I'm trying to use the library Chatterbot, but I got this error RuntimeError: implement_array_function method already has a docstring I don't understand! Can you help me?

from chatterbot import ChatBot
from chatterbot.trainers import ListTrainer

# Create a new chat bot named Charlie
chatbot = ChatBot('Charlie')

trainer = ListTrainer(chatbot)

trainer.train([
    "Hi, can I help you?",
    "Sure, I'd like to book a flight to Iceland.",
    "Your flight has been booked."
])

# Get a response to the input text 'I would like to book a flight.'
response = chatbot.get_response('I would like to book a flight.')

print(response)

  • I have a comparable problem but with totally different libraries, using blender and self-implemented chatbot-functions. I start suspecting this must be somehow related to doubled imports... – CLpragmatics Oct 25 '19 at 12:09
  • I experienced the same type error, solved by reinstalling venv. – ZDL-so Sep 16 '20 at 12:51

See numpy issue.

Try downgrading numpy to version 1.15.4.

You may get another error like typing-extensions module not found.

Simply pip install the missing module.
