Keras, TensorFlow : “TypeError: Cannot interpret feed_dict key as Tensor”

Question

I am trying to use keras fune-tuning to develop image classify applications. I deployed that application to a web server and the image classification is succeeded.

Answer 1

I found that there are a couple of workarounds, depending on various context:

1. Using clear_session() function:

   from keras import backend as K
   

   Then do following at the beginning or at the end of the function, after predicting all the data:

   K.clear_session()
   

2. Calling _make_predict_function():

   After you load your trained model call:

   model._make_predict_function()
   

   See explanation

3. Disable threading:

   If you are running django server use this command:

   python manage.py runserver --nothreading 
   

   For flask use this:

   flask run --without-threads
