This is the code which I am trying to execute :
from future import absolute_import from future import division from future import print_function from future import unicode_literals
import logging import rasa_core from rasa_core.agent import Agent from rasa_core.policies.keras_policy import KerasPolicy from rasa_core.policies.memoization import MemoizationPolicy from rasa_core.interpreter import RasaNLUInterpreter from rasa_core.utils import EndpointConfig from rasa_core.run import serve_application from rasa_core import config
logger = logging.getLogger(name)
def train_dialogue(domain_file = ‘weather_domain.yml’, model_path = ‘./models/dialogue’, training_data_file = ‘./data/stories.md’):
agent = Agent(domain_file, policies = [MemoizationPolicy(), KerasPolicy(max_history=3, epochs=200, batch_size=50)])
data = agent.load_data(training_data_file)
agent.train(data)
agent.persist(model_path)
return agent
def run_weather_bot(serve_forever=True): interpreter = RasaNLUInterpreter(’./models/nlu/default/weathernlu’) action_endpoint = EndpointConfig(url=“http://localhost:5055/webhook”) agent = Agent.load(’./models/dialouge’, interpreter=interpreter, action_endpoint=action_endpoint) rasa_core.run.serve_application(agent ,channel=‘cmdline’)
return agent
if name == ‘main’: train_dialogue() run_weather_bot()
But it gives this error. Please help me with this error.
