Running bot on command line

I am trying to run the bot on command line. However, I m not sure what is the correct script for this.

loop = asyncio.get_event_loop()
logger = logging.getLogger(__name__)
async def parse(serve_forever=True):
    interpreter = RasaNLUInterpreter('./model_save/test3/nlu')
    action_endpoint = EndpointConfig(url = "http://localhost:5055/webhook")
    #action_endpoint = read_config_file('endpoints.yml')
    #action_endpoint = AvailableEndpoints.read_endpoints('endpoints.yml')
    agent = Agent.load("model_save/test3", interpreter=interpreter,action_endpoint=action_endpoint)

    return agent

if __name__== "__main__":

getting this error by running the script

RuntimeError: Cannot run the event loop while another loop is running
