body: <p>When I run the code below the following error message is displayed: <code>'TeleBot' object has no attribute 'message_handler'</code>.</p>
  <pre><code>import telebot
  from telebot import types
  keyboard1 = telebot.types.ReplyKeyboardMarkup()
  keyboard1.row('Ok', 'Bye')
  
  bot = telebot.TeleBot('API')

  def start_message(message):
      bot.send_message(message.chat.id, 'Hi what do you want /start', reply_markup=keyboard1)
      
  @bot.message_handler(content_types=['text'])
  def send_text(message):
      if message.text.lower() =='Hello':
          bot.send_message(message.chat.id, message.text.upper() )
      elif message.text.lower() =='Bye':
          bot.send_message(message.chat.id,'see you soom' )

      print(message)
  
  bot.polling(none_stop=True)

  <p>So what is wrong? I have installed pip and others. I wrote it on python IDLE. I wanted to make a telegram bot which gives stickers.</p>
