AttributeError: module 'google.cloud.dialogflow' has no attribute 'types'

I am building a telegram-bot and using Dialogflow in it, I am getting the following error :

}, 'update_id': 624230278}' caused error 'module 'google.cloud.dialogflow' has no 
attribute 'types''

It appears there is some issue with the Dialogflow attribute "types", but I don't know what I am doing wrong.

Here is the code where I am using it:

import os
os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "client.json"

from google.cloud import dialogflow
dialogflow_session_client = dialogflow.SessionsClient()
PROJECT_ID = "get-informed-ufnl"

from gnewsclient import gnewsclient

client = gnewsclient.NewsClient()


def detect_intent_from_text(text, session_id, language_code='en'):
    session = dialogflow_session_client.session_path(PROJECT_ID, session_id)
    text_input = dialogflow.types.TextInput(text=text, language_code=language_code)
    query_input = dialogflow.types.QueryInput(text=text_input)
    response = dialogflow_session_client.detect_intent(session=session, query_input=query_input)
    return response.query_result



def get_reply(query, chat_id):
    response = detect_intent_from_text(query, chat_id)

    if response.intent.display_name == 'get_news':
        return "get_news", dict(response.parameters)
    else:
        return "small_talk", response.fulfillment_text


def fetch_news(parameters):
    client.language = parameters.get('language')
    client.location = parameters.get('geo-country')
    client.topic = parameters.get('topic')

    return client.get_news()[:5]


topics_keyboard = [
    ['Top Stories', 'World', 'Nation'],
    ['Business', 'Technology', 'Entertainment'],
    ['Sports', 'Science', 'Health']
]

I figured it out, the problem lies in the import statement. The correct module name should be:

import google.cloud.dialogflow_v2 as dialogflow
