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.
