Keras Sequential Model-SGD- Neural Network-NLTK

问题

creating a bot, Here i faced error after training. i trained using the Keras SEQUENTIAL Model, SGD Optimizer, NLTK

lemmatizer =WordNetLemmatizer()
words =pickle.load(open("words.pkl",'rb'))# reading binary mode
classes= pickle.load(open("classes.pkl",'rb'))
model =load_model('chatbot.model')
print(classes)

def clean_up_sentence(sentence):
  sentence_words =nltk.word_tokenize(sentence)
  sentence_words=[lemmatizer.lemmatize(word) for word in sentence_words]
return sentence_words

def bag_of_words(sentence):
   sentence_words = clean_up_sentence(sentence)
   bag=[0]*len(words)
   for w in sentence_words:
     for i, word in enumerate(words):
       if word == w:
         bag[i]=1
 return np.array(bag)

 def predict_class(sentence):
   bow = bag_of_words(sentence)
   res = model.predict(np.array([bow]))[0]
   ERROR_THRESHOLD =0.25
   results=[[i,r] for i, r in enumerate(res) if r > ERROR_THRESHOLD]

   results.sort(key =lambda x: x[1], reverse=True)
 return_list=[]
 for r in results:
   return_list.append({'intent':classes[r[0]], 'probability':str(r[i])})
 return return_list

def get_response(intents_list, intents_record):
  tag = intents_list[0]['intent']
  list_of_intents =intents_record['intents']
  for i in list_of_intents:
    if i['tag']==tag:
  result =random.choice(i['responses'])
  break
return result

print("READY TO GO, BOT RUNNING......")

while True:

  message = input(" ")
  ints = predict_class(message)
  res = get_response(ints, intents)
  print(res)

here are the errors which occurred after training the model, 

TypeError :

<ipython-input-25-b79961d9419f> in <module>()
 42   message = input(" ")
 43   ints = predict_class(message)

---> 44 res = get_response(ints, intents) 45 print(res)

 <ipython-input-25-b79961d9419f> in get_response(intents_list, intents_record)
 28 
 29 def get_response(intents_list, intents_r

ecord): ---> 30 tag = intents_list[0]['intent'] 31 list_of_intents =intents_record['intents'] 32 for i in list_of_intents:

 TypeError: 'NoneType' object is not subscriptable

 Any Help or advice Highly Appreciated
 Note : Intents they are messages which contains tag, pattern,  response in dictionary 
 and this where it shows type error in intents bit confused.
