function() ? I tried to find it with Google and it seems it was private function in Keras but probably it was removed from code. — furas

@furas yeah I tried to find _make_predict_function() too, but I wasn't able to find it. Maybe it was an old version of Keras code, and switched to another code. So I'm wondering if there's a new version of _make_predict_function() — ChungHa

Use: model.make_predict_function()

instead of: model._make_predict_function()

I tried to find _make_predict_function() with Google and it seems it was private function in old Keras in keras.engine.training.py but now Keras is part of tensorflow and function was removed from code. I can't find _make_predict_function() in tensorflow.keras.engine.training.py

Some old posts suggest to use model.predict() instead of model._make_predict_function() before threads but other posts suggest to duplicate model for every thread. But maybe new code in tensorflow resolved problem with running it in threads and maybe it doesn't need this function any more.
