Hi @addelll, I based on the stack trace I can't pinpoint the exact cause of your failed Heroku deployment. What parameters are you passing to the ChatBot class in your code?

[a-elhaddad]

the simple example didn't work with flask in heroku , i tested the example https://github.com/chamkank/flask-chatterbot

from chatterbot import ChatBot from chatterbot.trainers import ChatterBotCorpusTrainer from langdetect import detect_langs from time import sleep import json from chatterbot.conversation.session import ConversationSessionManager import uuid

chatbot = ChatBot("Adddell", silence_performance_warning=False)

chatbot.set_trainer(ChatterBotCorpusTrainer) chatbot.train("chatterbot.corpus.french") chatbot.train( "chatterbot.corpus.french.greetings", "chatterbot.corpus.french.trivia", )

[gunthercox]

Are you able to run @chamkank's flask app example locally without error?

[a-elhaddad]

yes it's working localy

[a-elhaddad]

hi just tell me best config (python version and requirements) that should i use to test it in server

[gunthercox]

Python 3.5 is the recommended version of Python for ChatterBot. ChatterBot's requirements are listed with the version ranges specified in this file: https://github.com/gunthercox/ChatterBot/blob/master/requirements.txt

[chamkank]

If it still doesn't work after that, I recommend using PythonAnywhere instead of Heroku. It worked without a hitch in the past, when I hosted the live demo.

[rajasimon]

You should add these to your nltk.txt so heroku will download these when build.

wordnet
stopwords
punkt
vader_lexicon

[vkosuri]

A example project here https://github.com/vkosuri/chatterbot-live-example

[gunthercox]

@vkosuri Does your example still work? It looks like the heroku site may be broken.

[vkosuri]

No it is working https://chatterbot-live-example.herokuapp.com/

[rajasimon]

@vkosuri I doubt that. Can you try with fresh installation. I too ran into the same problem when I deploy in the first time.
