   I would modify src/neuralnets.py to use keras.models.load_model and save_model as *.hdf5 files, not *.json files.

   The problem with saving as json is there is not a function to load a json into a model with weights.

   I am able to load and save models as *.hdf5 files. Everything seems to run correctly, but when using the models to predict an emotion, I'm not getting correct answers.

   Also, copy over the predict function from FERModel

   Did you use 64x64 images or 48x48? I changed to 48x48

   I had the exact same problem as Octo - i just used the precoded "convolutional_model.py" example, and wanted to try this newly trained model on the provided images. I tried to change the "export_model" as Daniel suggested. And just like Daniel, i can now load my model in fermodel.py by using the constructor FERModel(...). But when i try to predict with this model, i get the following results:

   anger: nan%
   happiness: nan%
   surprise: nan%
   

   Can anyone help me with this? I've changed the export_model to:

   def export_model(self, model_filepath, weights_filepath, emotion_map_filepath, emotion_map):
           self.model.save_weights(weights_filepath)
           self.model.save(model_filepath) #My addition
           
           // And the out-commented this
           //model_json_string = self.model.to_json()
           //model_json_file = open(model_filepath, 'w')
           //model_json_file.write(model_json_string)
           //model_json_file.close()
           
   
           with open(emotion_map_filepath, 'w') as fp:
               json.dump(emotion_map, fp)
   

   I don't know if it has anything to do with all the warnings coming from executing your code:

   @heshe Thank you for your comment. I can't answer your question, but for readability, could you please encapsulate the console logs in code syntax. It's going to be easier to read. Thank you.
