Telegram Bot - Message Error

Hello, I am developing a Telegram bot, but I cannot import the message library. I am using Visual Studio and PyCharm, but at the beginning of the program, the line 'from telegram.ext import Updater, CommandHandler, ConversationHandler, MessageHandler, Filters' is shown as an error. The explanation says: 'cannot import name 'Chat' from 'telegram' (C:\Users\k\anaconda3\lib\site-packages\telegram\__init__.py)'. I have tried everything, but I couldn’t solve it. Can anyone help? Thanks!
